You could do one install using the

yumex-dnf if you want to use yumex.)  Then either keep track of all the 
changes you make or look through the dnf log to find all the changes. 
Modify the %packages section of the auto-generated kickstart file from 
the install to match the final result you want.  Then you can use that 
to install the other computers (assuming you want the same setup on all 
of them).



It would be well worth the risk to upgrade the whole shebang, two
or three times at least, between installs. But you can't do that with live
media, which seem to be all there is on the download site.

There used to be options like fedup, or yum upgrade as opposed to
yum update. Is there a dnf equivalent? How/Where do I get it??


Yes, you can still use fedup (I do), but it is the same as "dnf 
system-upgrade".  See https://fedoraproject.org/wiki/DNF_system_upgrade 
for more details.

fedup is now the same as "dnf system-upgrade".  And there is a yumex-dnf

Guidance on resolving/reporting this is greatly appreciated.

Can you look at xfwm4-tweaks-settings -> Compositing

and see if enabling that "fixes" the issue?

Or if it's enabled, you could try disabling it. It seems like a
compositor related bug to me.


So far so good with turning this off.

While I have not tried to run vbox under fedora since for me that would

upgraded vm's running w7 to w10 successfully on both vbox 4x & 5x all 
w/o degrading windows activation and across substantially different 
hardware and even with Windows Server os's. It's a matter of keeping 
track of & managing the machine uuid which is what vbox uses to report 
hw to Windows and what Windows reads to determine whether or not 
substantial changes have been made to hw. So I'm hoping copying my 
existing windows vm files to a fedora vbox environment will give me 
similar results as long as I follow the same approach should the need 
arise.


I've never had the need or inclination to virtualize a hardware 
installed Windows environment since I've always had enough legitimate 
Windows licenses to use or play with so I don't know how that impacts 
Windows activation. However I would not need to take that approach

In some cases you need to replace failed hardware with the same model, 
which might be difficult to do. MD raid is very hardware agnostic. Unless 
you buy high end gear you may end up using effectively proprietary 
software raid. The two main advantages of hardware raid are that it can 
be shared with Windows and there may be less traffic on your bus.

Hello,

I've been using Fedora inside Virtual Box on a Windows 7 host for a 
few years now so I can learn Fedora / Linux before taking the plunge 
and unplug from Windows more permanently. I think I'm ready to take 
the plunge and build a new desktop with Fedora 24 being my primary os 
and at most run Windows (should I need it for some reason) inside a 
VBox vm. I suspect running Fedora inside a vm is really different than 
running it right off the hardware like changing a hdd controller with 
a mouse click is much faster & easier than swapping a cable and/or 
setting or adding an adapter so I'm trying to do my homework before 
spending $.


My question is: what hardware would someone recommend for building a 
non-gaming high-end desktop? About the only non-negotiable element are 
my 2 30" dell u3011 monitors both running at 2560x1600. Since I'm a 
day-trader I need really good color & resolution for my trading charts 
but things like a high frame rate for gaming are not necessary. I have 
no amd / intel cpu preference - just 8 cores preferably and probably 4 
ram slots on a mb since I don't want less than 32gb ram. Recently I 
saw someone indicate nvidia graphics are not linux friendly and since 
that's what I've always used on my builds an alternative is needed. 
I've had really good results with Gigabyte mb's but am willing to try 
another brand. I'd also like to use an ssd hdd so does Fedora support 
sata3 or even sata 3.2 well? Am I correct in thinking ddr3 or ddr4 or 
ram specs of any kind (latency) are pretty much irrelevant and Fedora 
would support all such hardware? Does Fedora have issues with hardware 
raid which I usually use? Does Fedora care about 3 or 4 channel ram 
configuration? Not being a gamer I don't use SLI but since we're on 
the subject about compatible hw...does Fedora / linux / open-source 
have any capable sli graphics cards which work well and easily?


If someone has built an entire system like this recently would you be 
willing to share your component build list? Or if you have a graphics 
card which installed easily and would support my resolutions would you 
mind sharing it? If someone was frustrated with a particular component 
would you mind sharing what to steer clear of?


I would prefer to avoid the click & pray approach to component 
selection so I'm asking what has worked well for others...or what was 
problematic.


Thanks for any advice & feedback.

An alternative is a two-hard drive method.  Remove current drive,
install new one, install new system.  Add prior drive back in, but boot
from the new one.  Copy over config files from the old drive, or just
mount its home directory as your new /home.

