grsecurity module: disable EFI runtime services by default
Enabling EFI runtime services provides a venue for injecting code into
the kernel.

When grsecurity is enabled, we close this by default by disabling access
to EFI runtime services.  The upshot of this is that
/sys/firmware/efi/efivars will be unavailable by default (and attempts
to mount it will fail).

This is not strictly a grsecurity related option, it could be made into
a general option, but it seems to be of particular interest to
grsecurity users (for non-grsecurity users, there are other, more
immediate kernel injection attack dangers to contend with anyway).

Build Status Code Triagers Badge Issue Stats Issue Stats

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-16.03 for the latest release and nixos-unstable for the latest successful build of master:

% git remote update channels
% git rebase channels/nixos-16.03

For pull-requests, please rebase onto nixpkgs master.

NixOS linux distribution source code is located inside nixos/ folder.
