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.

Just set nix.distributedBuilds to true and nix.buildMachines
to a list of machines that can perform Nix builds via SSH,
and local builds will be forwarded appropriately. So now
any user can say something like
nix-build /etc/nixos/nixpkgs/ --arg system '"powerpc-linux"' -A libxml2
and the build for powerpc-linux will be forwarded to a machine
of that type.

* Don't use $fontconfig/var/cache/fontconfig as a cache (when running
as root), instead use /var/cache/fontconfig.

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.

CD-ROM drive, etc.) to the logged in user. Woohoo! Finally, no
more chown /dev/snd/*.
* Get rid of spurious error messages about pam_ldap when we're not
using LDAP.
