<pre>At early boot systemd will mount all controller hierarchies enabled in the
kernel into /sys/fs/cgroup/ into individual subdirs. Afterwards it will mount
/sys/fs/cgroup/ (but not the hierarchies below) read-only.
This means that if you have the "freezer" cgroup hierarchy enabled in the
kernel it will find it mounted there anyway. If you do not have it enabled in
the kernel you can't mount it anyway. Hence mounting the fs there read-only is
the right thing to do.</pre>
