Assuming that you are running FreeBSD (which I can not make for sure
from your message), you can always boot single user and correct the
files you need to change.
1. Reboot the system and at the boot loader prompt, press ESC instead
of the usual RETURN when you're prompted for a key.
2. Type 'boot -s' without the quotes to boot single-user.
3. When the system loads it's kernel and boots, it will only load a
/bin/sh to let you do your work.
4. Run the usual /bin/sh initialization scripts of root, because the
single-user shell does not run them automagically (it's not a login
shell, it's not supposed to run them):
# export HOME=/root
# cd
# . .profile
5. Step 4 must have fixed your PATH and other important environment
vars, let's move on to the real work.
6. Mount all disks that the old fstab was SUPPOSED to mount, manually.
This might involve a few `cat /etc/fstab' commands, to let you see
the actual device names and mount points. Be sure to mount as
read-write at least your / and /usr filesystems.
Example:
( remount root filesystem as read-write )
# mount -o rw -u /dev/ad0s1a /
( mount /usr as read-write )
# mount -t ufs /dev/ad0s2a /usr
Now, you are ready to use vi(1) or any other editor you prefer to edit
/etc/fstab to your will.
