The namespace here is, unfortunately, pretty limited. The manpages
for mkreiserfs and mke2fs mention a 16-character limit for
filesystem labels, so you'd be out of luck trying to (for example)
represent /usr/local in the scheme above without truncating the
hostname to 5 characters. You can't fully represent a mount path
greater than 16 characters in a filesystem label even unprefixed.
Maybe a 14-byte hash of the hostname and path (or even just a
14-byte pseudo-random number, for that matter) represented in 7-bit
ASCII characters would achieve the desired goal? That'd look pretty
ugly though...
