I’m curious about how I’ve written the config rather than what stuff I’ve actually installed. Would you recommend writing any parts differently?
I saw that. Looks interesting and I’d like to check it out after I get the hang of vanilla stuff first, before it “fails catastrophically” (as it says in the README) on me without me knowing what happened.
For now, I have a setup.sh script that builds my home folder and dotfiles on Windows, Linux flavors (the normal FHS type), and macOS. So for now I’d like to learn about Nix by using it at the system level, and not worry about managing my home folder with just yet.
Haha, funny. (That’s a joke right?). I’m in Oakland. 
Ah, I knew someone would say this. Mind showing an example?
Ah thanks, I missed that part. That explains why it asked me to enter my sudo password when trying to connect to WiFi.
Ah, nice to know. See, as a brand new first-time NixOS user, I simply had no idea. It isn’t obvious for a total beginner.
What I had done was take the default config generated by nixos-generate-config, which already had those DHCP lines, then I simply added the networkmanager line, but I didn’t know that network manager would do that.
So basically, if I add networkmanager, should I just remove all the DHCP-related lines?
I haven’t tried it yet. The thing is, if my system and all the programs I need work great on X11, why should I switch to Wayland? If you don’t mind going into more detail on this, I opened another thread specifically about this at Newb question: Any caveats with Gnome + Wayland? Is it worth moving to Wayland instead of X11?
EDIT: You already replied there. Thanks.
