	DOC_CONTENTS="
	For openrc, there is an init script provided with the package.
	You _should_ only need to symlink /etc/init.d/lxc to
	/etc/init.d/lxc.configname to start the container defined in
	/etc/lxc/configname.conf.

	Correspondingly, for systemd a service file lxc@.service is installed.
	Enable and start lxc@configname in order to start the container defined
	in /etc/lxc/configname.conf.

	If you want checkpoint/restore functionality, please install criu
	(sys-process/criu)."
