[CentOS] Network Servers window kills all Nautilus windows in CentOS 5.1?

[MHR]

In the process of doing something else, I happened to open the Network
Servers window from the Places applet menu.  When I did, it killed all my
Nautilus windows on all my workspaces.  (I had to experiment a little to
prove this, but it did happen.)

Is there an explanation for this and what?

Thanks.

That's a good one.

You can take it further (if you have more than one site/port to
connect to) - install a proxy on the remote machine (e.g. "squid" or
maybe apache's mod_proxy) and forward a tunnel to it as you describe
then setup localhost:8080 as your proxy (firefox extensions can allow
you to use this proxy only for certain sites).

[CentOS] 5.0--> 5.1 lm_sensors "General Parse Error"

[John Thomas]

Problem and solution, not sure if correct

After upgrading to 5.1 and restarting, lm_sensors complained "General 
Parse Error."  Google pointed here:

http://www.lm-sensors.org/wiki/Devices
Where I found this under "SENSOR CHIP DRIVERS - STATUS" AMD --> "Since 
Kernel 2.6.19"


Latest AMD K8 processors have integrated sensors which can be read 
directly without any additional monitoring chip. Driver contributed by 
Rudolf Marek. Userspace support available in lm_sensors 2.10.1. Upgrade 
to lm_sensors 2.10.1 is mandatory, earlier versions of libsensors will 
fail with a "General parse error" message.


My kernel is "2.6.18-53.el5.centos.plus-i686", but I figured I must of 
gotten me some backported stuff in there (i.e. I'm in over my head).


I upgraded to the lm_sensors in ATRPMS testing repo, and the problem 
went away. (lm_sensors-2.10.5-52.el5)

Both boxes are running centos 5.


don't startx on the REMOTE machine, have it running on the LOCAL machine.

local$ ssh -X remote

remote$ firefox &

and firefox should open on the local...

or you can do a port forward if you wanted to just use your local browser.

ssh -L :localhost: @

eg. ssh -L 8080:localhost:80 [EMAIL PROTECTED]

then, in your local browser, simply type localhost:8080 as the url to 
display port 80 from the remote server.

Then consider:

1. turning on maximum compression ("-C" switch to ssh).
2. If you can switch to VNC or NX then do it, apparently it works
better than X11 over long distances (and from the docs I understand
it's possible to have VNC/NX for one window, no need to setup an
entire desktop for that).

Why? It's less secure and -X is good enough 99% of the time (I always use -X).

First - make sure you have "xauth" installed on the remote machine.
With CenttOS 5 it comes in xorg-x11-xauth. Ssh needs it to pass over
the x11 authentication cookies (e.g. I don't install X environment on
my servers so I have to remember to install this package separately).

Secondly - when you login through SSH, type "echo $DISPLAY" and see if
you get anything - if not then X11 isn't being forwarded yet.

Also I hope you start ssh after having X11 environment started on your
local machine and from a shell which has $DISPLAY set correctly
*locally*.

When all these tests are passed I usually try to run a basic X11
program like "xlogo" but you might not have it so just try to run
firefox again and see what happens.

VNC does not have any encryption built in so remember, if you are using
over any network, your login/passwords/traffic are not encrypted.
  
'They' tell you to run vnc at localhost, and ssh tunnel for the 
security.  But one senario of use has the server connected to the client 
via a crossover cable, so I am not concerned about packet sniffing!

FreeNX handles all that for you PLUS it gives you really nice data

No need to start X on the remote machine.  You need to do "ssh -X  
" so that X is forwarded (back to the machine that you  
ssh'ed from).  Make sure that "X11Forwarding yes" is set in the /etc/ 
ssh/sshd_config file (restart the sshd if it was not).  Then you can  
simply type "firefox &" and it will appear on the machine you started  
the ssh from (assuming of course that a X server is running  
locally).  This of course works for any X11 application, not just  
Firefox.

First, man ssh, so you can read the ssh manual. Second, make sure on the
remote host that this line is in /etc/ssh/sshd_config.

X11Forwarding yes

Then run ssh while forwarding X

[CentOS] Kickstart + CentOS 5 = doesn't prompt for network information?

