Indeed, and in this case I think support by an additional tool
like sgivol is fine.

Exactly - it adds an ffs partition (with padding) behind the iso9660
part and uses a spare sector early in the image (ignored by iso9660)
to store the sun label. Here too it is fine to use a postprocessing tool

Ok, so this differs from both sparc64 and sgimips significantly. Now, what is
the purpose of the change starting this thread if it only does the minor step
but leaves out the complex one that realy fits well into makefs?
