Hmm... it mentions that Fedora 31 would be ok for the tests, but
the zram-generator package is not available on Fedora 31:
https://dl.fedoraproject.org/pub/fedora/linux/updates/31/Everything/x86_6...
Assuming that CONFIG_ZRAM is enabled on Fedora 31, you should either
backport zram-generator packages to Fedora 31 or update the test day
page accordingly.
The package is fully backwards compatible, so it would be OK to simply
push the latest version to F31. But there isn't enough time to go
through updates-testing. So I think we should ask people to install the package
directly from koji:
sudo dnf install
https://kojipkgs.fedoraproject.org/packages/rust-zram-generator/0.2.0~rc....
-p`/zram-generator-0.2.0~rc.1-1.fc32.`uname -p`.rpm
