This means that it is possible to use MPTCP with NixOS by adding `boot.kernelPackages = pkgs.linuxPackages_mptcp;` to your /etc/nixos/configuration.nix. NixOS[1] is a "Purely Functional Linux Distribution" with a completely declarative configuration. This makes it easy to build reproducible systems and share them. It also handles atomic updates and rollbacks. You may also be interested by the very concise declaration of the package [2]. The package is built by declaring only the sources, the kernel options and some metadata. This patch only provides the required packages, and does not handle the configuration of MPTCP. As is, the kernel is already usable for a server, as it will accept mptcp connections, but comes with the dummy path manager. As usual, you need to configure manually the source routing tables and pick the right path manager. It would be a great addition to NixOS to add declarative options to select the path manager, the interfaces that should participate in the mesh and to handle the source routing. This remains to be done... Regards, Guillaume. [1] http://nixos.org/ [2] https://github.com/NixOS/nixpkgs/blob/master/pkgs/os-specific/linux/kernel/linux-mptcp.nix
