The only fix for a mangled root is to boot off your backup root partition, or
if no backup root partition exists, a different device.  The other device
can include floppy, tape, etc.

Once you  have booted the other root, you can use fsdb and/or fsck to fix
most of the problems.  If you have real bad problems (like /unix got trashed or
lots of directories got trashed and you don't want to spend 3 days going
through lost+found and trying to figure which file goes where) you can read
in the last root backup that you have.

You have to have some alternative method of booting the system, otherwise
how did you get the os on there in the first place.
