Hello everyone.
Decided to give NixOS a try. Found a couple different places explaining how to go about installing without broadcom’s wireless driver in place. Including creating a new iso image with the broadcom_sta kernel module, unfree enabled etc. Problem is, after i run the “nix-build ‘<nixpkgs/nixos>’ -A config.system.build.isoImage -I nixos-config=iso.nix” the system tried grabbing tar packages from mirror.easyname.at/acl.tar.gz which obviously isn’t going well without the wireless drivers in place. The system isn’t resolving host names. Seeing as it can’t talk to the router, I guess that makes sense. Then I get dependencies of derivation /nix/store/longnumberlibarchive.drv system-path.drv x86-64-linux.iso.drv failed to build.
Is there a limitation on the live image that it can’t build a new iso image? Or is there a better way in getting the broadcom wireless drivers to load? Any help would be appreciated. I’m about ready to just install Mint with the nix package manager if I can’t figure it out
