Hi Garrett,
Marcel, seems to think that just by allowing the implementation of
alternatives to D-Bus in Upstart would cause bloating in Upstart. I find
that argument without merit. There is a bunch of functions in

Hi,

Actually, this is the only supported way.
In most circumstances (i.e. on anything but limited embedded systems)
this makes sense.

Well, at minimum you'd need _some_ method to tell Upstart that the dbus

Hm, I'd actually prefer somehow, if core tools, like

Any particular reason?

If the process dies, Upstart will receive SIGCHLD, and if marked

Detecting things like a stoned process is more interesting.

Hi Sarvi,
Its high time we stepped up a layer from plain Unix domain sockets and
talked a higher level API. And I agree D-Bus is very likely the
equivalent 'Unix Domain Sockets' for this purpose. But unfortunatley its
not there yet. All this means is that D-Bus needs some more time to
mature
Hi Sarvi,
But that said, D-Bus is a fine choice for now. I hope though, the
Upstart community is open to code contributions from us that
allow for
modular alternatives to D-Bus. Ofcourse without compromising on
performance or clean code.
I think that Scott and I explained that
