nixpkgs/etc/profile.sh
Eelco Dolstra f2780fdc62 * 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.
