In the past (is this still the case?) it could only handle a subset
of uid's and/or gid's (0-255 or 0-511 or so), which is a problem for
backups with user data (and high id's). We patched it to handle
that many *different* id's, so in fact inserting a lookup table at
mkcramfs time (and also interpreting it in the fs code, of course),
but it is still limited to that amount of id's.
