Please do a new release of pykickstart for F-26+ to include the fix for https://github.com/rhinstaller/pykickstart/issues/148 to unblock sharing image kickstarts across all architectures.
Done: https://koji.fedoraproject.org/koji/buildinfo?buildID=877649
Thanks, please file an update in bodhi for the new release too.
We'll also need it on the builders so any chance of a build for F-25?
