    "Rsync is a fast and versatile file copying tool.  It can copy locally,
to/from another host over any remote shell, or to/from a remote rsync daemon.
Its delta-transfer algorithm reduces the amount of data sent over the network
by sending only the differences between the source files and the existing
files in the destination.")

file, without requiring the old and new versions to both be present at the
sending end.  The library uses a \"streaming\" design similar to that of zlib
with the aim of allowing it to be embedded into many different applications.")

This
is quite fragile, very slow, and almost unusable without KVM.

For all these reasons, add support for host image generation. This implies the
use new image generation mechanisms.

- Raw disk images: images of partitions are created using tools such as mke2fs
  and mkdosfs depending on the partition file-system type. The partition
  images are then assembled into a final image using genimage.

- ISO9660 images: the ISO root directory is populated within the store. GNU
  xorriso is then called on that directory, in the exact same way as this is
  done in (gnu build vm) module.

Those mechanisms are built upon the new (gnu image) module.

* gnu/build/image: New file.
* gnu/local.mk: Add them.
