We (including lennart) have been discussing about the benefits to do
it in post-systemd, this will not be run as a regular init, but post
manager_loop(). Being pid1 we can use kill(-1), wait() will work for
every process, etc.

if we need things like UPS, better to make that uniform and always
call it if present.