[Ray Van Dolson]

This may be more appropriate for an upstream list.  That said...

I'm doing kickstart setups of CentOS 5.  My kickstart config includes a
network configuration item.  Depending on options passed at boot-time,
the network config item may or may not include a --hostname option, but
always specifies eth0.

When I do a kickstart install, I notice that even though I am using
'interactive' (basically so the user can override any of the kickstart
settings should they need to), the networking screen never pops up and
the values from my network get used.  If the usr didn't provide a
hostname entry on bootup, then localhost.localdomain gets used as the
system hostname.

I'd like for the user to be able to select the hostname via the
installation wizard as they would normally in a non-kickstart install.

Perhaps for CentOS 5 kickstarts I should just not include the network
option at all in order to make the network configuration screen
accessible inside the installer?

[CentOS] re-installing a package without removing it?

[Amos Shapira]

Hello,

I've just noticed that the file /etc/ha.d/resource.d/drbddisk, which
belongs to package drbd-8.0.6-1.el5.centos, is missing from one of my
test machines:

# rpm --verify drbd
S.5T c /etc/drbd.conf
missing /etc/ha.d/resource.d/drbddisk

I'm looking at this as an opporunity to learn something about RPM
which bugged me for a while - in Debian, aptitude and apt-get provide
options to re-install existing package without removing it.

If I understand this correctly, then "rpm -i --force
drbd-8.0.6-1.el5.centos.rpm" would re-install the package. Is this
correct?

The rpm solution would require me to find and manually download the
rpm file. Is there a way to do this through yum?

Thanks,

Hello,

I'm new to the linux world (long time FreeBSD user), and I'm wondering 
if there's an easy way to install CentOS 5 without the GUI and

didnt see anything like that for CentOS 5.  Am I looking in the wrong 
places, or is it just necessary to manually select the minimal set of 
packages?


Firstly, I want to clear up this misconception that people have that the 
ServerCD is a minimal install. Well, its not. Its a typical Server install, 
which is - trust me - very far from being a minimal install.


Secondly, the best way to do a minimal install is to just get the netinstall iso 
from the 5.1/isos/ directory, run a normal graphical install, and deselect all 
options from the 'Tasks to install' screen, select customise now option, then 
deselect everything from the next screen as well. It should give you a minimal 
install, with just enough packages to have a booting system, network and a 
functional sshd server. Once installed, you can then carry on adding packages 
with yum.


Finally, I believe this is FAQ number 1, check wiki.centos.org's FAQ section for 
CentOS-5

I know the topic of a server cd has been bought up a few times and I think
one was "unofficially" made for 5.0 from a group in South Korea(I may be
wrong) but there is also a wealth of info in the server sub-forum of the
Centos.org website in regards to server setups it may help a bit:

Re: [CentOS] Re: Please help me rate vnc, rdesktop, and freenx

[Dan]

Mainly it will all depend on "your" server specifications and network
setup.  We use VNC to remotely control the Windows boxes on the network and
it does an ok job, but even T1 to T1 we have a bit of lag.
We also use FreeNX for remote desktop features and it is quite fast from
home to office, it does have its quirks though.
So in all try them out in a lab and see which one is the best fit for you.
I have to agree though that for "everyday" use ssh is just fine.

[CentOS] Yum FTP concurrency

[Tom Lanyon]

Greetings,

My chosen CentOS mirror has a limit of 5 max FTP connections per IP. A  
simple 'yum update' is hitting this limit and causing the whole update  
procedure to fail.


Are there any settings to limit yum's FTP concurrency?

The problem probably has something to do with anaconda shifting into  
graphics mode when anaconda starts but the mode isn't compatible  
with the laptop's LCD display.  Using nofb tells the kernel not to  
use frame buffers which keeps the install in a standard (e.g., VGA)  
mode or the external monitor works with the display mode.

Dave,

Thanks - can't believe I didn't think of the framebuffer earlier.

Using nofb does indeed allow me to progress with the installation.

