Since the variable SYSTEMD_DIR= is expanded, $(prefix)/something would expand to /something because prefix= does not exist anymore once this whole series is applied. But as stated in an earier reply, maybe we expand to lowercase variables in Paths.mk and assign to our uppercase variables as needed. Then this patch can be dropped. Olaf
