[gentoo-user] net-misc/wget-1.13.3-r2: unexpected behaviour with some options

[Casper Ti. Vector]

With net-misc/wget-1.13.3-r2, when executing `wget --version', I get
"GNU Wget 1.13.3 built on linux-gnu.\n\n+digest "
(intepret as C string, you migh need to note that there is no newline in
the end of the output); when executing `wget --help', I get
"GNU Wget 1.13.3, a non-interactive network retriever.\n"
(also intepret as C string).

This seems to be a bug since with `--help', wget should print its
options; and with `--version', wget should print its compile-time
configurations, which should be more than 20 lines.

My Gentoo system is updated daily with global ~amd64 keyword in use.
USE flags of net-misc/wget-1.13.3-r2:
ipv6 nls ssl -debug -idn -ntlm -static

[gentoo-user] dev-lang/R: lots of "Error in strsplit" in using

[Casper Ti. Vector]

When using R on my Gentoo machine, whether in interactive or in batch
mode, calling `help()' causes the following error:
Error in strsplit(txt, "\n", fixed = TRUE) : 
  'split' string 1 is invalid UTF-8
When in interactive mode, typing any function with an opening bracket
(eg. `help(') and then pressing tab (intending to get a command
completion) causes the same error.

Above is the situation in the default locale on my machine,
`en_GB.UTF-8'; and with LANG=C, this does not happen.

My Gentoo system is updated daily with global ~amd64 keyword in use.
Available locales as following:
C, en_GB.UTF-8, POSIX
USE flags of dev-lang/R (version: 2.13.1) as following:

I don't see any problem with an initramfs larger than the kernel. It
will handle a lot of stuff. But if you don't want to change your /boot
partition, then don't upgrade to new kernels.

Change happens.

So, you guys want a separated /usr, but don't want a separate /boot. Awesome.

I didn't say they were invalid, I say that *I* don't see the reason to
separate /usr. The arguments exposed just don't convice me. But
anyway, you will be able to do it with an initramfs.

Yeah, first time I installed Linux, it required 512 Mb (if I installed
X), and 16 Mb of memmory. Change happens. I welcome it happily,
because that's how we progress and get even better stuff.

If you don't like the idea, better hope over to -dev and help come up

More than this, one can put /usr on a stripe set so that /usr/bin
and /usr/lib, two of the directories with the highest I/O traffic, can
be made more performant.  But this requires LVM, RAID or some blend of
both.  This, in turn, precludes that it be merged with /, unless the
initramfs grows even more to handle those extra DASD management
facilities.

The more I think about this merge of / and /usr, the dumber I think the
idea is.  As I wrote in an earlier message on this list, the initramfs
will be many times larger than the kernel itself.  Indeed, my /boot
partition is only 32 MiB, and that will be too small to contain all the
extra libraries and programs to run the initramfs script.

Because you can't boot from an LV, so you'd than need a separate /boot
and an initramfs. Without LVM, you are unlikely to be able to resize /
or /usr as it is not usually the last partition on the drive.

This is longer than the init script needed in an initramfs. I wonder what
problems you'd have when booting as the kernel tries to update the likes
of /etc/mtab on a read-only fs.

A few months ago, I had to recover a live Debian machine which had
massive filesystem corruption in /usr; the hard drive it was on had
begun going bad, and it was taking out /usr slowly.

I wound up being able to recover by doing a full reinstall of all
packages on the live system after mounting /usr into a freshly-mkfs'd
new lvm volume. If I'd taken the system offline, it would have been
much more difficult.

(As it was, I was shocked it worked)

So, no hobbyists? Operating a 'sane' environment at home isn't how
I've taught myself Linux. In a production environment, sure; having
everything possible be read-only is nice, from a security standpoint.

