Are you sure you rebuild the linux26 kernel package? Only if you rebuild
the kernel after adding the aufs package you'll get the aufs module as
the kernel modules need the kernel to be there.

If the aufs module is there it should be preferred over unionfs.

Sure, this means it's selected (if the line starts with an X).

However, when you just build the aufs package you only get it's
maintenance tools (if any).

Due to the nature of the monolithic Linux kernel those add-on modules
require the whole kernel source tree to be around to compile. In T2 we
setup those third pary modules to be compiled when the actually linux
kernel is compiled (linux24, linux26 packages). So in order to get the
aufs file-system kernel module you need to rebuild your liniux26 package
(e.g. by Build-Target -job 5-linux26) to have aufs build along when the
kernel is build and the actual source code tree is available.
