[arch-dev-public] aufs / unionfs / aufs2

Okay, I received a few mails from Christopher Rogers who played with these filesystems and 2.6.29. According to his statements, he could get aufs2 to compile, but it only actually worked when he omitted the unionfs patch. Maintaining this patch mess has been a PITA, so I say we have a choice here: Choose one and drop the rest. I think aufs should not be considered, but only unionfs or aufs2. I don't use these, but the people who do should give some input on which one to choose.
