This introduces an option that allows us to turn off stateful generation of Diffie-Hellman parameters, which in some way is still "stateful" as the generated DH params file is non-deterministic. However what we can avoid with this is to have an increased surface for failures during system startup, because generation of the parameters is done during build-time. Aside from adding a NixOS VM test it also restructures the type of the security.dhparams.params option, so that it's a submodule. A new defaultBitSize option is also there to allow users to set a system-wide default. I added a release notes entry that described what has changed and also included a few notes for module developers using this module, as the first usage already popped up in NixOS/nixpkgs#39507. Thanks to @Ekleog and @abbradar for reviewing.
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.
