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.. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
