be set from the NixOS configuration. For instance, you can say
nixpkgs.config.firefox.enableGeckoMediaPlayer = true;
environment.systemPackages = [ pkgs.firefox ];
but the more interesting application is to apply global overrides to
Nixpkgs throughout NixOS, e.g.
nixpkgs.config.packageOverrides = pkgs:
{ glibc = pkgs.glibc27;
gcc = pkgs.gcc42;
};
would build the whole system with Glibc 2.7 and GCC 4.2. (There are
some issues with "useFromStdenv" in all-packages.nix that need to be
fixed for packages in the stdenv bootstrap though.)
The implementation of this option is kind of evil though due to the
need to prevent a circularity between the evaluation of
nixpkgs.config and the "pkgs" module argument.

separate module, which just declares a configuration value that
causes the xinetd module to add it to xinetd.conf. Also Nixified
the service declarations to abstract over the inetd implementation.
* Renamed the services.xinetd.tftpd options to services.tftpd. The
fact that the tftpd module uses xinetd is an implementation detail.
* xinetd: use -dontfork to let Upstart monitor it, and use -syslog to
get error messages at startup.

* Let ConsoleKit track the current logins instead of pam_console.
Udev now takes care of setting the device permissions to the active
user. This works much better, since pam_console wouldn't apply
permissions to new (hot-plugged) devices. Also, the udev+ConsoleKit
approach supports user switching. (We don't have that for X yet,
but it already works for logins on virtual consoles: if you switch
between different users on differents VCs with Alt+Fn, the device
ownership will be changed automatically.)

the bus daemon can start on demand). ConsoleKit and PolicyKit need
this. This requires a setuid wrapper for dbus-daemon-launch-helper,
as well as a "messagebus" group.

programs require that the mode is 4550 so that execution of the
setuid program can be restricted to members of a group.
* setuid-wrappers: remove a race condition in the creation of the
wrappers if the ownership or mode was different than root:root and
4555.
* setuid-wrappers: allow the full path of the wrapped program to be
specified, rather than looking it up in $PATH.

For instance, the SLiM module simply declares:

sndMode option (udev puts all audio devices in the "audio" group, so
users can be added to that group if necessary).

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.
