Welcome to issue number twelve of the Fedora News Updates. Fedora
Core 2 has been released, after over six months, and it's been a big
week for all of us. Updates here don't contain much more information on
the test3 release any longer, unless the issues still got carried over.
Happy reading!
Fedora Core 2 released
Fedora Core 2, dubbed Tettnang got released on the 18th of May, 2004
(two days ago). Read the
announcement,
and the
release
notes. Sporting a 2.6 kernel, GNOME 2.6 & KDE 3.2.2, with Xorg
6.7.0. FC2 also includes SELinux (not in enabling mode by default), and
XFce 4, as another window manager. IIIMF, which is great for CJK-input,
is also included, and requires a lot of testing in this release cycle -
FC3 plans on removing the other alternative by default.
Download the ISOs via a mirror near you, or use the
Duke torrent, or the newer
European torrent.
Remember to leave your client running even after downloads so that you
contribute via uploads to the other clients - this is what keeps the
torrents efficient!
Performance tuning the Fedora desktop
Will Cohen has been tasked with tuning the desktop to improve
performance, and
requested
for comments. Havoc Pennington stated what
Fedora
considers as the desktop, and also included some of the useful
tools one can use to identify desktop performance related issues.
Soeren Sandmann Pedersen talks about the two important properties of
profiling
CPU usage at the desktop level, with Will Cohen
adding
further to his comments.
Warren Togami chimes in mentioning the usage of an
-Os
rather than an -O2 optimisation on builds, further adding that
recent Fedora kernels are also built with -Os. The usual complaint of
the rhn-applet being a little hungry for memory came up, and Will Cohen
created some
interesting
statistics with regards to it. Alexander Larsson provides some
information as to how he's been doing
performance
testing on Nautilus, with the methods that he's been using, and
Soeren pops in recommending
speedprof.
In case people wondered if
preempting
in the kernel would help, it turns out that it won't.
After all the discussion, Will Cohen posted a
summary
of his findings. Excellent developer discussion, and I'm sure we
can only see better things coming out of the Fedora desktop.
Moving on from Fedora Core 1 to Fedora Core 2
There have been plenty of tips, and words of advice that people have
managed to stumble upon when the big task of upgrading their production
systems from Fedora Core 1 to Fedora Core 2. Here's an attempt at
collecting the lot.
- Seth Vidal has an excellent guide titled: Upgrading
from FC1 to FC2 using yum, and its filled with suggestions as well
as his experiences around it.
- Robert Day mentions that a backup of /etc will be good at http://www.redhat.com/archives/fedora-list/2004-May/msg02580.html,
while Elliot Lee says that after a backup, and an upgrade, if it provides
unhappiness, do a reinstall. Tom Mitchell mentions that a CD
upgrade shouldn't be too much of a hassle.
- The Unofficial Fedora Core 2
FAQ has been released. At this early stage its expected to change,
and more content is to be added; so if you think it deserves a new
entry, write to Max.
- Rick Chen points us to another resource, titled Fedora Core 2
Tips & Tricks, by Gregory Gulik.
- Fedora Tracker has
had a big update, and its
listed changelog is at http://www.redhat.com/archives/fedora-devel-list/2004-May/msg00568.html.
- Fernando Ribeiro has written a little utility to monitor how the
Fedora mirrors are doing: http://www.acert.pt/~fribeiro/mirrorwatch/?id=4.
Yay, pretty graphs!
- Jakub Jelinek has a little guide that mentions how to install
Fedora Core 2 from a hard disk, without burning any CDs, provided you
have a partition available at http://www.redhat.com/archives/fedora-list/2004-May/msg03696.html.
Fedora Core 2 not playing well with Windows XP partitions?
