thanks to unionfs. For instance, nix-env and nixos-rebuild work.
The tricky part was to build a Nix database (in the tmpfs/unionfs)
which is now necessary to prevent store paths on the CD from being
deleted right away because they otherwise wouldn't be valid.
* nixos-install: use the /etc/nixos/configuration.nix from the target
file system (don't copy it anymore). Since the user is supposed to
mount the target file system on /mnt anyway, we may as well require
that configuration.nix is placed in /mnt/etc/nixos. This also makes
upgrading / reinstalling much easier, since it will automatically
use the right configuration.nix.

configuration.nix. Right now it finds out the following:
- How many CPUs the machine has (for nix.maxJobs).
- Whether to load KVM support (either kvm-intel or kvm-amd).
- The modules necessary for the initrd by scanning the PCI and USB
busses. Only mass-storage and HID related modules are added.

get the background image to work, you may need
to set NIXOS_INSTALL_GRUB=1 when calling
nixos-rebuild to force Grub to be reinstalled
with splashimage support.

for building parts of the system. E.g.
$ nix-build /etc/nixos/nixos -A upstartJobs.xserver
to build the Upstart job for the X server, or
$ nix-build /etc/nixos/nixos -A kernel
to build the NixOS kernel.
* /etc/profile.sh: if ~/.nix-defexpr doesn't exist yet, create it as a
directory and add links to root's channels, /etc/nixos/nixos and
/etc/nixos/install-source.nix (as "nixpkgs_sys").
* boot.useKernel -> boot.kernel.

as regular files instead of symlinks to the store.
* Sudo configuration, enabled through security.sudo.enable (on by
default). The contents of the sudoers file is specified in
security.sudo.configFile. The default sudoers file allows members
of the new "wheel" group to run any command.

don't need to be subscribed to the Nixpkgs channel to get binary downloads.
This is possible because nix-pull is now pretty fast.

/boot/kernels. This is necessary if /nix is on a different file
system than /. (And it will allow us to support a separate /boot
partition too.)

sources in /etc/nixos with a Subversion checkout of those trees.
This should be run after a successful installation if you want to
keep NixOS up to date from Subversion.

assumed to be in /etc/nixos/nixos and the system configuration in
/etc/nixos/configuration.nix. This is overridable through a few
environment variables.
* Installer: check that the mount point does in fact have a file
system mounted on it (so that we don't install in an empty /mnt),
and don't unmount afterwards for symmetry.

* Installer: continue if the MANIFEST on the CD is missing (useful if
we're not actually installing from a CD).
