If you compile from latest sourceforge version from the developer, it is surely OK. My concern was about the "correct" version of aufs.

"Essential" is of course a relative concept. As a new example, on Friday an error message appeared on R-help: http://www.mail-archive.com/[email protected]
A possible explanation, mentioned by Brian Ripley, is Debian's versions of the lapack and blas libraries. When Debian is used on a scientific/engineering workstation, those libraries are surely essential, even though the vast majority of users don't use them. They could, however, crop up anywhere, embedded in image processing routines, games etc.

A more actual example is provided by this thread: Use of aufs-tools to make no-wear Knoppix versions for flash memory. With widespread use, those tools could migrate into the "essential" category, I think.
