Ah good, it would be nice to update to 2.6.28 :-)

Yes, it's required.  AUFS is used to provide a writable root file system.  The
CD won't boot without it.

aufs-20080508.tar.bz2 is an export of the AUFS CVS repository.  Also, it's for
aufs1 - aufs2 is the next generation implementation.  I don't know how stable
aufs2 is.

We currently build aufs1 as a external module.  However, the aufs2 release
(aufs2-base5) only contains a patch to the kernel source tree, and apparently
doesn't support building as an external module (according to
http://aufs.sourceforge.net/README.aufs2).  So we would have to build one
aufs-utils package, and the module itself as a kernel patch.
