A channel to add specific custom packages without modifying the upstream nixpkgs, and allowing when to update nixpkgs.

• Clone this repository

  git clone https://github.com/Gricad/nix-ciment-channel.git

• Clone the nixpkgs repository at the release we are currently using

  git clone https://github.com/Gricad/nixpkgs.git
  cd nixpkgs
  git checkout release-17.09
  cd ..
  

• Link the nixpkgs directory

  cd nix-ciment-channel
  ln -s ../nixpkgs
  

• You can test to build a package

  # Build
  nix-build . -A ciment.hello
  # Install
  nix-env -i ./result
  

• Create the channel (OPTIONAL, if you are an admin)

  • Push your package into the binary-cache

    nix-push --dest /scratch/nix.cache $(nix-build -A ciment.hello)
    

  • Create the channel tarball

    tar cjf /var/www/nix/nixexprs.tar.bz2 nix-ciment-channel/ --exclude-vcs --dereference --exclude result
    

Custom packages can be push into the ciment directory. Upstream nixpkgs repository can be upgraded by a simple git pull from the nixpkgs directory. Then, if you're an admin , you can re-create the nixexprs.tar.bz2 file, after pushing new packages into the cache if needed.

• List ciment packages

  nix-env -qa -A ciment-channel.ciment

• Install a package

  nix-env -i -A ciment-channel.ciment.hello

• Every other official package may be installed as usual

  nix-env -i hello
