Yes, _I_ can create many FSes. Not users. If user want to mark this
part of this site as non-important (for example, because it is cache
of it image gallery which stores thumbnails, which could take lot of
space but re-creatable on demand), I will need to create yet another
FS on his request. It is not a option.

I'll take a look. If it could skip some directories, marked with
special file (like gtar could), it could be a solution.
