So "the platform" is whatever Lennart/Fedora want it to be? Upstart was there first, as one of the commenters says. Neither upstart nor systemd is part of "traditional" Linux. And there are those who say the "platform" should be Unix-like systems, not Linux and certainly not Fedora specifically. Having abandoned the BSDs and others (Lennart is quite open about not caring about them), the next step is to abandon Ubuntu, Gentoo and others. Fine, but don't pretend that you are supporting some sort of "standard platform" and they are not.
