Add a manual way for someone to set TRIM if they really want it. touch /root/TRIM_set and reboot to set, touch /root/TRIM_unset to clear.
Have to reboot after setting the tunefs flag or when mount is run, it clears any changes. No way to do it on the fly.
Add a means to force a fsck (on rare occasions the fs is not marked dirty, but still needs fsck run to fix errors)