Yeah, great. Used to be, I could configure needed components to be

Why not allow / to be resized entirely? You probably will take the
machine off-line anyway.

mount -o remount,rw /
emerge --sync && emerge -uDNv world
dispatch-conf
mount -o remount,ro /

Or, if you only want to modify some configuration file (which in a
sane environment doesn't happen that often):

mount -o remount,rw /
adduser fulano ...
mount -o remount,ro /

Again, I don't see the reason for a separated /usr. But *again*, if
that's what you want, you will be able to do it. You will just need an
initramfs.

Putting it on a logical volume is one advantage, allowing /usr to be
resized should the need arise.

Putting /etc on a read-only filesystem seems a really bad idea.

I think it's a useless local optimization for no real world gain
which only increases the complexity of your systems. Use the same filesystem
you use on all your other servers.



Well, for all my other servers, I standardized on ext4.

Since a vFirewall have to perform lots of packet-juggling, I'd rather
dedicate the CPU time to the kernel rather than the HD I/O.

Of course, a vFirewall needs to be updated every now and then, but
everytime an update is called for, it should not overly tax the CPU
and degrade the netfilter framework.

Rgds,


	You are making my point for me, but not realizing the end result of the 
logic. There isn't any filesystem change that is going to affect CPU 
usage by more than a few percentage points in the use case you've 
described. Rsync, portage, and gcc use a massive amount of CPU compared 
to the amount the filesystem changes will use other than brief points 
during the rsync. Additionally most benchmarks are testing filesystem 
throughput and comparing it to CPU. Because disk IO isn't under pressure 
in your scenario you're unlikely to see the pathological use of CPU that 
can highlight the differences between filesystems.

That said, you have a few reasonable choices.

1. Move to a binary distro
2. Use buildpkg on a clone of this server and only install packages on 
your Firewall.

3. NFS mount /usr/portage when you need it and dist build on another server
4. Don't upgrade
5. Get a firewall server with more CPU so that it doesn't matter
6. Script a new firewall server install every x months and swap it into 
place and drop the original server.

7. Some combination of the above.

Re: [gentoo-user] Filesystem with lowest CPU load, acceptable emerge performance, and stable?

[Jesús J . Guerrero Botella]

JFS is very soft on cpu usage, and ext4 does a very good job overall.
fsck times for ext4 makes it probably the best choice for a server,
plus it has more eyes watching over it.

In any case, I wanted to call your attention that this might not be
the best choice anyway. If you truly want portage to have the minimum
possible impact on the performance of your machine(s) you should
probably be using other machine(s) to build binary packages, then use
these package in the target system(s) (i.e. with emerge -K).

Many thanks friend.  That one bit is the key to all of it.  Just a

I'm pretty sure (but could be wrong, I haven't used genkernel in ages)
that there is a way to blacklist some modules and force others.

 It is my understanding that /usr does *not* need to be on /, only that
 if you do, you will need an initramfs. Look at
 http://article.gmane.org/gmane.linux.gentoo.devel/72275 and the thread

It's another initramfs creator. Since I use systemd and wanted to try
plymouth, I started to use it. In my case it works, and I get a really
nice splash screen at boot time.

I use the proprietary NVidia drivers, so genkernel went away very
early in my system's lifetime. I hadn't heard about dracut until

http://article.gmane.org/gmane.linux.gentoo.devel/72275 and the thread

After reading that, and other similar threads, I still don't
understand the benefits of a separated /usr. Mounting it read-only
seems the only sensible one, and then I think is better to go all the
way and mount / read-only.

But that's just me: anyway, anyone will be able to keep /usr in
another partition if so they desire it. They will only need to use an
initramfs.

[gentoo-user] altgr-intl keyboard layout

[meino . cramer]

Hi,

from here I learned the altgr-intl keyboard layout:
http://dry.sailingissues.com/us-international-keyboard-layout.html
which I will try. It seems to be a good choice for daily
programming and writing (I need german Umlauts...;)

Instead of altgr-intl: Is there a windows equivalent, for
which I can search to find a howto to establish this 
kind of keyboard-fu on my keyboard at work, where there
is no Linux reachable?

