@volth If I disable access to the binary cache and add
nixpkgs.localSystem.platform = pkgs.lib.systems.platforms.pc64 // {
gcc.arch = "skylake";
gcc.tune = "skylake";
};
to my /etc/nixos/configuration.nix, will that cause every package to be rebuilt on my computer with these optimized settings? If not, how can this be achieved? Ideally, I want to make NixOS as Gentoo-like as possible and build every package on my system with “-O3 -march=native …”
I know this breaks reproducibility/purity but packages will only ever be on my system so I’m fine with that. Is this even possible?
