Thanks, though on reflection I don't think we need to do the
'stat's. Just checking the path names should be sufficient, but I will
double check.
non-explicit UUIDs are derived using libblkid, typically a UUID out of
the filesystem that is being exported.
The only problem is that it appears that libblkid isn't as efficient
as one might like and if you have hundreds of mounts, mountd can slow
down. I still need to look into that.
