I had asked Nous and Artoo whether it was worth placing those packages back in the AUR, and they said it wasn't, so I gave up. But maybe systemd-free.org can be referred instead of the AUR. About "the right way", I'm not sure it's true, for example, the Wiki lists at least 3 ways to use an nvidia graphic card. Nonetheless, what you said does sound like a good idea. Thank you. João Miguel
