Thanks a million for your time replying to my query. I honestly appreciate
it a lot.

I will try this thank you.

Just some feedback from my side, so we have a smart NIC that allows a
customer to select a distro going on the NIC itself (providing various
custom offload flavors).


For the first wave, I generate custom images based on Ubuntu and CentOS, so
I would love for these rootfs images to be released to some deterministic
URL location so that I can generate images with a script. Something along
the lines of what was done for 7.3 - the rootfs was available next to the
ISO images, but no longer the case with 18.04 (

(We do eventually plan proper EFI boot support which will allow ISO support
in some shape or form, but not right now).

Thank you for all the effort in supporting the development community.