It turns out that the bug (
#115980)
is a result of a few subtle but key changes within the 2.6 kernel. A
certain functionality with regards to hard disk geometry has been
pulled out, as the kernel developers thought it would be better if
userspace utilities took care of this instead. The Bugzilla bug is
related to CHS geometry problems, which most likely stems from an error
within the parted utility, addressing the BIOS incorrectly. It turns
out that BIOS updates tend to fix problems for many users that have
been bitten by this "bug". On newer machines, this is basically
non-reproducible.
sg not required for regular CD ripping/burning
Seems a lot of people are complaining that they require the sg module,
but Arjan van de Ven has repeatedly stated that CD ripping or burning
does not require the sg module. In a statement:
The 2.6 kernel series provides a new
and much improved mechanism (called SG_IO) for applications that want
to send raw commands to storage devices, this includes applications to
burn CDs or to extract audio CDs. The packages in Fedora Core 2 have
been adjusted for this. For example to burn CD's with cdrecord you now
need to do:
cdrecord --dev=/dev/cdrom
or if you have more than one device
cdrecord --dev=/dev/hdc foo.iso
for IDE or
cdrecord --dev=/dev/scd0 foo.iso
for SCSI/USB
instead of providing the clumsy --dev=0,1,2,3,4 way of specifying which
burning device to use.
Firewire and Fedora Core 2
Alexandre Oliva has got plenty of information on what the status of
Firewire
support and Fedora Core 2 is currently. An excerpt of his document
is provided below.
Fedora Core 2 ships with a kernel
that's quite close to 2.6.6 and that, as such, has seriously broken
Firewire modules, so they were disabled to avoid problems.
In the text, you'll find information on how to install Fedora Core on a
machine that uses Firewire CD drives, and/or to Firewire HDs (in
section 1); install Firewire modules for use by the system after the
installation is complete (in section 2); build Firewire modules for
other 2.6.6ish kernels you might choose to install (in section 3); and
add modified Firewire modules (or any other modules, for that matter)
to the Fedora Core 2 install CD (in section 4).
Fedora SELinux FAQ updated
Karsten Wade has
updated
the
Fedora
SELinux FAQ. It now sports a table of contents for questions, has
the questions divided by subject, and the content is updated for Fedora
Core 2.
From the Fedora Legacy trenches
If you're a Red Hat 9 user, and want to get on the Fedora Legacy
bandwagon, Michael Schwendt has written up a fairly useful guide on
some pointers you need to follow at:
http://www.redhat.com/archives/fedora-legacy-list/2004-May/msg00123.html.
Though posted at the beginning of the month, there is a list of
packages that the Fedora Legacy project needs to complete QA on:
http://www.redhat.com/archives/fedora-legacy-list/2004-May/msg00049.html
if you're interested in helping out with the project.
Plans have started, to
drop
support for Red Hat Linux 7.2 and Red Hat Linux 8.0, soon, as
posted by the Fedora Legacy lead, Jesse Keating. Most of the responses
are positive, as Fedora Legacy lacks manpower, and this is seen as a
welcome change.
Fedora on your Mac/PPC
Jesse Keating writes:
I'm pretty separated from the
development work on PPC, I just use the resulting binaries that show
up. For the most part, FC2 (development) works very well on my
iBook. There are some niggly issues, such as resume from suspend not
working every time, and battery life is a bit sucky right now, but on
the whole it is very nice.
Yes, it runs, and there are quite a few running it already. There's an
IRC channel for Fedora PPC users, at #fedora-ppc. Another resource is
the
FC2
PPC Install Guide, and if you're stumped with bugs, there's a
Fedora
Core Mac (PPC) Tracker Bug.
Some more development issues...
- Jakub Jelinek has posted a bit about making NPTL the default
threading library in Fedora Core 3, as a step in phasing out
LinuxThreads. The thread is still unfolding, so catch it at http://www.redhat.com/archives/fedora-devel-list/2004-May/msg00617.html.
- Jon Orris has an extensive study of possible shared
calendar implementations.
- Seth Nickell has got a little note about menu
policies, for package maintainers. The rest of the thread contains
a bit of discussion with regards to it, and when there's a wiki he can
edit, it'll be online there.
Software
Firefox 0.8 and Thunderbird 0.6
Warren Togami has posted information about the Fedora.us project having
these packages available, and that they have been released. Read more at
http://www.redhat.com/archives/fedora-list/2004-May/msg04041.html.
Ximian Connector for Evolution
This made waves, as it allows Evolution to connect to an Exchange
server. The Fedora.us team have a package reading in
Bug #1590.
