Just this morning I was having issues with a wacky dual-boot install with NixOS and Windows sharing an EFI partition, and quite interestingly ChatGPT and I were able to troubleshoot the process and get it resolved in under half and hour. I was really impressed by the specific configurations it was giving me for my /etc/nixos/configuration.nix , so that is also another resource you may consider leaning on when you run into walls in other documentation sources.
Do we prefer Ansible over Terraform?
