I read this question, but I'm more confused yet.
- In developer.ubuntu.com/showdown I read: "(2) run out of /opt" (I understand "run out" is not in /opt *Am I wrong?*)
- In https://wiki.ubuntu.com/AppReviewBoard/Review/Guidelines#Packaging I read: "our package should install most files in /opt/extras.ubuntu.com/"
It's not clear for me if the app must be in the /opt or out /opt :$
Then, can I use the /usr? Will be the app rejected if it's on /usr?