I do that now with the ATRPms repo. It can conflict with rpmforge a lot, but 
the two were not meant to be used together. One works for more backward 
compatibility, while the other works for addons that might change the function 
of the system. CentOS's own "plus" repo does the same. It isn't good or bad in 
itself, you just need to make choices on what you want to accomplish.

[CentOS] Re: RHEL 5 vs. CentOS 5

[Scott Silva]

on 12/6/2007 3:25 PM Lopez, Denise spake the following:

Hi all,

 

I would like to first preface this e-mail by saying if this topic has 
been covered already, could someone point me to the month of the 
discussion and I will gladly read it.


 

We have been using RHEL 3 / 4 in our environment and I am very happy and 
satisfied with the stability of the OS.  Now with the new technologies 
incorporated into RHEL5, specifically Virtualization, Clustering, and 
Storage, and the costs associated with them, I was wondering how similar 
CentOS and RHEL 5 were.


 

It is my understanding that CentOS is RHEL 5 with the RedHat icons 
removed but the functionality of the packages is the same.  In addition, 
updates may come a day or two later than RHEL 5. 

 

My boss is a little concerned about the differences since we host 
production servers that require minimal downtime.


 


Any thoughts and opinions are very welcome.


The choice comes down to this;
If you require to have a support contract, and a live person on the other end 
of the telephone when you have problems -- Use RedHat's offering and pay the 
support.


If you are willing to test things on non-production servers, and use public 
resources to work through problems -- Use CentOS. The money you save on 
support costs will more than offset the cost of a few test systems to run 
updates through.


CentOS uses the same system and source files that RHEL uses, and it is 
probably the distribution that is closest to the RHEL offering -- sometimes 
too close, because if it is broken on RedHat, it will probably be broken on 
CentOS also. The CentOS maintainers also have had success finding bugs and 
proposing fixes to the RHEL bug system, which benefits all.


There are many commercial ventures running on CentOS and other similar works.

We use centos for "all" servers which do not "require" a support plan from
Red Hat. I wonder what would happen if we purchased a support license for a
centos box after the fact?

Correct.  In addition, I think the CentOS kernels are basically the
"AS" kernels, and obviously there is no activation key, nor will you be
able to use RHN for errata notification, etc.

you issue 'service vncserver restart' command from any command line
(i.e. ssh)

VNC does not have any encryption built in so remember, if you are using
over any network, your login/passwords/traffic are not encrypted.

FreeNX handles all that for you PLUS it gives you really nice data
compression (better performance over limited bandwidth).

Darn straight. And using ssh-agent (or Pageant with PuTTY on Windows) in
conjunction with key forwarding, you can make it easy to script stuff that
runs across multiple machines, thereby automating an entire server farm, if
you want to. Unix admin maxim: if you have to do something more than once,
write a script for it. See
http://www.lesbell.com.au/Home.nsf/web/SSH+for+Server+Administration?OpenDocument

We certainly don't want to revert to the "point-and-grunt" method of doing
things found in the Windows world. I thought we'd put that behind us when
we stopped living in the trees.

It's OK to just update the kernel, however, why not update everything?
 There's really no good reason not to do a 'yum update'

Yum has the 'installonlyn' plugin, which will remove old kernels for
you.  By default, it is configured to keep 2 copies.

To upgrade the kernel to CentOS 5.1 (to take advantage of support for
Dell wireless card bcm43xx), should I update everything or just type
'yum update kernel', or what? Also, is it OK to remove 'old' kernels
(which appear in the boot list) when they are no longer required?

There are numerous ways to remotely access a Linux machine, and
honestly the "remote desktop" style that Windows uses is the worst of
them.  VNC, rdesktop, and freenx all replicate that method of access,
where you basically get a picture of what would be on the monitor if
you were sitting at it.

As was already mentioned, ssh is really the main way for remote
access, but for people not familiar with Linux, there's no GUI and no
mouse beyond copy/paste, so you may look for another solution.

The real *NIX way of accessing a graphical application remotely is by
using a remote X desktop.  It sounds strange if you're not familiar
with it, but basically you run the 1 application on the remote server,
and the application window (and only the application window), shows up
on your local workstation.  SSH provides a way to do this securely.
The drawback is you will need an X server running on your local
computer, but that can be had for free in Windows from cygwin.

