Fedora 10 feature owners--rescue your unfinished feature pages!
John Poelstra reminded everyone that the feature freeze for Fedora 10
is coming soon, and that feature owners need to get their pages updated
to ensure that the features that belong in F10 get in, and that the
features that need to be deferred to F11 are deferred. "Please complete
this as soon as possible so that we can prepare an accurate beta release
announcement. FESCo will also be reviewing the complete feature list at
its next meeting on Wednesday, September 17, 2008, and determining which
incomplete features should remain."
Updates to Fedora Packaging Guidelines
Tom Callaway announced the most recent set of revisions to the
Packaging Guidelines, including including Haskell, Lisp, and several
other areas. For the full announcement, read the link below.
Fedora 10 and translations: String freeze and repackaging
Dimitris Glezos reminded us "that shipped packages for which Fedora
is upstream for are string frozen since the Beta freeze of September 11:
no translatable strings can be added or modified for Fedora 10."
Fedora intrustion update
Paul Frields issued his latest updated regarding the Fedora security
breach that has been news during the past few weeks. "Work on the Fedora
infrastructure has returned to normal at this point. Updates are once
again available for Fedora 8 and Fedora 9, our current releases, using
the new package signing key we've implemented."

=== Tech Tidbits ===
Warren Togami announced the creation of a new list for
NSPluginWrapper. "NSPluginwrapper Development discussion with the goal
of isolating issues and collaboratively working on solutions should go
on this list. There was some interest from other Linux distributions and
even Adobe to cooperate on the future of nspluginwrapper
Jesus Rodriguez announced the release of Spacewalk 0.2, the
open-source upstream for Red Hat Satellite. There is a list of features,
enhancements, bug fixes, and credits on Jesus' blog.
Greg DeKoenigsberg helped the OLPC folks recruit volunteers to be
part of their growing infrastructure team. "OLPC builds a lot of
packages. They are looking to set up and maintain an infrastructure that
will allow them to meet their own unique packaging needs. They need a
volunteer with a strong understanding of the Fedora packaging process --
one who either understands koji now, or can learn to understand it in
fairly short order."
My favorite Planet post this week came from Fedora Board member Matt
Domsch, and it is worth people's time to read the entire post, to gain a
lot of insight into how Fedora's mass rebuilds work, and what triggers
"One challenge to self-hosting a project the size of Fedora (now with
about 6200 source packages) is dealing with the interdependencies
between packages. When a major component, such as the compiler or an
often-used library, upgrades to a new version, you should rebuild all
packages that depend upon that major component, to ensure they continue
to work. Often, simply re-compiling or re-linking each package using the
updated compiler or library is all that is needed. In some cases though,
applications which once built, no longer do - bitrot has set in."
Tom Callaway wrote a lengthy post about the Mozilla EULA controversy,
which reared its head again this week in the context of Ubuntu and
Mozilla. However, Fedora dealt with this problem several months ago, at
the end of the Fedora 9 release cycle.
Spot's entire post is worth reading, as is the commentary that follows
it. Here is one excerpt:
"[The] goal was always to ensure that we could walk away with license
terms from Mozilla that:
1. Permitted Fedora to continue using the Firefox trademarks 2. Clearly
upheld the MPL as the valid software license terms for the Firefox
binaries and source (not just for Fedora, but for everyone) 3. Meet the
criteria for Free Software 4. Are presented to the user in a
non-obtrusive, non-clickthrough agreement way"
Anthony Green wrote a post that referenced SGI's alteration of its
Free B license, which has long been a thorn in the side of various
=== Events & Ambassadors ===
The North American Fedora Ambassador Day is coming up at Ohio Linux Fest
in October, and there were a few posts about it on Planet this week.
Brian Powell gave an update on the organization, saying:
"There have been quite a few discussions and meetings recently in
regards to FAD planning. There has been a lot of good progress and great
ideas coming out of these. With time getting close, we are looking at
finalizing the Agenda and Schedule for FADNA shortly.
If you are a North American Ambassador I would ask that you take a
moment to look at what we have come up with so far and a 'tentative'
schedule of events located at the FADNA2008 wiki page. If you have
anything to add feel free to do so."
Additionally, Karsten Wade wrote a post about strategies for handling
remote meetings, and making a physical gathering of a small number of
people into a larger meeting that remotees can attend and still get
value out of, whether that attendance is via IRC, telephone, or
something collaborative like gobby.
"Think about your sessions and how it can help to interact with the rest
of us. I recommend a minimum of: live video feed, live audio feed, and
IRC, Gobby, and wiki editing projected on the wall. We can also keep a
VoIP conference room open, but my instinct is to limit the flow on the
incoming voices by subject matter. Beyond that recommendation, a live
IRC and wiki-based abd/or Gobby note taking with many laptops in the
in-person session is the bare bones, with regular usage of
David Nalley wrote up a trip report for Linux Demo Day in Charleston,
SC. "About 60 people showed up. Charlestons LUG is relatively new, and
this was their first event. They seemed very pleased. I handed about 30
LiveCDs out and talked with a number of Fedora. In addition I spoke to
2-3 people who were intrigued with contributing to Fedora in one way or
another. Ill be following up with these individuals." This is a great
example of an event -- low cost, but high touch!

