I'm very much starting my journey here :) b) is the most elegant solution IMHO, it will always point to the right directory, at runtime. That makes as well upstream config relocatable, which is a net benefit for everyone :) Cheers, Didier -- Snapcraft mailing list Snapcraft@lists.snapcraft.io Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/snapcraft
