Argh. I am trying to build a fresh chroot with all of the applications + xephyr and icewm. I ran out of space when trying to build it in my 1 GB image file, so I've sacrificed my bootable debian partition and I'm building it there. When it's done, I'll put it in the image file.

It gets really really ugly if you run out of space in the middle of a big apt-get install process.