It gives you a clean install, a safe install (no data can be lost if
there's none there), and a quick restart using the system option.

You may wish to check out a large Lenovo luggable laptop, their 
17.3-inch ThinkPad model P70.  Your choice of either its Core i7 or its 
Xeon processor can drive a pair of 4K monitors, a pair of SSDs, a hard 
drive, and removable storage from 64GB ECC RAM. You can move around your 
display environment with a trackpad, arrow keys, or a red joystick 
button in the keyboard. A fingerprint reader may hinder unauthorized 
access, a keypad facilitates numeric entries, and a color calorimeter 
allows periodic screen sanity checks. Good connectivity with other 
devices via in-built ports and an available docking station suggest 
computing environment cohesion. Since within a particular configuration 
its components are chosen for one another, it's possible to review a 
particular set of choices as a unit. The resulting reviews have 
generally been favorable, and your search engine can take you to them 
on-line. Some current concern remains about Linux driver status for the 
track pad and the calorimeter, but these issues may be resolved with 
more development time. An extra battery or two, and an extension cord, 
might be useful travel companions. Though not inexpensive in the 
suggested configuration, it may provide the useful flexibility that 
justifies its investment.

that is a simple solution.

another is to categorize email by type, or by year and month. all 3 of
which i had considered recommending, but considered it a waste of time
because i felt that anyone who is backing up an Inbox with over 30 MB
of emails is someone who is too lazy to create filters to sort emails
to a classification, even tho i did make comment on doing such.

sort filtering is an easy process to set up and maintains a much neater
storage of emails. also, by archiving sorted emails every 3, 4 months
keeps active email folder files in a state that can be easily and
effectively maintained by thunderbird and by user.

when i did installation, service and maintenance, i showed all clients
how to set up filters and archiving of emails by year and month, which
must be very reliable because i have yet to hear from any of them with
a problem of doing such. there have been a few that i have been
contacted by, but it was for ways to make minor changes, not problems.

lazy is as lazy does and lazy does create problems.

Mainly that it adds cost and still requires specialized drivers because
it often means proprietary formats which may not be well-maintained.
OTOH it may allow hot-swapping, depending on the model. Software RAID
is generally more flexible and on a modern system doesn't have a high
impact on performance.

Since the capability is built into many motherboards these days it seems 
more straightforward to me to control mirrored redundancy outside of the 
OS. I have no personal experience using redundant software raid even 
though I know Windows 7 supports it so I think it's just a matter of

No idea what you mean by SLI.



It's called the Scalable Link Interface capability built into some 
graphics cards where you can slave 2 (or more) graphics cards together 
and combine their gpu processing power for more a responsive graphics 
interface.  It's really nice for those who need it.

I have been doing a fresh install (/home/is on a separate parition, so I 
do not reformat it) for 4-5 years now. I use the server install iso and 
a kickstart file to do the initial setup then use rex from my primary 
computer to make all the changes I want after the initail install and 
the computer is rebooted. This includes updating the system and I am 
done in about 1.5 HOURS. If I upgrade all computers at the same time the 
rex program can be run on all computers at the same time. So updating 
more computers does not take any more time.


Using kickstart I put the standard install on then in the %post section 
I use dnf to install x11, xfce, libreoffice and any other packages I 
want. Also, I do some configuration as well (iptables, resolv.conf, etc).


Kickstart and rex are fabulous and are well worth learning.

 which would have increased the size of the backup by 30+ MB,
 and I got the following warning message:

 The folder Inbox.Bkup is full, and can't hold any more messages. To make 
 room for more
 messages, delete any old or unwanted mail and compact the folder.

 So, I still cannot figure out why every other app can handle BIG_FILES,
 but TB cannot.

The issue has nothing to do with "unsigned 64 bit file sizes" or the ability of 
TB to work
with large files.

The issue is simply that the developers "failed" to find all the instances in 
their code
which checked the file size prior to performing an operation. 

As I've mentioned, TB can work with files larger than 4GB.

You can manually get around the issue of not being able to add to large files.

With TB stopped, you can simply "rm" the folder's associated .msf file (the 
index file)
and then "cat somebox >> TheLargeBox".  Then start TB again.  When you open the
TheLargeBox folder the .msf will be rebuilt (it may take some time) and the 
messages will
have been added to TheLargeBox folder.

