Hi, i am actually not sure, WHY this is needed during package building time. Instead of going to upstream and ask them implementing it, or implementing it ourselves, i would question: 1. Why do we need this at all? There may be a hidden requirement of mozilla which i am not aware of, i will have a look. 2. Why is this a package-build-time-action and not a post-installation-action. We could move the call to the postinst (excuse my debian-speech here) and be done with that bug.
