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.

* Simplified the udev rules generation: merged nixRules into
services.udev.extraRules, and handle services.udev.extraRules using
services.udev.packages.

With these modifications, a user can configure a tomcat instance with web applications and web services by writing a service, such as:
...
services = {
tomcat = {
enable = true;
webapps = [ mypkgs.HelloWorldWebApplication ];
axis2 = {
enable = true;
services = [ mypkgs.HelloService mypkgs.HelloWorldService ];
};
};

jobs, e.g. (from the nscd job)
{ name = "nscd";
description = "Name Service Cache Daemon";
startOn = "startup";
stopOn = "shutdown";
environment = { LD_LIBRARY_PATH = nssModulesPath; };
preStart =
''
mkdir -m 0755 -p /var/run/nscd

};
The Upstart job is generated from this. The main goal is to provide
some abstraction from the Upstart syntax. For instance, this should
make it easier to upgrade to newer versions of Upstart, to switch to
an entirely different process management system (e.g. initng or
launchd), or to test a job independantly from Upstart. (However the
startOn and stopOn attributes are tied to Upstart's event model.)