Plug and Run Fedora on a TOSHIBA A300D laptop
This post recounted some adventures with Fedora and a very tricky
laptop. It is always good to know about such success stories. Some
laptops do not even start GNU/Linux at all! But this one seemed to work
pretty well with Fedora.

=== Removal of non-X Consoles (continued) ===
The furore over the future removal of text-mode consoles (see FWN#144
"Non-X System Consoles to be Removed") continued throughout the week.
The original thread saw some support for the idea expressed by
Nicolas Mailhot on the basis that "[...] non-X-console input is a mess
[...] font support has fossilized, and support for modern high
resolution screens is severely lacking [...]" Nicholas was especially
concerned with the maintenance burden imposed by the text-mode
console "[...] as someone who is an upstream maintainer for my language
of some of the bits the console use[s]."
Upon being pressed by Dominik Mierzejewski for evidence of a lack of
proper maintenance Nicolas listed a series of problems including the
stagnation of the console layout database and the console font set.
Dmitry Butskoy begged to separate the concepts of "console" and
"serial tty" and also for the retention of the text-mode console.
Dominik promised to try to find a colleague to shoulder the maintenance
burden but Nicolas had already given up in disgust. In response
elsewhere to Seth Vidal's argument that the text console did no harm and
should be left alone Nicholas expanded on the maintenance costs of
"all sorts of packaging rules designed to avoid hitting console
limitations and problems" and bugs filed because of the confusion caused
by two text stacks.
Les Mikesell got to the heart of the problem when he asked "I think
I'm confused by the term 'non X consoles'. Is that something different
than the native text mode you see before X starts?" He also recommended
using FreeNX/NX instead of using the console. Nicolas responded that
there were "[...]two different things. A VT to which you can attach an X
session, a serial port, a remote SSH, mingetty... and the software stack
used to display locally the VT text and collect user input." Nicolas saw
the "low-level VT bit" as fundamentally sound but the "current console
software stack" as "rotten." Les sought further clarification of
this distinction between "[...] the low level part that works in
character mode and expects some hardware to supply and render the fonts
[...]" and "[...] software other than X that renders custom fonts[.]"
Denis Leroy wondered if there was "[...] an X-based mingetty
replacement actually exists ? Something that's proven to be sufficiently
fail-safe (will work even with half-broken X configurations and such?)"
and although Nicolas did not know of one he speculated "[...] as
soon as much of the hardware pocking is moved from xorg to the kernel
and X can be run as a normal user "X-based mingetty replacement" will be
just running a x term fullscreen in an autoconfigured X instance. Of
course one could theoretically write a much lighter solution using only
freetype (cairo, pango?) and an xkb-config parser." Denis's concern
seemed to be that often a Ctrl+Alt+F1 to mingetty was the only way to
kill hanging desktop applications. Colin Walters suggested making
"[...] Ctrl-Alt-Backspace just break server grabs instead of killing the
server (and of course fix the bugs in the apps that hang while holding a
There were multiple expressions of disapprobation often coupled with use
cases. Some of these led Chris Snook to exclaim "Unless I've missed
something huge, virtual terminals aren't going away. What may or may not
be going away is the x86 video BIOS text mode, to be replaced with a
kernel framebuffer, which precludes the use of console fonts, which very
few people ever mess with. The console itself will remain. Someone
please correct me if I'm wrong." [[DaveAirlie|Dave Airlie] confirmed
this understanding and added "[...] vga text mode will not be enabled by
default, you will need to pass nomodeset if you want to use vga text
mode. Welcome to the 1990s." Alan Cox made the correction that
