* Modularised the xorg.conf generation. For instance, the Wacom and
Synaptics support has been moved into separate modules. The
contents of xorg.conf is defined by the option
services.xserver.config, and various other options for specific
sections (e.g. services.xserver.serverLayoutSection).
* displayManager.job.env: made this an attribute set.
* tcpEnable -> enableTCP for naming consistency.
* defaultDepth can be set to 0 to leave it undefined (needed for the
vmware driver).
* Removed some options that seem obsolete or are now the default
(e.g. RenderAccel, AllowGLXWithComposite).
* Removed services.xserver.package. This can now be done using
nixpkgs.config.packageOverrides.

- NFS mounts are created during startup time
- Played a bit with waiting times in order to capture a nice screenshot

- Added rpc.statd service, which prevents messages that tell you that you should use -o nolock
- Create /var/lib/nfs on initialization
- Create /etc/exports, so that exportfs can create /var/lib/nfs/etab. This prevents errors such as: mount.nfs: an incorrect mount option was specified

3 server and two clients. The clients connect to the server and do
nothing (except getting blown by the bots). After a few seconds we
verify that the clients indeed connected successfully, and make a
screenshot of the X displays of the clients.

substitute some values, just prepend them to the start of kdmrc.
KDM will merge multiple sections with the same name (even though it
complains a bit). Option definitions that occur first have
precedence.

adding an attribute "password" that defines the default password for
an account. The default (null, as opposed to the empty string)
means not to set a password.

lib/build-vms.nix contains a function `buildVirtualNetwork' that
takes a specification of a network of machines (as an attribute set
of NixOS machine configurations) and builds a script that starts
each configuration in a separate QEMU/KVM VM and connects them
together in a virtual network. This script can be run manually to
test the VMs interactively. There is also a function `runTests'
that starts and runs the virtual network in a derivation, and
then executes a test specification that tells the VMs to do certain
things (i.e., letting one VM send an HTTP request to a webserver on
another VM). The tests are written in Perl (for now).
tests/subversion.nix shows a simple example, namely a network of two
machines: a webserver that runs the Subversion subservice, and a
client. Apache, Subversion and a few other packages are built with
coverage analysis instrumentation. For instance,
$ nix-build tests/subversion.nix -A vms
$ ./result/bin/run-vms
starts two QEMU/KVM instances. When they have finished booting, the
webserver can be accessed from the host through
http://localhost:8081/.
It also has a small test suite:
$ nix-build tests/subversion.nix -A report
This runs the VMs in a derivation, runs the tests, and then produces
a distributed code coverage analysis report (i.e. it shows the
combined coverage on both machines).
The Perl test driver program is in lib/test-driver. It executes
commands on the guest machines by connecting to a root shell running
on port 514 (provided by modules/testing/test-instrumentation.nix).
The VMs are connected together in a virtual network using QEMU's
multicast feature. This isn't very secure. At the very least,
other processes on the same machine can listen to or send packets on
the virtual network. On the plus side, we don't need to be root to
set up a multicast virtual network, so we can do it from a
derivation. Maybe we can use VDE instead.

into one argument "modules".
* 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.
