+Subject: [PATCH] Fix permissions when splitting rootfs folders across
+ partitions.
+
+This patches ensures that the file database containing the file and
+folder usernames and permissions is always located relative to the
+source and not to the appended rootfs-dir.
+
+Prior to this patch, the database was not found when using
+-rootfs-dir in the WIC script, leading to erronous file
+permissions and ownership.
