Thanks, that definitely looks interesting; reading it I actually would
love to see this implemented to ease the user from switching from one
to another init system, or whatever needs switching in the future.

Let me stop you right here; part of this idea came to mind yesterday,
but I saw a flaw in it so I did not suggest it:

  What if a certain profile needs to support two such profiles (eg.
  upstart and systemd) that have conflicting choices (eg. one profile
  lists -systemd, the other systemd); then you can no longer list both
  as a parent as they will simply clash and make conflicting changes.

Of course this isn't a problem for this situation, but it may become a
problem in a future situation if we're going to follow this practice;
that's why I think now that mix-in profiles fit the purpose better.
