After modifying the shell script to include the line you posted, my unit now takes about 20-25 seconds to boot. It sits there building the database... When it's done, empwake is not in the Hijack menu.
Looking through serial, it reports I have a database size mismatch error...
Do you have only a SINGLE drive system? Mounting /drive0 in the preinit with the above line, prevents the player from finding and mounting my second disk, causing the database error.
