Right. First of all, swap partitions aren't "mounted" as such. You
just have to tell the system to start swapping onto the partition:
# swapon /dev/ad1s1b
To make that happen automatically on reboots, add a line like so to
/etc/fstab:
/dev/ad1s1b none swap sw 0 0
In order to mount your /data partition, either you need to tell the
mount command all the parameters it needs:
# mount -t ufs -o rw /dev/ad1s1e /data
or you need to enter the equivalent data into /fstab so that mount can
look up what it needs to know there. There are some other fields in
fstab that 'mount -p' will give default values, but that you'll
probably want to set to something useful. Try something like this in fstab:
/dev/ad1s1e /data ufs rw 2 2
Oh, and do make sure you've created a filesystem on the partition before
you try and mount it..
# newfs /dev/ad1s1e
Cheers,
Matthew
