Having fixed the Google Compute Engine image build process's copying of store paths in PR #24264, I ran `nixos-rebuild --upgrade switch`... and the GCE image broke again, because it sets the NixOS configuration option for the sysctl variable `kernel.yama.ptrace_scope` to `mkDefault "1"`, i.e., with override priority 1000, and now the `sysctl` module sets the same option to `mkDefault "0"` (this was changed in commit 86721a5f78718caf10c578e9501f8b4d19c0eb44). This patch raises the override priority of the Google Compute Engine image configuration's definition of the Yama sysctl option to 500 (still lower than the priority of an unmodified option definition). I have tested that this patch allows the Google Compute Engine image to again build successfully for me.
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.
