kernel-core pulls linux-firmware

[Reindl Harald]

Hi

where is this dependency from?

after confirm you can happily "yum remove linux-firmware" without
any problems and the next kernel update pulls it again which is
not how a normal dependency works because it would not allow
to uninstall the dependency without remove the pulling package

hence why i have on our virtualized infrastructure for years a empty
meta-package with provides/obsoletes but given now that we have
"kernel-core" and "kernel-drivers" this dependecy should be only pulled
only by "kernel-drivers"

That's why it's Requires(pre).

No.  The kernel-core package contains drivers that require firmware in
linux-firmware.  I'm not dropping that dependency.  Your existing
solution should continue to work.

thanks for clarification and the hyperfast feedback
anyways - thank you for your great work on Fedora kernels!

i am fine with my workaround while my repo-strcuture needs some optimization
to have that package in a own private repo only consumed by virtual machines,
currently it's excluded here and there to not hit phyiscal machines

by not knowing that much of kernel package internas i thought that could
have been a piece better targeted for the new sub-package
