Jerry--No, dump/restore is the thing to use.
Jerry--Was the second slice /dev/ad0s2 made bootable - when you laid down
Jerry--the partitions?

I used sysinstall to lay down the partitions, then did a minimal install, so it was bootable I would assume.

Jerry--The problem is probably that you copied it directly including /etc/fstab.
Jerry--So, /etc/fstab still points to /dev/ad0s1a at the root (/) partition
Jerry--and /dev/ad0s1b as swap, etc, etc Those need to be manually edited
Jerry--after the dump/restore to be /dev/ad0s2a, /dev/ad0s2b, etc respectively.

Now that I think about it, yeah. fstab still points to the former slice. Funny how the obvious eludes you ad 2am. 
I will try that, and Thanks Very Much.
Steve.
