Well this is what I have going on.  I'm basically building a poor man's
laptop with a usb zip250 drive.  I've got just enough to get booted up
but I need X and a java sdk which is too much to fit on 250 MB.  So what
I decided I would do is mount some shared memory on /dev/shm and install
the pacakages there.  When I get ready to shutdown, tar and bzip up the
files stored there to somewhere on disk.  Make any sense?

I downloaded the deb-src of xserver-common to mess around with.
