could you double check your screencast ? My understanding is limited, but I think Systemd ver 205 changes the cgroup interaction methodology - basically systemd is a single point entry into the cgroup api. You cannot touch cgroup any other way except through systemd. FYI - this is not systemd taking arbitrary control but what the upstream kernel recommended.
My understanding is that Fedora 20 (which uses systemd 208 ) will be impacted by this, as will most other distros. However jessie is proposing systemd 204, so your method might still work.
Is there a reason for this? I'm heavily invested in Ubuntu and I'm also making heavy use of the cgroups API in its current form. Does that mean that I can't use cgroups without systemd in newer kernels? Or do I miss cgroups features?
I'm quite happy with the mountable filesystem at the moment. It's scriptable and reasonable flexible and still easy to use for solving my problems.
That sounds awful. The idea that systemd vs. another "cgroups owner" changes the API you need to use for interacting with cgroups will effectively impose a compatibility burden for every app that wants to take advantage of it.
Also, it is all command line at this point, but there are some concepts floating around about creating a gui @ http://mairin.wordpress.com/2011/05/13/ideas-for-a-cgroups-u...
