Arch's and Gentoo's sysv init don't do it. In my experience - I have tested this on Gentoo and on Arch - these parallelizations make booting a lot slower particularly on older and slower systems. > Arch's init system is completely ignorant of dependencies. Is this really an issue? I mean, Gentoo's init system is aware of dependencies. But I really haven't missed this on Arch. I usually know by myself, that apache first needs a network being set up. And I have the impression that this makes Arch's init system slightly faster and more KISS like. > This does not happen.

And if apache is patched can this behaviour of systemd be turned off? Heiko
