From 6ed389da85a9259c688aac91c859c804e29c485b Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Tue, 6 Mar 2018 08:25:32 +0100 Subject: [PATCH] base-files: sysupgrade: do not rely on opkg to list changed conffiles Many packages use the opkg conffiles field to list configuration files that are to be retained on upgrades. Make this work on systems without opkg.
