Hi Guido,
for all my replies, keep in mind, that I don't have any idea what
serverspec is or does...

I quickly checked "service" from a Fedora installation. It doesn't seem
to use --no-pager (see the attached files).
Does service really behave differently on other distros?

But you know which system does use systemd, so you could setup the
servespec config accordingly to use "is-active"?

Urgh...

See above. I'm not sure if other distros actually behave differently.
Would like to know more if you have any references.
