Well, I thought of using the update daemon to do some periodic cleanups
in the caches of my nfs (coming soon to a computer near you).
The minix fs would have to be changed to do a sync only on those drives
it currently uses, i.e. move the checks from update to the fscntl()
function; then the floppy problem should be gone.

Even an automounter could then use it to flush its caches, so it would
not need to be a daemon.

BTW: is there a way to have a global timeout to call a certain function
like the normal timeouts in MiNT, but no associated with a certain process
which could be killed in the mean time?

Regards,
Ulrich