Having stepped your foot in all of that now, the simplest GUI to get
working is the vnc/freenx style of remote access.  I have only used
VNC, and it works well enough, but I hear good things about freenx.
If you go the VNC route, make sure to set up a firewall to block
direct access to the vnc port, and only access it through ssh
forwarding, as vnc is not secure by itself.

Ok the problem field is that you have N different repositories, using
M different guidelines, using O different compile flags, and P
different filesystem layouts.

The constraint is simply that you do not replace any file/library with
one that is incompatible.


And how do you know it isnt compatible? Keeping ABI's the same is
extremely hard work and basically would mean that a repository rarely
puts up new stuff but only backports items from upstream. Thats a lot
of work for something they don't get paid for. And even if the ABI is
the same, it doesnt mean that you have different actions occur because
one had a compiler with XYZ flag in it and the other had XZY.


The Sun people like to claim that you can run
anything that ever ran on Solaris on subsequent versions so the problem
space isn't as impossible as you make it seem - it is more a matter of
respecting interfaces and backwards compatibility.


And that was a load of bull from Solaris. You could run most Sun
things from Solaris 2.x to 2.x1 but the list of things that didn't run
as expected was always pretty long. And to do that they had to
basically strip down the OS to extremely limited functionality. That
was why it was such a 'radical' change when they started shipping GNU
tools in the OS because it had been requested for years but the amount
of churn was too high for them to want to deal with.


But my point is that
I don't want to be forced to use a repository that always follows this
constraint.  Sometimes compatibility is what you want, sometimes you
want something different, and you need to be able to manage both.



But are you willing to pay for that? Because its not an easy problem
to solve that people can throw more computers at and get it working.
It usually requires a lot of meat-ware time with people working out
meat-ware politics and issues.


The best you could possibly do is not
have packages at all but keep each package in a dmg file and let the
ld fight it out over who gets executed today... but that would seem to
be a different OS.

Yes, that would make Linux as difficult to maintain as a Mac.



Maintainability is usually on the opposite side of choices.





guys, while somewhat relevant - this list is really not the place for 
this conversation. As has happened before its going to go round in 
circles with lots of noise - but no action.

Ok, well it isn't pretty, but it's the only way to do it, I am
posting a general RPM specfile template that outlines it.

Once you have the spec file created you can do an:

# rpmbuild --target=$(uname -i),noarch 

And it should build the binary and noarch.

Here's the template:

Actually it would have been the case at some point as soon as it was
looked at that they would use Fedora packaging standards versus some
other set of standards.. The guidelines that you, DAG, etc conflict in
various places and conflicted before EPEL was a gleam in its parents
eye. It is also because you serve different audiences. I know that if
I want bleeding edge packages that will pull in all sorts of new
Perl/Pythons etc.. I have used ATrpms because you do what is needed to
get XYZ-9 working. DAG might on the other hand may decide that XYZ-9
is not going to be supported in the same way because on RHEL-3
bringing in Python-3.00beta is just too much of a headache especially
if its going to break everything else.

Mixing the two repositories in that case will cause unintended
problems.. which at that point the repotags would be helpful in saying
'well don't mix them in this case' but wont have stopped the problem
from occurring in the first place.

However at some point people quit thinking logically and instead
started just throwing virtual dung at each other like we hadn't
evolved much in the last million years. And after that everyone spent
time trying to point out that the other side started throwing the dung
first and if you didn't agree with that you had to be on the other
side and oh here is some dung. Of course saying 'well let bygones be
bygones' isn't going to happen until the other side publicly castrates
itself as a sign of good faith.

I would say that the only thing that needs to top this off is some
rumours that the other side is going to use bitkeeper for its source
control, or ESR saying they thought that ZYZ was now his preferred
repo and RMS saying that the other was the only true repository.

I don't recall there being an issue vs runlevel 3 or 5

First off, nx is a much better way to go

Anyway...what's contents of /etc/sysconfig/vncserver ? Is it configured?

I remember that this was either impossible or really hard to do long

out into 2 different source rpms than trying to get RPM to do it.

