In my case - the PPC port - the ABS script would still need to be
modified since I still haven't sucessfully
compiled cvsup itself. Also I got offered a Subversion repository on
archlinuxfr.org and am happily using it.
From my experience there are lots of feature I definetely wouldn't want
to miss out on.
Since ABS only wraps around a few CVS pulls in the i686 branch I could
say that i have soemthing like ABS as
Package updating normally is done by first modifying the PKGBUILD,
building the package, test the package, then
upload the binary and finally commit to SVN after generating a new

How would you do that? Here is how I think it could be done (this
reflects the testing/xorg package for ppc),
sorry for the long interruption of the textflow. ;)

That is one possibility but as you can see it might get very messy if
other CARCHes come in as well.
Which makes me thing this is far from perfect.

What about current/os/$CARCH ? This structure has been there for ages
now in the binary repos.

Agreed, I'm all for merging the PKGBUILDs as far as possible. Though
someone still needs to come up
with an idea for architecture specific packages like bootloaders
(yaboot, quik, grub, lilo, pbbuttons etc.)
