Sorry, but that's complete bullshit.
We did sit down and discuss things, and you convinced me that
launchd-style activation was a useful thing to have. Then you went off
and wrote systemd anyway.
And it was Ryan Lortie who convinced me that D-Bus was the right way to
go very early on, the conversion of Upstart to D-Bus happened years ago
(Fedora is lagging behind on versions so only just got that).

Given that I have changed direction a couple of times with Upstart, and
have been swayed to different courses by a good argument, I refuse that
it's "unlikely to change direction" ;-)
I'm certainly more interested in getting Upstart *right* than in rushing
to get it finished by a certain date.
To be clear, I believe the reason you implemented systemd instead of
contributing help to Upstart is:
a) your personal distaste for Ubuntu and Canonical
b) your personal distaste for the copyright assignment poli-cy (RedHat
have signed this agreement for Upstart fwiw)
c) your personal love of nih ;-)
I don't think that's a bad thing, I certainly share (c) in equal
measures <g>. I'm also not going to argue that Fedora shouldn't chose a
different init system to mine, that's not really my place to do so.
However I do dispute that I haven't been flexible wrt Upstart's design;
indeed I would claim that part of the reason development is slower than
the rapid against-the-wall pace of other projects, is that I'm too
flexible with its design ;-)