As mentioned before, IO could give such strange results. I suggest

Thanks, much appreciated!

This has yielded some interesting data, which I'll attempt to include  
a few seconds before and after one of these events occurred.

Everything else looks sane -- there's enough ram, nothing's being

balancer in front of it, so if it's network related, it wouldn't be  
misdirected random bits.


Has anyone seen this sort of behavior before? What was the cause? What  
should I do to figure out how to keep the load averages from flipping  
out of control?


(This isn't something as lame as a counter rolling over somewhere

Running 2.6.18-8.1.8.el5. We could reboot to run 2.6.18-8.1.15 if  
that'd be a potential fix.)


Thanks for any insight!

Oh, no, don't put the blame on ATrpms ;)

The repotag issue was just a frontend where the non-cooperation of
EPEL with the rest of the world was demonstrated to beyond anyone's
imagination. Only after several people that EPEL was trying to attract
turned their backs and upon that some RH officials raised their heads
to the EPEL "chairmen" where there some reevaluation about repotags.

So repotags was a small issue which failed on EPEL's
non-cooperation. I don't see why more important issues would ever have
a better faith, and I lost a lot of momentum in this fake
discussion. The bottom point is that EPEL just wanted to enter the
repo world of RHEL/CentOS and friends w/o caring about what existed
there, and placing any compatibilty burden on others' shoulders.

No *technical* solution will ever solve this. Even the best package
manager in the world cooking coffee in its idle time will not solve
packagers not talking to each other and creating conflicting and
incompatible packages. And we've tried talking and coordinating, it's
the EPEL side of the world that decides to play the Highlander theme
again ("there can only be one").

So to answer the subject: No, EPEL is incompatible to every other repo
that existed before EPEL came up. That was not the original promise of
EPEL (I know as I was a steering member before I gave up on this
insanity course), but it developed that way.

And how do you know it isnt compatible? Keeping ABI's the same is
extremely hard work and basically would mean that a repository rarely
puts up new stuff but only backports items from upstream. Thats a lot
of work for something they don't get paid for. And even if the ABI is
the same, it doesnt mean that you have different actions occur because
one had a compiler with XYZ flag in it and the other had XZY.

And that was a load of bull from Solaris. You could run most Sun
things from Solaris 2.x to 2.x1 but the list of things that didn't run
as expected was always pretty long. And to do that they had to
basically strip down the OS to extremely limited functionality. That
was why it was such a 'radical' change when they started shipping GNU
tools in the OS because it had been requested for years but the amount
of churn was too high for them to want to deal with.

But are you willing to pay for that? Because its not an easy problem
to solve that people can throw more computers at and get it working.
It usually requires a lot of meat-ware time with people working out
meat-ware politics and issues.

[CentOS] RPM Spec and subpackage architecture

[Ross S. W. Walker]

Are there any RPM wizards out there that know how to specify a
different architecture for a subpackage in a spec file?
 
I have a package that has a binary component and a non-binary
component that I would like split into 2 packages one, the
binary which is architecture dependant and the other 'noarch'.
 
I haven't found a spec file that does this yet :-(

[CentOS] Re: A few questions about remastering

Hi,


If you absolutely insist on rebuilding .. you can't call your product
CentOS or use our logos.  You can say that the product is based on CentOS.

I don't see why one would do this though, as CentOS can support millions
of users right now and is totally free to distribute in an unmodified
form.  And it is MUCH easier to only distribute several updated packages
than all those plus all ours.

Now that Prof. Dan Bernstein has put his software in public domain, I'd
like to create a distro based on CentOS that installs a complete email
server.

That's why I want to rebuild.

I believe that SMEServer is based on CentOS and already smears itself full of 
qmail. And it has nice web-based configuration pages, too!


Maybe fork from there, and use a kickstart to prune or add things you want.

While this isn't available on Linux it proves that there is market

Yea, I originally got the idea from the NetApp marketing materials.

But the netapp appliance has a processor that is only doing so much. It isn't

I sorry was not very clear. I do know the SCSI drives have their own
bad block table but it appears from the description of the SCO OSR5
badtrk utility that OSR5 may also maintain an OS level bad block
mapping capability as well. I still would like to see the SCSI bad
block table but I cannot expect Linux to support what might be an
SCO OSR5 specific feature.

