Well I had already achieved that on the pre cds by moving the tarballs 
to /sources instead of /usr/src - however, that's a minor point.

I think I like this idea. I had to go read up a little on unionfs 
because it wasn't clear to me at first what it was you were talking 
about. But it seems really cool. IIUC, unionfs sits 'on top' of the root 
tree and filters your access to files. It keeps track of which files you 
have modified and which you haven't and substitutes the modified version 
of a file stored 'on top' of the original when you request any file. 
Therefore, the *entire* tree can be writable (up to the amount of RAM 
available, I assume).

Very cool...

Alexander, tell you what... If you could provide a real patch to the 
init.c and whatever else needs to change to make the scripts build this, 
I'll make a branch in svn and we can test this setup. Let me know what 
you can do with regards to that.
