Re: add in SATA card -- ada0 "moves" to ad1, breaking the boot process ?

I was able to fix my boot problem by doing:

boot single user,
tunefs -L 60Gboot-SATA /dev/ada1s1a
reboot single user again,
mount -rw /
fix /etc/fstab to use the label,
reboot into multi-user

However, now, the swap partition has disappeared:

tunefs -p /dev/ada1s1b
tunefs: /dev/ada1s1b: No such file or directory

Of course, I can evidence it once existed:

ls /dev/ada1*
/dev/ada1       /dev/ada1s1     /dev/ada1s1a    /dev/ada1s1b

Where did it go, and is it possible to use it, or is it gone forever?
(I know I can create a swap file on ada1s1a, so it's not the end of the
world.)

Thanks,
Bill Dudley
