From 17c0362178caf837680a4631b8d0de94e5393448 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.
