[systemd-devel] Non-target, dependency-only unit

[Pablo Nehab Hess]

I'm trying to convert Spacewalk's init script to a systemd unit file.

Spacewalk is merely a collection of dependencies; it depends on
{httpd,tomcat6,postgresql}.service and a few others, but there's no
proper daemon or any such thing. The original init script lives at
'/usr/sbin/spacewalk-service' and simply performs 'start' or 'stop' or
'restart'/'reload' for all those dependencies in a specific order.

If the only desirable action was 'start', then a target unit would be just fine.

However, the administrator must be able to at the very least 'stop'
and 'reload'/'restart' it.

The solution I've been using is inserting all but the last dependency
into 'ExecStartPre' and 'ExecStopPost' directives, but does *not* look
correct to me.

Is there any other solution I'm unaware of?

Thanks for any hints.
