+Subject: [PATCH] Make initrd accessible only by root (#3123)
+
+Origin: https://github.com/rear/rear/commit/89b61793d80bc2cb2abe47a7d0549466fb087d16
+
+In pack/GNU/Linux/900_create_initramfs.sh call
+chmod 0600 "$TMP_DIR/$REAR_INITRD_FILENAME"
+to let only 'root' access the ReaR initrd because
+the ReaR recovery system in the initrd can contain secrets
+(not by default but when certain things are explicitly
+configured by the user like SSH keys without passphrase)
+see https://github.com/rear/rear/issues/3122
+and https://bugzilla.opensuse.org/show_bug.cgi?id=1218728
