+==========
+iscsi-boot
+==========
+Handles configuration for the disk to be capable of serving as
+a remote root filesystem through iSCSI. Currently, this element
+only configures Ubuntu/Debian images.
+
+It performs the following actions:
+
+* Installs the ``open-iscsi`` package.
+* Creates the ``etc/iscsi/iscsi.initramfs`` configuration file and sets
+  ``ISCSI_AUTO=true`` within it.
+* Updates the initramfs to apply the changes.
