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.

into a NixOS module (modules/system/activation/top-level.nix -
couldn't think of a better name). The top-level derivation is
returned in config.system.build.system.
* Inlined system.sh in top-level.nix so that we don't have to pass
everything through environment variables.

modules/config/system-path.nix. system/system.nix is now almost
empty.
* Removed the cleanStart option - it should be possible to get the
same functionality by overriding config.system.path (or defining
config.system.systemPackages with a higher priority - don't know if
that works though).

/bin/sh will fail when using the new chroot implementation, which
only bind-mounts the inputs of a build rather than the whole Nix

- Remove Arguments that can be accessed either by "config" or "pkgs".
- Use the new scheme for upstart-jobs/default.nix.
This is now a configuration file which is imported by system/options.nix.
- Jobs can now include upstart-job/default.nix:
* upstrat-jobs/cron.nix
* upstart-jobs/dhclient.nix
=> No Nixos file refers to upstart-jobs/default.nix except if one of its options is require to define an extra job. (e.g.: cron, dhclient)

* Add nix-hardware-scan to the system.
* Upstart: don't use the -v flag.
* Include the NixOS version in the ISO image filename.
* Include testdisk and ms-sys in the CD.

the Intel 2200 firmware.)
* Firmware loader: don't write in /tmp. Also a hack to quickly
test new firmwares.
* Revert r10105 since the build fails if configuration.nix
is a symlink. Anyway copying configuration.nix does not
necessarily make sense since it can import other expressions,
which would also have to be copied. Perhaps a better
approach would be to write a serialisation of the config
to a file (maybe with builtins.toXML).

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.
