Yes, documenting the alternatives to the "default" is IMO an obvious
prerequisite to declaring it ready for prime time (thinking of the day
jessie will become stable).
Now I still wonder about the practicality of "aptitude install
sysvinit-core systemd-shim": due to the far-reaching dependencies and
exclusion rules, it seems that an already installed system (like an
already running one that underwent an upgrade) will not trivially
accept the move (that is, without asking to uninstall 90% of the
system). I would like to say "atomically remove systemd-sysv and
install sysvinit-core systemd-shim" but the way to do so escapes me.
What am I missing ?
