Always enable both tty and serial console, but set preferred console depending on cfg.graphical. Even in qemu graphical mode, you can switch to the serial console via Ctrl+Alt+3. With that being done, you also don't need to specify `systemd.services."serial-getty@ttyS0".enable = true;` either as described in https://nixos.wiki/wiki/Cheatsheet#Building_a_service_as_a_VM_.28for_testing.29, as systemd automatically spawns a getty on consoles passwd via cmdline. This also means, vms built by 'nixos-rebuild build-vm' can simply be run properly in nographic mode by appending `-nographic` to `result/bin/run-*-vm`, without the need to explicitly add platform-specific QEMU_KERNEL_PARAMS.
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-18.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-18.03
For pull-requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
