Yea i know its ugly, but if we can get a usable loopfs running then we
have absolutely no space problems at all. But we will have to get around
a few problems if we are going to use a loopfs.

Well, if we need more than 4MB of space in /usr then it will mean that
we can only install to machines with more than 8MB, which effictively
means you need 16MB to install debian.

In my eyes this would be unacceptable, im all for useing ramfs to make
the most of machines that do have a lot of RAM but we have to have a
backup plan for those who dont.

If we can get a loopfs working we might even be able to install to
machines with 4MB
