Currently, when setting up lxd in funtoo, the following hack is required to support containers that use systemd:

1. mkdir -p /sys/fs/cgroup/systemd# mount -t cgroup -o none,name=systemd systemd /sys/fs/cgroup/systemd
   While funtoo will never use systemd, it should support systemd in containers by default, without requiring this hack. We should look into a fix for openrc so the systemd cgroup is available and mounted at boot automatically.
