Oh, I realise that.  Just a small joke about my non-random choice of
UUID... :)

Good thought!  It's very possible since of course only a crippled
environment is available at install time.  I'll try to verify it
later.

Hmmm.  I've hacked my init scripts to do it in the meanwhile, but I
will pay closer attention to what happens next time I boot and report

and a quite a few reasons to stay in 2.6....
