We got to the current place thusly:

 - The initial ramdisk code in Nova-baremetal needed a home other than
a wikipage.
 - And then there was a need/desire to build ramdisks from a given
distro != current host OS.
 - Various bits of minor polish to make it more or less in-line with
the emerging tooling in DIB.

I've no attachment at all to the ramdisk implementation though -
there's nothing to say its right or wrong, and if dracut is better,
cool.

The things I think are important are:
 - ability to build for non-host arch and distro.
 - ability to build working Ironic-deploy ramdisks today, and
Ironic-IPA ramdisks in future
