+Subject: [PATCH] Merge pull request #2469 from
+ rear/skip-kernel-builtin-modules-issue2414
+
+In 400_copy_modules.sh skip copying kernel modules that are builtin modules.
+The new behaviour is that when modules are listed in modules.builtin
+and are also shown by modinfo then those modules are now skipped.
+Before for such modules the modules file(s) would have been included
+in the recovery system.
+See https://github.com/rear/rear/issues/2414
