install f22 into btrfs subvolume won't boot
by Neal Becker
I tried it. It was not easy to figure out how to use anaconda gui to setup
install into a subvolume - but I got it done. I now have 3 subvolumes:
sudo btrfs subvolume list /
[sudo] password for nbecker:
ID 256 gen 1818627 top level 5 path home
ID 259 gen 1818478 top level 5 path root
ID 487 gen 1818625 top level 5 path root00
But if I try to boot with 1st grub entry, I get:
dracut-initqueue warning could not boot
starting dracut emergency shell
If I try to boot off the grub entry labeled 'rescue', it boots OK.
dracut says something about fixing initramfs.

BTRFS Question
by Javier Perez
Hi
I am just learning about btrfs on my home system.
How do I know what kind of options where used to create a BTRFS filesystem?
I installed F21 from scratch and I created a BTRFS filesystem on a HDD.
I think I created it with the "single" option.
Now I read that that is dangerous, I should have created it as one of the
raids if I want to have data redundancy and protection vs bit rot (which is
what I was looking forward to).
How can I verify it? Also, If I want to change it, can I do it IN-PLACE or
do I have to reformat/recreate the filesystem?
Thanks for whatever help/illumination you might provide. I am catching up
on btrfs, but I am not there yet.
JP

RFC: Multiboot Guide
by Pete Travis
Hi All,
There's regularly questions here, and around the internet (ie ask.fp.o)
about dual booting Fedora with Windows systems, or other Linux systems,
or OSX. To address the more common questions, the Fedora Docs team has
written a Multiboot Guide[1].
The guide is intended to help set up a multiboot system in a functional
way, or to help get to a more functional state if needed. For the most
part, we've tried not to make it intimidatingly complex, and I hope that
it will aid you in most multibooting situations.
As with all of Fedora's documentation, feedback from readers is crucial
to ensuring the quality of the work. Please use the guide, and if you
find questions unanswered or answers unclear, reply here or use the
'multiboot-guide' component of the Fedora Documentation product on
https://bugzilla.redhat.com .

Biting the bullet?
by Rolf Turner
I have finally reached a stage where I may have to bite the bullet,
grasp the nettle, screw my courage to the sticking place .... and
upgrade my Fedora version.
I am currently running Fedora 17. Which is of course antediluvian. But
everything I have seen on this list with respect to upgrading terrifies
me. Disasters seem to lurk everywhere and I haven't the skills to cope
with disasters. Nor do I have access to any support in respect of Fedora.
So, if you will bear with me, I'd like to start off with a preliminary
question:
The seeming necessity for upgrading arises from a pressing need to
upgrade "R" to version 3.2.0. When I try to build this version I get a
load of error messages (basically coming from gcc I think) like unto:
> connections.o: In function `gzcon_write':
> /home/rolf/Desktop/Rinst/R-3.2.0/src/main/connections.c:5469: undefined reference to `deflate'
There were also complaints about undefined references to inflate, crc32,
deflateEnd, inflateEnd, inflateReset, inflateInit2_, deflateInit2_,
compress, uncompress, and zlibVersion, many of which were issued
repeatedly. It finally gave up, saying:
> collect2: error: ld returned 1 exit status
People from the R-help mailing list said that the problem lies in some
"compression related" libs --- zlib, bzlib, liblzma.
I tried installing zlib and zlib-devel (using yum install) and was told
in both cases that my system was up-to-date. I tried installing bzlib
and was told there was nothing by that name. I then installed lzma and
lzma-devel (*that* seemed to work) but it didn't help. Same undefined
references problems as before.
It was also suggested that I try building R-patched. So I tried; no
help there either.
So: Can anyone suggest what I can or should do to overcome this problem
*without* having to upgrade?
Given that the answer to my preliminary question is "No", can anyone be
so kind as to provide me with a *recipe* for upgrading, expressed in
simple-minded terms that I can understand? Something of the form:
(1) First, do this.
(2) Second, do something else.
(3) Third .....
You get the idea. I'm afraid vague generalities would be of no help to
me, since I am a bear of very little brain and long words bother me.
(I know that step (0) is to make a backup of all my user files. Which I
know how to do and will do.)
A specific question, I guess, is: Do I use yum for such an upgrade?
(And if so, what is the syntax?) Or do I use fedup? (And likewise, what
is the syntax?)
If no-one wants to write out a set of instructions for me (and
admittedly I can see that they may well not want to) can someone point
me at such a set of instructions somewhere on the web? Again, they
would have to be expressed in a very simple-minded way. ("Upgrading
Fedora for Dummies".)
Everlastingly grateful for any help that anyone can extend.
cheers,
Rolf Turner

C/C++ Compiler Invalidly Turning Warnings into Errors?
by Stephen Morris
I have a driver for a wifi usb device that I need to compile because
there are no drivers in the kernel, which has been obtained from the
vendor of the device. When I attempt to compile the code the compile
fails on the grounds that some warnings are being translated into
errors. From my perspective these errors should not be happening
because, when a debugging module wants to time stamp the build, that is
not an error and is perfectly acceptable. How do I get the compiler to
stop producing these errors. The messages I get are listed below.

F22 KDE How To Remove "Software Updates" Widget?
by Christopher Ross
In the Fedora 22 / KDE 5 task bar there is a "Software Updates" widget.
Where is the setting to remove that? It's inappropriate for arbitrary
end users to be be updating the system software on shared machines.
Many thanks,

Hi Matthew,
Looking forward to this release. I haven't read the release notes yet,
however I have a few questions or comments. If "read the release notes"
is the best answer, please feel free to say so :).

I'm interested in running SLC containers on Fedora hosts. Does any of
these packages facilitate that? What I understood so far is, it allows
me to run the latest Fedora containers in other places easily. Where
would one go looking for info for a need like mine?

I tried this a bit already, I like the convenience of having everything
aggregated together, however I'm a bit uneasy that a browser is the
interface. After all it is the most vulnerable application on most
machines. Are there other (safer) interfaces I can try, preferably on
the CLI? Am I being unreasonably paranoid? I'm really interested in
trying the multi-server bits. Any pointers?

Is this desktop agnostic? I use XFCE. I'm guessing it's some kind of
DBUS magic?

Collecting all the resources on RTD is a great initiative. Wonderful!

This question is probably off-topic here, but I'll ask anyway :-p. Does
this make a significant difference during development when I want my
projects to also compile with older GCC like 4.[89]?

This question is not exactly about FedUp. I find it strange that no
release so far has supported yum (or dnf now) as one of the upgrade
methods. And yet, I have had the most reliable upgrade experiences with
it since F12 or so! Any reason why this is the case? I think it is the
method that allows for the shortest of downtimes.
Thanks for the release. Looking forward to trying it!

How to figure out which package provides the "Fixed 16" font
by Ranjan Maitra
Hi,
I was wondering how to find out the package that provides the font called "Fixed 16" in Fedora 22. The font existed in Fedora 21. Installing the same packages in F22 that were in F21 has made this font disappear (actually, I fedup-ed and nothing font-related that I can tell was dropped or obsoleted.)
Many thanks,
Ranjan
