From af357d6ab00d8ca258dfd7abb689d6fd2eb4090f Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Thu, 14 Jul 2011 15:32:03 -0500 Subject: Allow fileconflict if unowned file moving into backup array The bulk of this commit is adding new tests to ensure the new behavior works without disrupting old behavior. This is a relatively sane maneuver when a package adds a conf file (e.g. '/etc/mercurial/hgrc') that was not previously in the package, but it is placed in the backup array. In essence, we can treat the existing file as having always been a part of the package and do our normal compare/install as pacnew logic checks.
