Previously, the activation script was responsible for ensuring that /etc/machine-id exists. However, the only time it could not already exist is during stage-2-init, not while switching configurations, because one of the first things systemd does when starting up as PID 1 is to create this file. So I've moved the initialization to stage-2-init. Furthermore, since systemd will do the equivalent of systemd-machine-id-setup if /etc/machine-id doesn't have valid contents, we don't need to do that ourselves. We _do_, however, want to ensure that the file at least exists, because systemd also uses the non-existence of this file to guess that this is a first-boot situation. In that case, systemd tries to create some symlinks in /etc/systemd/system according to its presets, which it can't do because we've already populated /etc according to the current NixOS configuration. This is not necessary for any other activation script snippets, so it's okay to do it after stage-2-init runs the activation script. None of them declare a dependency on the "systemd" snippet. Also, most of them only create files or directories in ways that obviously don't need the machine-id set. |

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 https://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.
