No. There are no problems with mtab as a real file if it is handled
correctly, and handling it correctly is trivial. Simply:

1) Run "mount -n /proc" before running fsck.
2) Remount / rw as usual.
3) Immediately after remounting /, clear mtab and initialize it with
   "mount -f" for each mounted filesystem (/, /proc, and /dev if devfs
   is enabled).
4) Mount remaining filesystems as usual.
