size of the i686-linux ISO image from 463 MiB to 147 MiB. Hopefully
it also speeds up installation due to reduced seek time and larger
block sizes, but I haven't tested that yet (on real hardware).

rescue-dvd.nix (not tested though), i.e. it has all its extra
packages and includes the build-time dependencies.

iso-image.nix contains the minimal stuff necessary to build a
bootable ISO image containing the given configuration. The idea is
that this can be customised by providing additional modules, e.g. to
add extra packages to the image.
The ISO image is exported in the configuration attribute
system.build.isoImage. So it can be built as follows:
$ nix-build lib/eval-config.nix \
--arg configuration 'import ./modules/installer/cd-dvd/iso-image.nix' \
-A config.system.build.isoImage