framebuffer console support fonts but that framebuffers did not work on
all machines, screen reader technology and remote management cards.
=== OpenVPN and resolv.conf ===
Ahmed Kamal asked for help in scratching an itch and started a
concise, meaty thread. His particular problem was that he wanted to
overwrite /etc/resolv.conf with new DNS servers obtained over a vpn
tunnel, this is apparently done automatically in "Windows".
The suggestion to use NetworkManager was made by Paul Wouters and Dan
Williams agreed and added the explanation that it "[...] mediate[d]
between services [including PPP, PPtP, DHCP, openvpn, and vpnc] that
need to update your DNS information." The alternative is that each
service needs to handle /etc/resolv.conf itself.
The idea of a default caching daemon was floated by Simo Sorce. As he
envisioned it, the services/tools, such as OpenVPN, would "[...] tell
the caching daemon which IP ranges and which domains their provided
forwarders should be consulted for. All dynamic so that as soon as one
daemon goes away, the caching DNS will notice and revert queries to the
default DNS.} Nils Philippsen agreed heartily and added that
"[i]deally, it should be something which isn't restricted to class A/B/C
like reverse DNS (seems to be), but which would route DNS requests based
on arbitrary domain name or IP-range criteria to the desired name
servers" and Paul Howarth provided the further reason that changes to
/etc/resolv.conf are often not picked up by processes. This latter point
spawned a discussion on the demerits of the glibc stub resolver (which
is too simplistic) and the consequent use of the deprecated
gethostbyname in individual applications. Dan Williams recommended using
lwresd (a stripped-down, caching-only nameserver available to clients
which use the BIND 9 lightweight resolver library) or for more complex
setups a local caching nameserver. Although Simo Sorce disagreed with
Dan that many applications were simply using gethostbyname he agreed
that "[a] caching nameserver that can be instructed what to do when
conditions change is what we really need."
Ahmed asked whether dnsmasq or other daemons were able to "[direct]
name resolution to specific servers according to IP ranges and/or domain
names, with the option of adding/removing servers on the fly?" and
Richard W.M. Jones confirmed that this was indeed possible. Adam Tkac
suggested that this could be done with view statements in BIND and
the gauntlet of how to do this for CIDR and domain names was thrown
down by Nils. A detailed sub-thread followed which indicated what
while possible it was not pretty.
Adam Tkac shared the information that his TODO list includes the
addition of NetworkManager support to BIND and Simo Sorce explained 
that nscd was not a solution for a local caching nameserver "[...] as
not all type of queries can be fulfilled by the glibc interface. For
example SRV/TXT records ... Also nscd is not smart enough to understand
network condition and adapt it's behavior." Simo agreed that it would be
nice if "[...] bind could consult different DNSs based 1) on the DNS
name to be queried, and B) the reverse IP to be queried" so that on slow
links only the necessary queries would be directed through the VPN.
=== Fedora 10 Feature Owner Request ===
John Poelstra requested all those owning a Feature to take some
actions on their feature page so that the beta release notes and
announcements are accurate. He provided a list of twenty one feature
pages which "have not been updated since the Feature Freeze on
2008-09-11 and/or are not 100% complete."
Kevin Kofler was among those who had been watching the progress of
OpenChange (see FWN#133 "Help Wanted: Samba4, Heimdahl, OpenChange")
and noted that due to the decision of Andrew Bartlett to orphan
the feature it needed a new owner if Fedora 11 was to offer OpenChange.
Another of the listed pages was that for the Echo icon theme and Luya
Tshimbalanga asked if he should add a release note to the effect that
echo was now the default. Rahul Sundaram confirmed that this would be

