Wouldn't some ways of identifying filesystems (ext2/3 labels?) more
easily be done from userspace?  Would it be possible to do what you want
from userspace using the fsid export option?  There's no reason the
fsid= option has to be set manually; you could generate /etc/exports
lines (or exportfs commands) automatically.
