My main need for this is obviously PA. PA's lifecycle is mostly bound
to "at least one session of the user who invoked us to be
around" (which is why we currently watch CK's database asynchronously
and kill ourselves when the last user session of the user who invoked
us is terminated.)
That said, as I wrote in another mail I am thinking of other hardware
managing daemons too. And those which provide network services, as
well as those providing user fs mounting services and finally database
interfaces such as dconf, e-d-s, ...
