	+
	Supported service-handling `_commands_` are `start`, `stop`, `enable`

	configuration file `__file__`. Multiple commands must be comma (`,`)
	or semicolon (`;`) separated. If the directives conflict, the last
	one is used.
	+
	The service plugin supports configuration overlays only for systemd.
	In other init systems, this directive is ignored. The configuration
	overlay files are copied to `/etc/systemd/system/__service_name__.service.d/`
	directories. Upon profile unloading, the directory is removed if it is empty.
	+
	With systemd, the `start` command is implemented by `restart` in order
	to allow loading of the service configuration file overlay.

	NOTE: With non-systemd init systems, the plug-in operates on the
	current runlevel only.
