Hello again!

Thanks everyone for joining the discussion and for the advice, much appreciated.

To summarize the current situation:
- at the moment it's not possible to build any rpm-based image on ubuntu focal using diskimage-builder with the centos-minimal element;
- so far, we've successfully built the centos8 based ipa-ramdisk using diskimage-builder in ironic-python-agent-builder on centos-8 nodeset, but using the same nodeset also for testing the image (so running devstack) would be very time expensive because of the changes involved;
- during the last ironic meeting, it has been decided to switch to the centos element and give that a try using the ubuntu focal nodeset; main concern about this approach is the final size of the ipa ramdisk, tests are ongoing and it looks promising:

Thanks again!

Riccardo

I expect that would be almost unworkable from within a virtual
machine instance without nested virt acceleration.
