distribution refers to the base image that the ramdisk will be built on,
release is used to specify the distribution variant.
element is a concept of diskimage-builder, each element is handling part of
the building process,
you can take a look at the diskimage-builder documentation for a complete
list [1].
In case further customization on the ramdisk is required, elements can be
included by the argument.
We have some examples on how to use the IPA-B at [2].
