Users of OpenSHift Origin require CRI-O 1.10 right now. But Kubernetes
users want to try out the latest packages for kubernetes 1.11 which
would require CRI-O 1.11. Origin might not be ready to move to
Kubernetes 1.11 for a while.
Bottom line we want to be able to ship CRI-0 1.10.* and CRI-O 1.11.*
releases in the same Fedora 28.
I believe this is what Modularity was designed to fix.
Can I do this with Modularity? If I can how do I use fedpkg to make
this happen?'
Yes you can, we can help you get set up in #fedora-modularity on Freenode if you like.
