Please note that mountall is only involved in the mounting at boot, it has nothing to do with shutdown. The messages shown here come from a sysvinit script.
The spurious messages on shutdown about unmounting not-mounted filesystems have previously been reported as bug #1097321.
The error reporting that the root filesystem is busy is a more serious issue that can have various causes. We should figure out what's holding the root filesystem open on your system and fix it.
