Ok that makes sense except for NFS (where disk time and local time tend
to diverge horribly). Also you might want to use posix locks not flock if you
want locks to work across a network - although I cannot see a single reason
why you'd want to do that at the moment.

updfstab only got run at boot generally. Either way the time checking sounds
a good idea - it means it'll fail safe for users who forget to read the docs
