DNF just needs to prevent the upgrade as long as the kmod is not available.
I think that this can actually be enforced through boolean dependencies
nowadays, without requiring any special handling in DNF: the kmod-nvidia
metapackage should not just have a:
Requires: kmod-nvidia-%{latest_kernel_version}
as in the past, but also a:
Requires: (kmod-nvidia-bin > %{latest_kernel_version} if kernel >
%{latest_kernel_version})
where kmod-nvidia-%{latest_kernel_version}:
Provides: kmod-nvidia-bin = %{latest_kernel_version}
Requires: kernel = %{latest_kernel_version}
So this will forbid installing a newer kernel unless there is also a newer
kernel module to go with it (and the Requires in the module enforces that
the versions also have to actually correspond).
