This makes it possible to build several NixOS systems that use different
nixpkgs in the same nix-build invocation. Today, you can't do that since
the <nixpkgs> path reference is hard-coded in lib/eval-config.nix.
The environment variable "NIXOS_EXTRA_MODULES" is now checked to
contain a path to a file similar to modules/module-list.nix.
This gives the ability to include nixos modules that are not in the
nixos source tree.
This can be useful for modules that are still experimental, or which
aren't useful for other nixos users. Of course, this was already
possible to do this using a forked nixos tree, but with this
functionality, you can just rely on the nixos channel, easing things a
lot.
like `build-vm', but boots using the regular boot loader (i.e. GRUB
1 or 2) rather than booting directly from the kernel/initrd. Thus
it allows testing of GRUB.

versa if you have distributed builds enabled - I used this upgrade

* release.nix: fixed the manual job.
* ISO generation: break an infinite recursion. Don't know why this
suddenly happens. Probably because of the nixpkgs.config change,
but I don't see why. Maybe the option evaluation is too strict.

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.

empty.

same functionality by overriding config.system.path (or defining
config.system.systemPackages with a higher priority - don't know if
that works though).

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)

* 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).
