Subject: [PATCH] aufs2: Add recipe (to be cleaned up) to build AUFS2 as
 modules on a 2.6.27 kernel.

* This REALLY needs to be tweaked to pull out the kernel version used and build a suitable package for that kernel version with a generic 'meta' package that will pull in the right one. Not sure how that will work best.
