No, I would strongly recommend against attempting to do this with dpkg-divert. The results will be very unpleasant and the number of semi-broken corner cases will be enormous. > But since dpkg-divert cannot divert directories, I?d either have to > collect the full list of broken files from the Contents files and > hard-code them, or do it via a trigger, which also seems to be overkill > for a work-around. I don't think you need a trigger for this. The code you write should be fast and can run in the single core package postinst. > I guess I?ll give the postinst-symlink-approach a shot. Do come back when you have more final-looking code and I'll see if I can find bugs in it :-). Ian. -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
