minimal.conf: blatantly steal the collective wisdom (and I admit it must have
been ton of work, thanks koen et. al.) people put in the angstrom distribution configuration and reorganize the sections a bit for more clarity. Most of this is really distribution-independent, so I'd welcome if angstrom would include one or the other of these sane-*.inc and maintain it there.
