  Modified files:
    sbin/fsck_ffs        main.c 
  Log:
  For a mounted file system which is read-only, when
  doing the MNT_RELOAD, pass in "ro" and "update"
  string mount options to nmount() instead of MNT_RDONLY and MNT_UPDATE flags.
  
  Due to the complexity of the mount parsing code especially
  with respect to the root file system, passing in MNT_RDONLY and MNT_UPDATE
  flags would do weird things and would cause fsck to convert the root
  file system from a read-only mount to read-write.
  
  To test:
   - boot into single user mode
   - show mounted file systems with: mount
   - root file system should be mounted read-only
   - fsck /
   - show mounted file systems with: mount
   - root file system should still be mounted read-only