=== system-autodeath Becomes Reality ===
Seth Vidal announced that he had implemented his previously discussed
(FWN#140 "System Autodeath") idea to automatically remove networking
capabilities from machines which lacked system updates. The intent is to
prevent non-maintained machines from being exploited.
Seth implemented the concept as a daily cronjob which tests a configured
"death date" against the current time. For the week leading up to the
"death date" log messages warn that on the specific date the default
route will be deleted. He requested feedback and improvements.
Matt Miller was content but suggested beefing up the manpage with
details of the consequences of removing the default route. Seth noted
that he was happy to accept patches.
A fraught note was introduced when Stephen Warren declared that if
this were a default then, in combination with the proposed textconsole
removal (see this FWN#144 "Removal of non-X Consoles (continued)") and
the modesetting changes, he was thinking about switching distros.
Rahul Sundaram responded that modesetting was going to be a feature
of all distros soon and the conversation veered into explaining that
the replacement for RHGB, named "Plymouth" had a sane text-mode fallback
for unsupported chipsets. As much of Stephen's angst was due to a
perceived abandonment of those using non-Free drivers Rahul pointed out
that the nouveau drivers might work. Richard Hughes listed 2-D and
xrandr as supported with kernel modesetting coming soon due to Maarten
Maathuis's work. He warned: "Don't even try 3D yet. It does work, but
only if the moon is waxing, and your pet cat is called Oliver."
Back on the main topic of the thread Seth stated that
system-autodeath was not intended to be part of the default install:
"This is just a nicety for sysadmins or local-respin maintainers who
would like to put a dropdead date on their releases." In response to
Stephen's recollection Seth also stated this point clearly. A
general disagreement with the idea of exposing such a feature was
expressed by James Hubbard on the basis that the user should be
forced to change a config file to prevent against accidental
=== Fedora Not "Free" Enough for GNU? ===
A long-running thread which was started on 07-09-2008 by Michel Salim
continues to attracted some heated discussion over the fact that Fedora
is not recognized as a 100% Free software distribution by GNU although a
derivative named "BLAG" (see also FWN#139) is recognized as FLOSS.
The central stumbling block seemed to be best stated by Gregory
Maxwell as "[...] Fedora doesn't yet strip the binary firmware provided
by the Linux kernel (and still provides some re-distributable binary
firmware in other packages, the microcode package and alsa-firmware I
think)." Gregory described the situation as unfortunate due to both the
lack "[...] of acknowledgement it deserves, and the FSF is indirectly
promoting Ubuntu, a distribution which is, as far as I can tell, a
primary driving factor in new users using and depending on proprietary
software." This latter being a reference to the recognition of gNewSense
There had been previous very heated threads on this subject (during one
of FWN's holidays) centered around the efforts of Alexandre Oliva to
produce a "kernel-libre" and the interaction of this project with other
efforts and approaches within the kernel community. David Woodhouse
added the excellent news that "We are almost at the point where we
can do a spin which remedies [the difficulties of stripping out the
non-Free firmware]." He explained that soon a completely separate
package instead of a sub-package of the normal kernel build will allow
others to produce alternative packages of firmwares for which source
code is available. Tom Callaway was worried that there was still
firmware entangled in the kernel source code and noted the need for an
audit. Rahul Sundaram supplied a link to a Debian inventory of
Other interesting points in the discussion touched on the rationales
which have been often advanced for refusing to supply source to
firmwares. These involve regulatory compliance (often for radio
devices). Alan Cox was suspicious of such arguments based on the
history of examples such as ISDN code which "[...] was approved. You
could change it but then it became unapproved and not permitted in some
countries." He described this as a racket run by the phone companies
which imploded once the need to ensure robustness became important (due
to terrorist threats.) Ignacio Vazquez-Abrams listed some of the

