NixOS Facter aims to be an alternative to projects such as NixOS Hardware and nixos-generate-config. It solves the problem of bootstrapping NixOS configurations by deferring decisions about hardware and other aspects of the target platform to NixOS modules.
I read the spec, It seems useful if you want to do some server level tweaking like turning on the flags to make use of ECC RAM if there’s ECC RAM. But yeah the hardware can fix pretty damn solid two solid for me to even realize that someone made a project for better hardware control.
