They were originally added because I forked this from a set of descriptions to build generic Fedora x86_64 and ARM images. As for kernel-modules-extra, that's where the ARM Mac kmods live, so it'd be bad to not include it.

I'm not sure why we're not putting the kernel packages under "Asahi Packages" -- as these kernel rpms are located in the Asahi repo.

We're not doing this because it intentionally is supposed to allow either the stock kernel or ours depending on the repo configuration.

So I'm looking at the modules included in
https://download.copr.fedorainfracloud.org/results/ngompa/fedora-asahi-dev/fedora-37-aarch64/05159052-kernel/kernel-modules-extra-6.1.0-0.rc8.105.asahi.fc37.aarch64.rpm

...and I'm not seeing any arm mac-specific kmods there.
Which modules are you referring to?

They were originally added because I forked this from a set of descriptions to build generic Fedora x86_64 and ARM images.

So is there any issue with removing these non-pertinent x86_64 descriptions?

I don't get why we can't just use arch-specific descriptions like this (except for aarch64):
https://github.com/OSInside/kiwi-descriptions/blob/master/fedora/x86_64/fedora-37.0/config.xml

Otherwise, it might give the impression to the casual-user that multiple architectures are supported.

tbh, this is all pretty trivial. Just delete this PR if you feel that nothing needs to change.
