Basically, this is just a simple name change. People were historically
confused by the "cpio floppy", having no clear idea as to what it was
(even if they knew what "cpio" stood for) given that the name gives
one absolutely no indication as to what it's FOR. It's about as content
free as calling it a "data floppy". Root floppy isn't much better, but
it's got some historical weight (Linux divides their set into boot and
root floppies) and is reasonably descriptive for a floppy that comprises
the beginnings of a stand-alone root filesystem.
