20b364f4de Reverting revisions 30103-30106: "always set nixpkgs.config.{state,store}Dir", etc. 
After the change from revision 30103, nixos-rebuild suddenly consumed
freaky amounts of memory. I had to abort the process after it had
allocated well in excess of 30GB(!) of RAM. I'm not sure what is causing
this behavior, but undoing that assignment fixes the problem. The other
two commits needed to be revoked, too, because they depend on 30103.

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.

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
