Simply boot single user mode, update /etc/fstab and reboot.. if you
really care, then you should be using labeled providers, and then it'll
just magicly work... assuming you use the label provider in your
/etc/fstab..
I don't think we should EVER magicly mount root if /etc/fstab disagrees..
Unix is suppose to do what you tell it to... If /dev/ad4 doesn't exist
anymore, then it shouldn't boot until you fix it..
