don't worry, it can be fixed.

1. Reboot your computer and when the boot's countdown  starts
   press space bar.

2. type:
		boot -s

3. your computer will stop asking for a shell that will be used
   in single-user mode.  just press enter to accept  /bin/sh

4. type
		swapon -a
		mount -a

   of course, /usr will not be mounted because you made something
   wrong with your /etc/fstab.

5. perhaps the system will ask you to fsck your file systems.
   do it.  you can add your the option "-y".

		fsck /dev/ad0s1a
		fsck /dev/ad0s1e
		...
		fsck /dev/ad0s1g


5. type
		cat /etc/fstab

   to see where /usr is mounted... [hope it is there].
   and mount /usr manually:

		mount /dev/ad0s1e /usr

   [ok, perhaps it is not ad0s1e, choose the proper partition]

6. edit /etc/fstab with your favorite editor, fix it, and save it.

7. reboot

Hope it helps.
