Yeah, it's just that every now and then there might be some package removed and
then added again fixed but we have higher chance of finding that out since we
check them more often than on a workstation. It happens with Fedora as well
sometimes, it's just a matter of how fast it gets fixed.

That was my suggestion - adding this in libvirt CI, so that it is fixed across
all projects. I'll propose the patch and we can discuss there, so that other
interested parties know about the potential change as well.
And dnf+yum have such option too, so I would use that as well, not sure about
the others though.
