A module for security options that are too small to warrant their own module. The impetus for adding this module is to make it more convenient to override the behavior of the hardened profile wrt user namespaces. Without a dedicated option for user namespaces, the user needs to 1) know which sysctl knob controls userns 2) know how large a value the sysctl knob needs to allow e.g., Nix sandbox builds to work In the future, other mitigations currently enabled by the hardened profile may be promoted to options in this module.
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-18.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-18.09
For pull-requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