Ahhh IRIX, I remember it well but it has been many years since I worked

making a come-back. That will be interesting to see.

I never had the opportunity to work at that level. That was handled
mostly by the SGI techs. This does bode well that I may be able to
get at this data in Linux if I can just find the right utility.

Ok the problem field is that you have N different repositories, using
M different guidelines, using O different compile flags, and P
different filesystem layouts.


The constraint is simply that you do not replace any file/library with 
one that is incompatible.  The Sun people like to claim that you can run 
anything that ever ran on Solaris on subsequent versions so the problem 
space isn't as impossible as you make it seem - it is more a matter of

The best you could possibly do is not

Ok the problem field is that you have N different repositories, using
M different guidelines, using O different compile flags, and P
different filesystem layouts. The best you could possibly do is not
have packages at all but keep each package in a dmg file and let the
ld fight it out over who gets executed today... but that would seem to
be a different OS.

[CentOS] Re: Load Balancing

[Rajagopal Swaminathan]

Greetings,

First let me thank the gentleman who allayed my fears about CentOS 5.1's
"yum update" download size. but all the same it turned out to be in
megabytes. not to mention the k3b *roasted* couple of DVD's to uselessness
and I am still giving explanations to the stupid ancient,retired, former
stupid cretin bean counters masquerading as "managers" and "management
Accountants" on. a piddly amount wasted.

I found this thread in the GMANE list as I subscribed to this list rather
late.

Let me propose a solution:

Let two nodes run the greatest ever CentOS 5.0 on two nodes.

Let two nodes of the cluster run DRBD 0.8 and export block devices in
Primary/Primary mode and the GFS be mounted on them.

Let the NFS export be a managed service of the Cluster infrastructure from
these nodes exporting the NFS on a cluster managed virtual IP as rw.

let n (as permitted by the infrastructure) nodes import NFS as client on
their nodes. and do the job

I am seeing a 3-node cluster exactly that far past fes days and naturally,
given the maturity of CentOS 5, do that for, hopefully, ever.


In the ,eantime of the replies hopefully the readers will enjoy the
solutions proposed by me

regards,

Yes : when you have production machine using such modules (sitting in
the extras repository, or third-party), i advice you to exclude the
kernel (exclude=) in your yum config ... i *always* update manually such
things, especially when dealing with sensitive data that needs to be
replicated through DRBD ...

My two cents ..

[CentOS] Prevent kernel upgrade unless given dependencies satisfied

[Ross S. W. Walker]

Dear List Members,
 
Is there a way to prevent a kernel from being upgraded unless
a list of given dependencies are satisfied?
 
What I am getting at is sometimes updated kernels are available
before the upgraded versions of the kernel modules in 'extras'
are (ie drbd).
 
If there were a way to list these modules as dependencies that
must be satisfied before a kernel upgrade can be performed it
would prevent a lot of pain around upgrade management.

Yes, but it really needs to be tracked at the installed file level so 
that rpm and yum could refuse by default to overwrite any existing 
filename with a version from a different source unless it explicitly 
obsoletes the one to be replaced.  That way the conflicts couldn't be 
accidental and if you want to replace someone else's file you'd have to 
say so.

Speaking from a technical standpoint, the biggest issue with mixing
any different repos is that they use different packaging guidelines.
The hyperbole case:  package repo A uses  SuSE standards, repo B were
to use Fedora 1.x standards, repo C were to use current Fedora
standards, and repo D were to use Mandrake standards.. you would end
up with either file conflicts or worse yet lack of conflicts but
hidden requirements (script from A expects files to be in
/opt/blah/bin for some reason but you got that package from E because
it was newer and it places things in /srv/snozzberry/bin instead.

The more common case I have found has been odd dependency chains from
one side or another because of unclear guidelines. In most production
environments, I tend to choose one repository and then work with that
one only to get the job done. For some things it was ATrpms, others
DAG, and other EPEL. If the item I needed was in one but not the
other.. getting it into the one repository I was working with was
easier than trying to figure out how to find any unknown unknowns in
hidden conflicts.

