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
