-XXX TODO: on the goodies of --image-type, qcow2-hurd
+The new implementation of the `disk-image` command was followed by the
+introduction of an `--image-type` or `-t` option.  This option allows to
+produce disk images targeting different supports. The `hurd-raw` and
+`hurd-qcow2` image types, producing respectively a raw Hurd disk-image and a
+Hurd QCOW2 disk-image were introduced. They can be used this way:
+
+```
+guix system disk-image -t hurd-raw bare-hurd.tmpl
+guix system disk-image -t hurd-qcow2 bare-hurd.tmpl
+```

+This mechanism providing much more flexibility in the Guix System image
+generation will be described in a future blog post.
