The zfs-fuse package (which is a dependency of the virtualization stack) installs /etc/cron.weekly/98-zfs-fuse-scrub, which will no longer work in F34 because we are removing cronie from the default install. Ideally, this would use a systemd timer unit instead. (Alternatively, you could require cronie-anacron, but please don't, because zfs-fuse is a dependency of the virt stack that would pull cronie back in.)
