Do you mean you think the systemd landscape may change in the future, making it possible to port systemd to other kernels; or do you mean that you "would like to see" a single supported init system, but are willing to sacrifice this desire for a greater good of keeping Debian portable to other kernels? Given systemd upstream's oft-stated opinion that other kernels are irrelevant and that systemd should make the best use of available Linux features, the first of these seems exceedingly unlikely to come to pass. Indeed, it seems to me that systemd and upstart have been subjected to a double standard in much of the discussion on this bug, where we are open to the possibility of someone porting systemd to kFreeBSD and/or Hurd (despite zero evidence of anyone even entertaining the idea of doing so), but short shrift is given to statements that upstart upstream are committed to addressing various feature gaps that the TC considers important. With infinite resources and infinite will to match systemd feature-for-feature on Hurd and FreeBSD, it would obviously be possible to deliver the same experience on all architectures using systemd. But we shouldn't kid ourselves by treating this as a *likely* outcome. Adopting systemd is in fact a very high barrier to consolidating around the same init system for all ports, unless we drop the non-Linux ports. Maybe that's an important factor for Debian, maybe it's not; but I don't want us to be fooled into believing the choice of init system doesn't have an impact on whether that consolidation will happen. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
