Recently, I experimented with Debian sid, which installed systemd. Systemd idea is nice, but its implementation is a catastrophe. It is more than one year, maybe more than 2, I am using the kernel cgroups on gentoo to get rt scheduling with JACK, that without any trouble.
http://trac.jackaudio.org/wiki/Cgroups On that Debian system, this was just impossible, because whatever I try, systemd insisted to put what it think is good to have into the rt cgroup, which soon or later resulted in a complete system freeze with even dead magic keys. After loosing my time a few days with this, I removed Debian and installed gentoo instead. I just found the reason here: http://article.gmane.org/gmane.linux.kernel/1063354 "Lennart Poettering: Well, this feature is... completely irrelevant for normal desktop people. ... In fact, I just pom all otrepped a patch to systemd to move every service and every user session into its own cgroup in the 'cpu' hierarchy (in addition to the group it already creates in the 'systemd' hierarchy)." What terrify me in that story is the total lack of consideration for the needs of who the chief developer of systemd strongly suggest are abnormal desktop users. More, Lennart take one corner use case, compilation at the console, and generalize it to all other corner use cases, which is just impossible to do because a corner case is precisely a case that is different from all other cases, and all desktop users are potentially all a case by themselves. We are all different and each one of us make a different use of its desktop, so we are all, at different levels, corner case users. Last, this systemd patch is more than 3 years old now, and I also just found that freedesktop is involved in that mess: http://www.freedesktop.org/wiki/Software/systemd/ControlGroupInterface/ So, that imply, if I am right with my diagnostic, the next question is what can be done to solve that issue?
