Your best solution may be to use mtools (ports/emulators/mtools) rather
than mounting the filesystem.

The only way to do this is to have all the other filesystems mounted
read-only.  The "filesystem clean" flag is part of the superblock and
is cleared when a filesystem is mounted.  It will be set only if the
filesystem is cleanly unmounted.
