I've got OpenBSD 4.2 on a net4801 and am mounting /dev in RAM. I'd like
to reduce the amount of memory used even further. Currently only %4 is
used:
Filesystem Size Used Avail Capacity Mounted on
mfs:21800 853K 34.0K 777K 4% /dev
What should I be aware of in /etc/fstab to minimize the memory footprint
of /dev? Currently, I have:
swap /dev mfs rw,-P/dev.base,-i1,-s2300,-c264,-m5,nosuid 0 0
Random changes to mfs' parameters aren't getting me anywhere. There
should be a rational way of arriving at optimal settings for mfs:
-b block-size
-c fragments-per-cylinder-group
-f frag-size
-i bytes
-m free-space
-s size
Regards,
-Lars
