The OS now has associated /dev/ada0 to the device formerly known
as /dev/ad4, so the root partition needs to be adjusted in /etc/fstab
from /dev/ad4s1a to /dev/ada0s1a.
When in single-user mode, do this:
# mount -w /
so you can write to /, then use
# vi /etc/fstab
# ee /etc/fstab
to make the required changes (for the swap partition as well).
