Does anybody know why loopback mounts stopped working when I went from 2.6.22
to 2.6.23-rc3? My config didn't change, the only thing that did was which
source tarball I pointed the build at.
If nobody else has hit this, I'll get around to debugging it eventually...

Does UML have any hotpluggable hardware? Somebody just contributed hotplug
support to mdev (a mini-udev replacement in busybox) and I'd like to test it
before committing it, and simulating hotplug under UML seems a nice way, but
I'm not quite sure how to yank and insert hardware under this thin
le program I use to get around this.

A) devfs is evil. Just don't go there.
B) The naming scheme in /sys goes more like /dev/ubda (and then there are

The skas page is a bit out of date:
http://user-mode-linux.sourceforge.net/skas.html
It only covers skas3, and doesn't even mention skas0...
