Soft Updates
You will want to check out soft-updates if you have ffs, and most likely install it on all partitions except / (example for FreeBSD):
$ less -XF /usr/src/sys/contrib/softupdates/README
To see if you have soft-updates enabled: on FreeBSD:
$ mount /dev/ad0s1a on / (ufs, local) devfs on /dev (devfs, local) /dev/ad0s1g on /backup (ufs, local, soft-updates) /dev/ad0s1e on /tmp (ufs, local, soft-updates) /dev/ad0s1f on /usr (ufs, local, soft-updates) /dev/ad0s1d on /var (ufs, local, soft-updates)
on OpenBSD
$ mount /dev/wd0a on / type ffs (local, softdep) /dev/wd0e on /usr type ffs (NFS exported, local, nodev, softdep) /dev/wd0d on /var type ffs (local, nodev, nosuid, softdep) mfs:22707 on /tmp type mfs (asynchronous, local, nodev, nosuid, size=261120 512-blocks)
