Eelco Dolstra 05ff7baf48 * /var/lib/nova/networks should be readable by the `nobody' user,
because dnsmasq runs as nobody and reads its host list from there.

Eelco Dolstra 796b48c367 * Run smbd in its own session / process group (setsid) because smbd
now kills its process group when it exits.  Without setsid, this
  ends up killing the parent (i.e., the builder).
* Use port 445 instead of 139 because the CIFS kernel module tries
  port 445 first.  If there is an actual Samba running on the host, it
  would end up connecting to that one instead of our own and fail.

Sander van der Burg 9c722e474d - Added nixos-build-vms command, which builds a virtual network from a network.nix expression (also used by nixos-deploy-network)
- Added a backdoor option to the interactive run-vms script. This allows me to intergrate the virtual network approach with Disnix
- Small documentation fixes

Some explanation:

The nixos-build-vms command line tool can be used to build a virtual network of a network.nix specification.
For example, a network configuration (network.nix) could look like this:

{
  test1 = 
    {pkgs, config, ...}:
 
    {
      services.openssh.enable = true;
      ...
    };

  test2 =
    {pkgs, config, ...}:
    
    {
      services.openssh.enable = true;
      services.xserver.enable = true;
    }

    ;
}

By typing the following instruction:

$ nixos-build-vms -n network.nix

a virtual network is built, which can be started by typing:

$ ./result/bin/run-vms

It is also possible to enable a backdoor. In this case *.socket files are stored in the current directory
which can be used by the end-user to invoke remote instruction on a VM in the network through a Unix
domain socket.

For example by building the network with the following instructions:

$ nixos-build-vms -n network.nix --use-backdoor

and launching the virtual network:

$ ./result/bin/run-vms

You can find two socket files in your current directory, namely: test1.socket and test2.socket.
These Unix domain sockets can be used to remotely administer the test1 and test2 machine
in the virtual network.

For example by running:

$ socat ./test1.socket stdio
ls /root

You can retrieve the contents of the /root directory of the virtual machine with identifier test1

Eelco Dolstra c4f910f550 * Substitute the path of the system derivation directly in the stage 2
init script.  This removes the need for the `systemConfig' boot
  parameter; `init=<stage-2-init>' is enough.  However, the GRUB menu
  builder still needs to add `systemConfig' to the kernel command line
  for compatibility with old configurations.

Eelco Dolstra f729f12e4e Some cleanups in the activation script:
* Moved some scriptlets to the appropriate modules.
* Put the scriptlet that sets the default path at the start, since it
  never makes sense not to have it there.  It no longer needs to be
  declared as a dependency.
* If a scriptlet has no dependencies, it can be denoted as a plain
  string (i.e., `noDepEntry' is not needed anymore).

Eelco Dolstra c1295661c4 * Added a command `nixos-rebuild build-vm-with-bootloader'. This is
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.
