Why not search all 2000 block devices for var? doesn't realy hurt. And
then, when var is there, the other 1999 filesystems can use the cache.
If the file is in /etc and / is RO and you change two drives the
system will mount the wrong filesystem. fsck will check the wrong
filesystem.
Also don't forget that the order in which modules are loaded can
change drive names. Loading and removing modules possibly invalidates
the cache. It might be enough to remove the cache upon boot and rescan
all devices when a UUID is not found in the cache (and update if new
uuids are found).

Isn't mount a buildin shell command in sash?
