Before this commit updating /var/setuid-wrappers/ folder introduced a small window where NixOS activation scripts could be terminated and resulted into empty /var/setuid-wrappers/ folder. That's very unfortunate because one might lose sudo binary. Instead we use two atomic operations mv and ln (as described in https://axialcorps.com/2013/07/03/atomically-replacing-files-and-directories/) to achieve atomicity. Since /var/setuid-wrappers is not a directory anymore, tmpfs mountpoints were removed in installation scripts and in boot process. Tested: - upgrade /var/setuid-wrappers/ from folder to a symlink - make sure /run/setuid-wrappers-dirs/ legacy symlink is really deleted
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.
