The service '${1}' from '${PKGNAME}-${VERSION}' won't be registered
into the runlevel '${2}', therefore it will remain disabled at boot.

To start it at boot time, use the following command:

	$ rc-update add ${1} ${2}

To disable it again use:

	$ rc-update del ${1} ${2}

To start the service:

	$ rc-service start ${1}
