* Remove the use of the NIXPKGS and NIXOS environment variables. Instead use $NIX_PATH. NIXOS_CONFIG is still supported. svn path=/nixos/trunk/; revision=32739 2012-03-02 12:38:22 +00:00			`{`

* Support a `system' argument for if you want to do hacky things like change a NixOS installation from x86_64-linux to i686-linux (or vice versa if you have distributed builds enabled - I used this upgrade from 32-bit to 64-bit NixOS). svn path=/nixos/trunk/; revision=18177 2009-11-06 01:00:44 +00:00			`system ? builtins.currentSystem,`

* Add a top-level default.nix for NixOS which has attributes useful for building parts of the system. E.g. $ nix-build /etc/nixos/nixos -A upstartJobs.xserver to build the Upstart job for the X server, or $ nix-build /etc/nixos/nixos -A kernel to build the NixOS kernel. * /etc/profile.sh: if ~/.nix-defexpr doesn't exist yet, create it as a directory and add links to root's channels, /etc/nixos/nixos and /etc/nixos/install-source.nix (as "nixpkgs_sys"). * boot.useKernel -> boot.kernel. svn path=/nixos/trunk/; revision=9334 2007-09-18 15:06:24 +00:00
