zfs module doesn't work in latest kernel (6.2.9-100.fc36) and "dnf remove zfs" tries to remove dkms, libvirt etc.
System information
Distribution Name | Fedora Distribution Version | 36 Kernel Version | 6.2.7-100.fc36 Architecture | x86_64 OpenZFS Version | zfs-2.1.9-1
Describe the problem you're observing
Since zfs module doesn't work in the latest 6.2.9-100.fc36 kernel anymore I wanted to remove it, since I don't need it.
Trying to reinstall the latest kernel-core again results in the following:
Building module:

#14658, will be fixed in 2.1.10 whenever that comes out.
And as far as why it's removing everything and the kitchen sink, I'd need to look more, but at a glance, it seems like libvirt-daemon-kvm depends on something providing zfs, and then it's just cleaning out dependencies of libvirt-daemon-kvm and zfs that are no longer used, recursively, which is not a bug.
Yes but it also tries to remove qemu-system-x86 which is a no go. And isn't dkms needed by the proprietary nvidia drivers and a lot other stuff?
Well, once you've uninstalled all libvirt's other dependencies, nothing that wanted qemu remained.
And I can't speak to what else is on your system and registered in the package manager, but if you installed the NVIDIA drivers not in RPMs, it's not going to know you need that for that, though I think you can manually mark it as needed and not just a dependency.
I haven't checked zfs package removal, but this problem really exists with the latest Fedora kernel (6.1.9-200), but on Fedora 37. Time for kernel downgrade...
Since 2.1.10-1 my latest kernel 6.2.9-100.fc36 boots correctly. But now there is another problem. I was testing other custom modules and wanted to restore all default kernel modules as I always did before like this:
sudo rm -v /lib/modules/$(uname -r)/kernel/fs/ufs/ufs.ko*
koji download-build --rpm kernel-core-$(uname -r).rpm
sudo dnf -y reinstall kernel-core-$(uname -r).rpm
But the default module didn't appear at all this time, I suspect it has to do with the zfs dkms script, here the output:

Fertig!
It seems like it thinks you have DKMS packages for 2.1.9 and 2.1.10 both configured. What does dkms status say? What does rpm -qa | grep zfs say?
@rincebrain I have upgraded to the new 6.2.10-100.fc36.x86_64 now and already running it. But dkms status still mentions the older version it seems:
Error! Could not locate dkms.conf file.
File: /var/lib/dkms/zfs/2.1.9/source/dkms.conf does not exist.

That seems like it still thinks 2.1.9 exists in DKMS's "someone ran dkms add on this" list but it can't find the files for it. Oof. dkms remove -m zfs/2.1.9 should convince it otherwise, possibly with some force flag if need be, without removing 2.1.10.
sudo dkms remove -m zfs/2.1.9 wasn't the solution, just output this:
Module zfs 2.1.9 is not installed for kernel 6.2.10-100.fc36.x86_64 (x86_64). Skipping...
Module zfs 2.1.9 is not built for kernel 6.2.10-100.fc36.x86_64 (x86_64). Skipping...
Removing this directory fixed it though: sudo mv /var/lib/dkms/zfs/2.1.9 .
My suspicion still was wrong, the ufs module isn't even contained in kernel-core-$(uname -r).rpm but in kernel-modules-extra-$(uname -r).rpm
It is in-tree, just recompiled it with different config to enable the write option.
