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.
