Great, I did just that, setup /usr with the installer -- basically stumbled upon a working solution, looks like things would have broken pre-F18...
Nice systemd-analyze results, incredible. What led me to your guide was NetworkManager's wait-online-service, which alone added 30 seconds to boot time! Down to 6 seconds now, and should get under 4 seconds with "sudo dracut -f -H -o plymouth" test that I'll run later today.
