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. > Take a look at e.g. archivers/star. I'll take a look. If it could skip some directories, marked with special file (like gtar could), it could be a solution. --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
