Well done! It seems like you have learned a lot in that short period of time. My NixOS birthday was on January 29th, one week ago. Flakes and Overlays feels Greek to me. Have been stuck for a while now due to this NVIDIA issue. Had never heard about Disko before you mentioned it. Sounds smart as well. Ideally, I will manage to use NixOS to easily set up three different computers, so “script installers” (if that is an expression) is something I have to look into as well.
Well, I guess I should not clutter up this thread. I see a Discourse message telling me to consider writing DMs instead.
Anyhow, my system is still building. Hopefully, it will work when it is done. As well, maybe the PR / code change will be deployed soon. Then, I guess another build is needed.
