My patch only implements "locking" in the sense that you can't get access to
command-line, or edit menuentries, but you can run all existing entries.

If you want to "lock" in the sense of locking a single entry, my intention
was that this could be done with scripting as well:

menuentry locked {
        if [ $menu_lock = 1 ] ; then
                echo fail
        else
                blah
        fi
}

Is that what you mean?
