[ANNOUNCE] Ubuntu kernel tree

[ANNOUNCE] Ubuntu kernel tree

[Ben Collins]

Some people may have noticed the new git tree located at:

rsync.kernel.org:/pub/scm/linux/kernel/git/bcollins/ubuntu-2.6.git

This tree will directly reflect the Ubuntu Linux Kernel that is available
in our distribution (along with build system). First use of this kernel
tree is slated for Dapper Drake (Ubuntu 6.04), and will stay synced with
the just released 2.6.14(.y).

There are several reasons for making this repo available on kernel.org.
Primary reasons include a more open development model, better visibility
with the kernel developer community, and to make the kernel available to
other distro's who may want to base their kernel off of ours.

Primary goals include:

* A kernel geared toward a real world Linux distribution, supporting
  drivers and subsystems that end users need. You will find a lot of
  external drivers in our tree, that for whatever reason, are not included
  in the upstream kernel. We hope that including these drivers will give
  users a one-stop kernel (no downloading and compiling external modules),
  and also provide much needed testing for modules hoping to be included
  into the mainstream kernel.

* Real world configurations. We will provide default kernel configs for a
  variety of architectures and system "flavors".

* Any feature and/or driver included will attempt to be configurable. That
  is, if you don't select to compile it, it will not cause any significant
  changes from the stock kernel we are using at that point.

* Open development model. We want to be as close to the kernel community
  as possible. Integrating ideas, getting feedback, and causing as little
  havoc as possible :)

No, I hadn't. But suddently the comment Mark made recently that the
Ubuntu kernel is available from kernel.org makes a lot more sense :-)

There was me thinking WTF? But I can see it was just a secret plan for
world domination all along.

Will you be providing patches against 2.6.14 for those that don't use
Ubuntu proper (using pure Debian here), but might want to give some
feedback on other kernel trees?


Thanks, Rogério Brito.

Nice.

Do other distros publish their trees anywhere? It would be handy to collect 
links and publish them in an article on distrodev.org or some place like that.

There's a really cool one over at http://www.kernelnewbies.org/ and
perhaps there could be one on kernel.org if the powers that be thought
that we a good idea (Wikimedia perhaps?).

Heh, I'm interested. We were thinking about using git for internal
suse kernel trees, but we thought it would not work, as we need more
something like quilt. Do you really use git internally, or do you just
export to it? If git is usable for distro develompent... that would be
good news.

Does this include the various closed source drivers that you include in
your distro releases?

The FC kernel trees rpms and source rpms are distributed from the fedora
site. 'Production' kernels go to the updates directory, others which are
intended for testing go to the update testing directory and may or may
not work wonderfully.

RHEL kernel source trees are also on redhat.com, although I suspect they
are of somewhat limited interest to most of the development community.

Source RPM's will just contain a Linux kernel tree with your patches already 
applied, right?

Is there an easier way to see what redhat/fedora have patched in, short of 
finding the closest vanilla tree and using "diff"?

That's a troll, Alan. .deb contain exactely the same things.

Of course not. Its an rpm file. RPM files contain a set of broken out
patches and base tar ball plus controlling rules for application. It's
rather more advanced than .deb sources.

Some packages use dpatch and related tools like this, and give you a
pristine upstream tarball and broken-out patches, but it is not
supported at the level that RPMs do---which is to say, in the core
tool.

Seriously, I pulled apart a whole lot of RPMs when I was doing the
first real (libc6) port of Debian to the Alpha in '96, and it was a
lot easier than dealing with the generally mashed-together patches in
a debian package's .diff.gz.

No, he's right.

The changes a package maintainer does in a .deb are shipped in one big 
diff containing all the differences between the pristine upstream 
sources and the tree used for building the package.

There are now ways how to arrange the patches in a way that they are 
visible as separate patches inside the unpackaged source tree used for 
building the package [1], but if all you are interested in is to get the 
patches applied against the upstream sources RPM is still superior
(even on my Debian system mc can extract the patches as if the RPM was a 
tar file).

That's only right in the simplest form. However, the debian kernel and a
huge portion of other complex packages contain a debian/patches/ directory
that gets applied at build time. Each patch is broken out seperately, with
description embedded in the patch.

Prior to this we were using baz (arch derivative), but all the patches
were still applied at build time.

We're giving git a go just to see. It's all being done right there, I push
directly to master.kernel.org (and also mirror it to a local machine where
ubuntu devs can make better use of it).

I don't have anything to do with the restricted modules package found
outside of our main distro tree.

I think over time, a set of patches and a clean kernel tree to apply
them to, is easier to handle.  Especially with such excellent tools
availble to do this now (like quilt and patch-utils).

But good luck with this, it will be interesting to see how long you can
handle maintaining the kernel in this manner.
