My /etc/fstab on the system that started out using 2.2.8 looks like # Device Mountpoint FStype Options Dump Pass# /dev/ad0s1b none swap sw 0 0 /dev/ad0s1a / ufs rw 1 1 /dev/ad3s1f /tmp ufs rw 2 2 /dev/ad0s1e /usr ufs rw 2 2 /dev/ad3s1e /var ufs rw 2 2 Just make sure you have those devices. There is an example of creating the devices in /usr/src/UPDATING around line 216. Kent > > Meanwhile, my kernel is slightly out of synch with my userland, but so far > it seems to be working.
