Currently, we have a 'jack' package with attrname 'jack1d' and a
'jackdbus' package with attrname 'jackaudio'. Make it consistent 'jack1'
and 'jack2' in both package name and attrname.
This aligns the naming with what can be found on the JACK homepage.
Q: what's the difference between jack1 and jack2?
