They're removing dependency on AuFS because it's not enterprisey enough, but if compared to Docker (which, in my personal opinion, is very immature and lacks almost everything you'd expect from the container virtualization management tool except for the basic features, although there are, indeed, some workarounds for some cases) AuFS is granddad-level mature.

AUFS is what runs the dotCloud platform. The reality is AUFS is pretty amazing, and used in production, and stable and mature as you say.

But, having to require a patched kernel is a huge barrier for adoption.

AUFS will return as soon as possible as an option. It will just long term not be the default option.

Actually they're removing AuFS because it has awkward kernel dependencies and prevents Docker from running across all Linux distros. The move to device-mapper layers means Docker no longer requires a 3.8 kernel or an AuFS patch.

I haden't any problems with running AuFS on "stable" 2.6.x kernels (on Debian, Arch and Gentoo, and can't see why other general-purpose distros won't work) several years ago. I read, due to not being a part of kernel itself, it has problems with keeping up-to-date with very recent (3.10/3.12) kernels, but that's about it.

Not sure if enterprises wants to run the very bleeding edge software for sustainable mission-critical business-to-consumer yada yada.

Enterprises don't, but they often do want to run Redhat or Suse
