Re: Building VM images for Copr builders

[LEO PUVILLAND]

I have looked at Packer and it looks like it could be used for this. Not
sure how koji works with kickstarts but would love to check it out! On the
authorization logistics side, I'm not the right person to talk to, but if I
could help in any way that would be great.
Thanks,
Leo
