Previously, netdev units for network interfaces defined in the nixos configurations would bindTo the systemd device unit of the interface if not in a container. In situations where you switch to a new nixos configration with changes to network-setup.service (like nameservers) and have stacked interfaces like vlans on a bond, it would fail to propagate restarts to the netdevs correctly resulting with broken networking. The bond would be present but no vlan interfaces rendering the machine unreachable. My fear is that the udev events fail to propagate correctly while a systemd transaction that is also restarting the triggered netdev service is running. This commit changes this behaviour so netdev services bindTo other netdev services if present and otherwise fall back to the previous behaviour. We also noticed that stacked interfaces would sometimes seemingly be stopped in the wrong order. For instance in the above example, the bond interface would be deleted before the vlan interfaces resulting in the vlan interfaces not being present when their service is being stopped. This would cause the systemd transaction to fail and thus break networking. Their postStop hooks are now allowed to fail as we have reached the desired state.
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-16.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-16.09
For pull-requests, please rebase onto nixpkgs master.
NixOS linux distribution source code is located inside
nixos/ folder.
