replace-partition
-----------------
A standalone element which consumes a base image which was created with
``diskimage-builder`` and rebuilds it without making any packaging changes. This
allows the image contents to be copied to a new block device layout. Use cases
for this element include:
* Rebuilding a whole-disk image with a different partition layout by setting
``DIB_BLOCK_DEVICE_CONFIG``
* Rebuilding a whole-disk image with the same partitions but with the sector
size increased to 4096 bytes
replace-partition-redhat
------------------------
A redhat family specific version of the ``replace-partition`` element.
