An anonymous reader writes: One of the most intrusive and controversal changes in the recent past was the anouncement of systemd (aka: Poetterkits). The developers defend and enforce the adaption, leaving out BSD and other UNIX like operating systems. One of their main selling points was the easy administration and huge performance during Linux boot up.
Phoronix has covered an article with backed up values. They came to the conclusion that: "Due to the user-space slowdown, the overall boot time with Fedora 18 is slower than with Fedora 17 from the Intel x86_64 systems that were used for this preliminary Fedora 18 benchmarking."
I confirm the Phoronix article and even beyond that, systemd doesn't behave as expected. Often it's required to enable or disable a service multiple times to have it either stay enabled or disabled. Even having remaining bits in /etc/rc.x causes a lot of irritation and administration annoyances.