As DAG has said several times in mailling lists.. the proper thing to
do is not use a repository directly anyway. You should have an
internal mirror of the main repo, and then several sub-repo's of just
the packages you want your systems to have. You should have a testing
routine where you take new packages test that they work with your
environment and then push them out from the sub-repos. He has written
several tools to make this possible..

No.  What exactly are you getting at? :)

Seems like this issue is kinda moot at this point... and honestly,
although maybe it would have been _nice_ for EPEL to use repotags, I
think their thinking is that Fedora and Fedora Extras in the past
doesn't use them; they consider themselves "upstream" in a way and are
sticking to that same behavior.  They also didn't feel that repotags
were really a good solution to the problem.

Many discussions and arguments occurred, but in the end this is how it
worked out.  And if I recall, EPEL did finally agree to use repotags,
but ATrpms had already removed all repotags from their packages so the
driving reason to do it was at that point gone.

It's unfortunate, but doesn't seem like it's going to change.  I guess
that doesn't mean we need to stop talking about it, but maybe instead
of hollering about the need for repotags it's time to collaborate in
the other direction -- building a better way to track reopsitories into
the RPM database itself.

I would disagree. The gauntlet was laid down with the Bible quote which is:

 14What good is it, my brothers, if a man claims to have faith but has
no deeds? Can such faith save him? 15Suppose a brother or sister is
without clothes and daily food. 16If one of you says to him, "Go, I
wish you well; keep warm and well fed," but does nothing about his
physical needs, what good is it? 17In the same way, faith by itself,
if it is not accompanied by action, is dead.

 18But someone will say, "You have faith; I have deeds."
  Show me your faith without deeds, and I will show you my faith
by what I do.

 19You believe that there is one God. Good! Even the demons believe
that—and shudder.

 20You foolish man, do you want evidence that faith without deeds is
useless[a]? 21Was not our ancestor Abraham considered righteous for
what he did when he offered his son Isaac on the altar? 22You see that
his faith and his actions were working together, and his faith was
made complete by what he did. 23And the scripture was fulfilled that
says, "Abraham believed God, and it was credited to him as
righteousness,"[b] and he was called God's friend. 24You see that a
person is justified by what he does and not by faith alone.

 25In the same way, was not even Rahab the prostitute considered
righteous for what she did when she gave lodging to the spies and sent
them off in a different direction? 26As the body without the spirit is
dead, so faith without deeds is dead.

He was just quoting back what you had said.. in a different format.

For the most part, yes, I'd argue the vendor/packager combo should come

In a system that might want to call itself a community, I don't see why 
a particular package couldn't be served from more than one repository. 
Is there some rule about that?

This is a problem space that sure could use some love and attention, with

There are lots of things that RPM packaging doesn't handle very well and 
won't for the foreseeable future.  Meanwhile we need to do things with 
conventions and workarounds since that's all we have.  And there's 
nothing wrong with making things visible with filename conventions.

This is a bit different then what I was proposing.  I know that backupPC

It also collapses multiple runs of the same machine so you can keep a

Block level would help 
a lot more I think.  You'd be able to do a full backup every night and 
have it only take up around the same space as a differential backup.  


Agreed, but the main difference would be in big files that change 
slightly, like growing log files, or mailboxes in unix format.  These 
are often compressible, so there is some tradeoff, and you can make 
things more backup-friendly by switching to a one-file-per-message mail 
format like maildir and rotating log files often.


Things like virtual machine disk images which a lot of times are clones 
of each other, could take up only a small additinal amount of space for 
each clone, proportional to the changes that are made to that disk image.


Some virtual machine managers (e.g. vmware workstation) already provide 
this facility - and you might be able to get it with one of the existing 
overlay filesystems if you are willing to start with an immutable base. 
However, I agree that it would be really nice to have a filesystem that 
overlaid blocks of identical content with full copy-on-write semantics 
to permit any instance to be modified transparently.  If it had some 
concept of large/small block sizes and had a good hit ratio on the large 
blocks it might not add that much overhead.
