Eelco Dolstra 89ef5c979b * New nixos-rebuild action: "nixos-rebuild build-vm" builds a virtual
machine containing a replica (minus the state) of the system
  configuration.  This is mostly useful for testing configuration
  changes prior to doing an actual "nixos-rebuild switch" (or even
  "nixos-rebuild test").  The VM can be started as follows:

  $ nixos-rebuild build-vm
  $ ./result/bin/run-*-vm

  which starts a KVM/QEMU instance.  Additional QEMU options can be
  passed through the QEMU_OPTS environment variable
  (e.g. QEMU_OPTS="-redir tcp:8080::80" to forward a host port to the
  guest).  The fileSystem attribute of the regular system
  configuration is ignored (using mkOverride), because obviously we
  can't allow the VM to access the host's block devices.  Instead, at
  startup the VM creates an empty disk image in ./<hostname>.qcow2 to
  store the VM's root filesystem.

  Building a VM in this way is efficient because the VM shares its Nix
  store with the host (through a CIFS mount).  However, because the
  Nix store of the host is mounted read-only in the guest, you cannot
  run Nix build actions inside the VM.  Therefore the VM can only be
  reconfigured by re-running "nixos-rebuild build-vm" on the host and
  restarting the VM.

Eelco Dolstra b56d08fc83 * Move the hardware modules back to the main modules tree. No need
for a separate tree.
  
* Pass the path of the modules tree to modules so that you don't have
  to write absolute paths, e.g. you can say

    require = [ "${modulesPath}/hardware/network/intel-3945abg.nix" ];

  instead of

    require = [ /etc/nixos/nixos/hardware/network/intel-3945abg.nix ];

  The latter is bad because it makes it hard to build from a different
  NixOS source tree.

Eelco Dolstra e4e408293e * Modularise the building of the installation CD/DVD. The module
iso-image.nix contains the minimal stuff necessary to build a
  bootable ISO image containing the given configuration.  The idea is
  that this can be customised by providing additional modules, e.g. to
  add extra packages to the image.

  The ISO image is exported in the configuration attribute
  system.build.isoImage.  So it can be built as follows:

  $ nix-build lib/eval-config.nix \
      --arg configuration 'import ./modules/installer/cd-dvd/iso-image.nix' \
      -A config.system.build.isoImage
