I was poking around Starfish, and along the way I noticed a broken symlink in the system:
$ file /etc/rpm/macros.systemd
/etc/rpm/macros.systemd: broken symbolic link to /usr/lib64/rpm/macros.d/macros.systemd
I don’t know how this affects matters in general, because rpm seems to be able to still find its contents:
$ rpm -E %_userunitdir
/usr/lib/systemd/user