Thank you very much for any help in advance!
Best regards,

This will be a MAJOR issue if /usr needs to be on /.

I believe NetworkManager provides WPA supplicant functionlaity, so I
don't think you need wpa_supplicant if you have NetworkManager. It's
been a *long* time (about five years) since I messed with wireless
configuration daemons, though. Lots of things can change in that time,

Well, I figured this part out. Essentially, I had wpa_supplicant, and wicd 
installed.
However, what I really wanted to NetworkManager and KNetworkManager installed.
So I removed wicd, and installed NetworkManager and KNetworkManager.
I now get the interface I expected under KDE and don't need to use wpa_gui any 
more.
Still, it doesn't scan.

At least from the applications I am not getting any error messages. I'll have 
to check the logs tonight and let you know.

This morning I checked the antennae to verify they were properly connected to 
the mini-PCI card (as I had opened it up a few weeks ago to see whether it was 
mini-PCI or mini-PCIe; but I didn't remove/disconnect anything at that  time). 
Everything checked out. So it shouldn't be a hardware issue unless the card is

Are you asking how to set the page which opens the first time you launch 
Opera? With the version I have installed (11.50.1074), you have to click on 
the Opera button, just below the title bar and at the left of the first open 
tab. A menu will popup. There you'll find a 'Settings' menu and a 
'Preferences' submenu inside it. Clicking on Preferences displays a dialog 
where, in the General tab, you can choose the starting page. There you can 
also tell Opera to always load a saved session or the last used one.

Please, be aware the names of menus and dialogs I mentioned above may be 
slightly different from those: I have installed Opera in Italian, so I don't 
kown what are the English versions of the names.

I hope this helps

Hmmm... that gives me an idea...

If I have some free time, I'll experiment with doing an 'emerge -e
@world' on the various filesystems, and recording their total time
*and* CPU load.

Is the `sar` utility good enough to record CPU load?

Well, for all my other servers, I standardized on ext4.

Since a vFirewall have to perform lots of packet-juggling, I'd rather
dedicate the CPU time to the kernel rather than the HD I/O.

Of course, a vFirewall needs to be updated every now and then, but
everytime an update is called for, it should not overly tax the CPU
and degrade the netfilter framework.

Indeed. If I need more RAM, they will only sell a complete package of
vCPU+RAM+Storage, which will then be merged with my current package.

They do offer Storage-only add-on packages, though. But that's beside the point.

Pretty lame and pretty OT, but here it is:

I've installed Opera... in the last 40 min or so, I've attempted to
determine how to set a home page.  Googled etc.

Directions found on google appear NOT to apply to linux version.

Navigate to and click the preferences link at top of opera page.

NOT... there is no such link.

So, how is it done... well maybe a preferences file found in ~/.opera/

vim operaprefs.ini  ... and then insert:
Home URL=www.google.com/ig   
   (save and restart) .. once again NOT.

Even watched a video... which shows a nice person clicking on
preferences Icon... but well ... there isn't one.  Check all available
toolbars by clicking `customize' on existing top mast but not finding
a menu like that.

Is opera really so poorly designed as to make such a simple operation
so time consuming, or am I missing something really basic (as usual).

How is such a simple operation done?

Pandu is building a firewall. Putting a ton of RAM in it just for the
sake for system updates is plain overkill and -- depending on his IaaS
provider -- pretty expensive.

Already done, except I'm using X10, which means I can also control them
from my phone or the TV remote :)

I would, instead of rewiring it all, replace the switches with those remote-
control ones and simply control it from a tablet-pc :)

Thanks to both of you (Justin, Tamer).

All this doesn't answer my question, but OK, I will find my way ...

Re: [gentoo-user] Dependency Problem with Bind and Mysql

You have to resolve the build issue in the way that suits you best.
Since i'm not using the mysql integration features with bind, there's
no reason to forego threads in bind to permit support for something
i'm not using.
