It was actually trivial: I started out with a single UML partition and
debugged that, then split the firewalling off into the separate UML
later when I was satisfied with it.

Plus UMLs are easy to hack at: if you bugger it up so badly the box
doesn't boot, just restart and try again :)

(I had *far* more problems with the bloody ADSL router; b.o.unix
passim.)
