- 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
