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."