NVidia is quite well supported, especially if you don't care about
gaming, however you'll get some discussion about whether to use the
proprietary (binary) drivers or the free Nouveau ones. I use the former
(via the akmod system) but it's your choice.

Why do you use hardware RAID? There is little or no advantage and some
disadvantages in doing that. Software RAID works extremely well on
Linux.

No idea what you mean by SLI.

AFAIK yum upgrade and yum update have been the same for a very long
time. In any case, fedup is no longer recommended and dnf is now the
preferred option both for installation and regular updates. I've been
using it for a year or so without problems, including the last two
Fedora release upgrades. I don't think dnf and yumex talk to each other
much so I never use the latter.

I'm a little unclear on what your exact problem is. The Fedora page has
multiple download options, not just Live media. I haven't actually used
a Live download in several years.

Hardware Suggestions for Desktop Fedora

[Drew Samson]

Hello,

I've been using Fedora inside Virtual Box on a Windows 7 host for a few 
years now so I can learn Fedora / Linux before taking the plunge and 
unplug from Windows more permanently. I think I'm ready to take the 
plunge and build a new desktop with Fedora 24 being my primary os and at 
most run Windows (should I need it for some reason) inside a VBox vm. I 
suspect running Fedora inside a vm is really different than running it 
right off the hardware like changing a hdd controller with a mouse click 
is much faster & easier than swapping a cable and/or setting or adding 
an adapter so I'm trying to do my homework before spending $.


My question is: what hardware would someone recommend for building a 
non-gaming high-end desktop? About the only non-negotiable element are 
my 2 30" dell u3011 monitors both running at 2560x1600. Since I'm a 
day-trader I need really good color & resolution for my trading charts 
but things like a high frame rate for gaming are not necessary. I have 
no amd / intel cpu preference - just 8 cores preferably and probably 4 
ram slots on a mb since I don't want less than 32gb ram. Recently I saw 
someone indicate nvidia graphics are not linux friendly and since that's 
what I've always used on my builds an alternative is needed. I've had 
really good results with Gigabyte mb's but am willing to try another 
brand. I'd also like to use an ssd hdd so does Fedora support sata3 or 
even sata 3.2 well? Am I correct in thinking ddr3 or ddr4 or ram specs 
of any kind (latency) are pretty much irrelevant and Fedora would 
support all such hardware? Does Fedora have issues with hardware raid 
which I usually use? Does Fedora care about 3 or 4 channel ram 
configuration? Not being a gamer I don't use SLI but since we're on the 
subject about compatible hw...does Fedora / linux / open-source have any 
capable sli graphics cards which work well and easily?


If someone has built an entire system like this recently would you be 
willing to share your component build list? Or if you have a graphics 
card which installed easily and would support my resolutions would you 
mind sharing it? If someone was frustrated with a particular component 
would you mind sharing what to steer clear of?


I would prefer to avoid the click & pray approach to component selection 
so I'm asking what has worked well for others...or what was problematic.


Thanks for any advice & feedback.

Drew

Can you look at xfwm4-tweaks-settings -> Compositing

and see if enabling that "fixes" the issue? 

Or if it's enabled, you could try disabling it. It seems like a
compositor related bug to me.

It does sound like a very good way for those who can use it. 
Unfortunately for me, I lose out at "virtual machine." I know what one is, 
and even had one once (set up by an Alpha Technoid friend) 

Thanks for the clue, though. If I ever get far enough into 
virtuality (as I should, for topo map purposes), I'll remember there's a 
way to use it for upgrading, too.

[Tom Horsley]

The path I always use for updates is to install a virtual
machine, get everything the way I want it, then guestmount
the virtual image and rsync it to a hard disk partition where
I'll boot it.

Just need to fix any UUIDs and /dev/sdX that appear in
grub.cfg and fstab, then make a "configfile" entry in
your existing grub.cfg to point to the new one.

After you get the new one to boot, you can run
grub2-install and boot directly to the new partition.

(You also need to turn off selinux or force a relabel of
the whole new partition you just copied, I just leave
selinux off so I don't have to constantly fight it).

The great thing about this install technique is that I
never have to take my system down till I'm ready to
boot the new partition.

Correction: due to Amazon's confused marketing the tablets are actually
called Kindle Fire. However they are completely different from what is
usually called the Kindle.

You appear to be talking about the Amazon Fire tablet. The Fire is not
a Kindle. I've had several Kindles (currently using a Voyage) and none
of them have an app store, run a browser called Silk, or mention
Android anywhere in their documentation or system information. They
