Upstart is already not portable to non-Linux kernels. This is a known issue; had it not been for sensitivity to not breaking Debian's non-Linux ports, it's likely that upstart would have been the default in Debian before systemd was a glimmer in Lennart's eye. Unlike systemd, upstart is open to being ported to non-Linux kernels. Sadly, so far no one has stepped up to do this work. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
