That sounds reasonable. Are the Vagrant kickstarts there synced or 
merged with what we have on GitHub? What about the issues and pull 
requests, would everything move to bugs.c.o.? It would make sense not to 
have two places where we develop and collaborate. We currently also have 
GitHub hooks that automatically build and test new images on each 
incoming pull requests, is there an equivalent on Pagure (or GitLab, 
there was some talk about migrating away from Pagure).

I would prefer to have everything fully automated for the Vagrant 
images, from image building and testing, to uploading, signing and 
publishing on Vagrant Cloud. That way, we can simply schedule this on 
the last day of each month and have regular releases (or 28th of each 
month if it's easier with cron).

I can already build images locally using Packer and the same kickstarts, 
so I can see if a kickstart change introduces some issues in the 
generated images (this doesn't let me see if pykickstart with ignore 
something in my kickstart, like it happened with %addon in centos/7 for 
a long time).

The Vagrant images are quite mature, there are barely any kickstart 
changes going on. I guess 8.2 will be released relatively soon, perhaps 
we can build and publish centos/8 then for all hypervisors (we're 
already so far behind with the 8 images - or would people prefer 8.1 
images right now, and then 8.2 when released?).

Would it make sense to also offer Vagrant images for CentOS 8 Stream?

Best regards,
