Though I just made it last week, it does not work well. It sometimes
"freezes" within a very short time of the completion of it booting.
When shutting down, it sometimes seems to get the cpu into a tight loop

one of the two reasons I want rescue mode available and working, though
it too has its limitations. (Samuel correctly recognizes the other
reason in his second post to this thread.)
