I can speak just for myself, and in my opinion it wasn't it.

At least Knoppix and Slax switched to AUFS even before the release of unionfs 2.0.
The switch was not due to missing features in unionfs, it was due to huge instability, for example simple filesystem operations freezed the whole computer, mmap support was completely missing or broken (until unionfs people incorporated the idea from aufs), and so on. Any single similar problem did not happen with aufs, which is used in Slax by hundreds of thousands of users.

In general, I need an union filesystem and I do not care if that is unionfs or aufs. But since I have very bad experience with unionfs (and I am not alone), and I have very good experience with aufs, along with all hundreds of thousands users of Slax, I wish aufs to be mainlined; because the code simply works, since its initial release, for many years.
