I've been thinking for some time to try NixOS on some Pi's I have, as I need a few with very similar config. Bookmarking this for some Easter tinkering.
I guess it's obvious when you know NixOS, but for a n00b like me, perhaps point how exactly you used this. Like did you manually install it like the doc goes on about or did you create your own SD card, if so how?
Some links to existing stuff would be plenty fine.
