I would suggest that you first use bsdlabel to create a single partition
on that slice. You can use the a: partition, or if you feel squimish
about using that one that is traditionally used for root, then use
the d: partition. Do this:
bsdlabel -w ad0s3 To initialize a partition label, then
bsdlabel -e ad0s3
You enter an edit more. Just duplicate the c: line
--Do NOT change the c: line--
edit that duplicate line and make it a: or d: or whatever.
Change the tuype to BSD4.2
You can add values for [fsize bsize bps/cpg], maybe to:
2048 16384 28552
But I think you can just leave them blank.
write/quit the edit session and the label is written.
Then you need to run newfs on that new partition.
newfs /dev/ad0s3a or newfs /dev/ad0s3d if you named it d:
Then, just edit /etc/fstab to make it mount at boot time
and mount it up. If you already have stuff in /home, then you will
need to make one of them a temporary mount somewhere to move stuff over.
