What is the idea behind this? Now we end up with paths like: /sys/fs/cgroup/memory/machine.slice/machine-lxc\x2dmyfunnycontainer.scope
The string prefix 'machine' is a special systemd string. The second part is the libvirt name 'lxc-$containername'. Systemd requires that the '-' be escaped hence we use '\x2d' here. You'll see this in a number of other systemd unit names too.
Srsly? I really hoped that this is a libvirt bug and not something by (systemd-)design. :-\ Thanks, //richard
