Ah, yes, I see. So maybe we should instead have:

ENABLED="no" 

in /etc/default/inadyn

and in the SXXinadyn, if ENABLED=="no", do something like:

Starting inadyn: SKIPPED

or something like that.

Thoughts?

Ah, you're talking about inadyn -b option, while I was thinking of the
start-stop-daemon option. Then it definitely makes sense, and I can get
rid of the background option in the example config file.

Sounds OK?

Thanks!