=== 2008-10-14 Declared Fedora 10 Package Translation Deadline ===
The last date for submission of translations for Fedora 10 packages was
announced as 2008-10-14 (Tuesday). This announcement was made after
an unanimous decision by the Fedora L10n Steering Committee (FLSCo)
members. The last date for the translation of Documents remains as
A request for rebuilding of packages post the translation freeze date,
was also made to the @fedora-devel-announcement list.
"Maintainers of the above packages need to put a reminder to issue a new
build *later* than this date and before the Development Freeze of 21/10.
The closer to the development freeze the rebuild takes place, the better
for our translators. If you have not received any translations since the
last build, a rebuild is not necessary."
=== Renewed Call for Volunteers for the L10n Infrastructure ===
Another call was made at the FLSCo meeting held[ on 16th September
2008 seeking volunteers for the Fedora L10n infrastructure. The
earlier call was made in April 2008.

Pursuing the declared goal of having the new Echo icon theme ready to be
used as a default in Fedora 10, Martin Sourada and Luya Tshimbalanga
continued the development and posted updates, while gathering
feed-back and improvement proposals on @fedora-art. Martin even
created an animated demo "also prepared animated gif (slideshow) so
you can see all the icons in one batch" and blogged about it.
=== Freedom for a Game ===
Nicu Buculei relayed to @fedora-art a request from the Hans deGoede,
of Games SIG fame: the Project: Starfighter game, which used to be
included in Fedora, was discovered to have some non-free graphic files
and needed free replacements for them. Erick Henrique offered his
help "I go to unpack the archive starfighter.pak and to study a form of

After upgrading virt-manager to 0.6.0, Maikel Dollé received the

Shigeki Sakamoto followed up on a previous request for comments on
a patch, submitted by same, which works to allow the migration of

on the sanity checks in libvirt.
Live Migration Sanity Checks were recently discussed on @libvir list

=== Fedora Xen List ===
This section contains the discussion happening on the fedora-xen list.
==== DomU Network Interface Problem Leads to Discussion of HVM
Guillaume asked about a paravirtualized domU which did not show
any network interfaces. There was a suggestion made that this could be
due to a lack of HVM support in the host hardware, which isn't the case.
Paul Wouters cleared up such confusion by describing the main
virtualization techniques used in Fedora. Quoting:
* Xen hypervisor for para_virt guests does not need HVM.
Problem here is that Fedora 8 is the last release to support this
setup on x86_64, though work is in progress to add this support to
Fedora 9/10. Para_virt guests are booted via kernel= and rootfs
images, or via pygrub, which is just a wrapper for grabbing kernel
from bootable disk images.
* Qemu is a software emulator for various architectures including PC
It requires no HVM instructions, but it can use them if they exist
via the kernel "kvm" code. This is how Fedora9 does its VM's via the
libvirt and virt-install. This does NOT [sic] use or require a xen
* Xenner is a software emulation for the Xen hypervisor.
It requires HVM because it uses the kernel "kvm" code. The idea
behind Xenner is that you can run VM's based on kernel-xen kernels
(eg migration from Fedora8)
Paul went on to mention other virtualization technologies such as
VirtualBox/Vmx, lguest, uml, virtuoso, and openvz.
In another post Paul suggested that Guillaume's domU may have an
initrd which lacks xenblk and xennet, and pointed to a debate in the
FC6 era concerning the xenblk kernel module.

==== Access to CPU Flags ====
Ben Guthro needed to access CPU flags to determine if VMX features
were available, and suggested src/nodeinfo.c would be the place to parse
this. This however raised a concern that adding to the nodeinfo struct
breaks the API. Additionally, since this is an x86 specific change, Ben
wondered if it would be acceptable.
Daniel P. Berrange stated "any struct or API in
include/libvirt/libvirt.h is immutable to preserve ABI", and the API
shouldn't be specifically x86. Daniel did offer that the most likely
place for exposing CPU flags would be in the capabilities XML format.
Where PAE, VMX, and SVM flags are already exposed.
Ben noted that Xen will report those flags, but oVirt running KVM

reusable node info code".
