No, it is just a copy of what is in /etc, explaining how this linux was 
put together, for people who want to read it without doing a large .gz 
download first.

Nor am I, I am in DOS.  It is set up the way BL3.32 was set up.

I tried to umount things.  I don't think I was in the chrooted terminal at 
the time.  But at one point I had 5 loop modules when I typed ps and could 
not insmod anything else loop.  I am pretty sure that I umounted at least 
once without chrooting and the loop remained.

I tried three different busybox umounts.
Maybe mount is getting confused by scsi.  Do you have usb-uhci.o that I 
can try in case it works better?
