Subject: [Buildroot] [PATCH] package/systemd: add checklist of upgrade caveats
Date: Mon, 10 Jan 2022 14:16:24 +0100	[thread overview]
Message-ID: <20220110131624.3639727-1-arnout@mind.be> (raw)

Bumping the version of systemd is a little more complicated than the
usual package, and it's easy to forget some of the things that need to
be done - and this has happened several times in the past.

Add a checklist of things to worry about when updating systemd.

Note that there are many other complicated packages that also need a lot
of attention when upgrading. However, systemd is a really critical
package so it's more important that we get that one right than, say,
valgrind.

+# When updating systemd, take care of the following:
+# - Check if the requirements have changed (see README), in particular
+#   arch and headers
+# - If yes, propagate the dependencies to BR2_INIT_SYSTEMD
+# - If the required kernel options have changed, update the Config.in
+#   help text and the list of KCONFIG_ENABLE_OPT.
+# - Check if there are new meson_options. Make sure all options are set
+#   explicitly (usually to default value).
+# - If there are new services:
+#   - create new options for them (if they really are optional);
+#   - create a new _USER if necessary;
+#   - create new directionry (with _PERMISSIONS) if necessary.
