-- installed systemd and udev packages should have the same version.
-
-  These days udev and systemd are so related that it doesn't semm correct to
-  allow running systemd with udev having a different version.
+- cleanup specfile by removing commands that were dealing with systemd
+  pre-generated files: we're now using systemd tarball generated directly
+  from the git repo which doesn't contain any of these files.
+- there's no point in using LUA in %pretrans
