Oh, good catch. Also, that's a funny one.
So, you can't remove the currently running kernel-core. As expected.
BUT, you can remove the currently running kernel/kernel-drivers.
That's good because we want those packages to be optionally
(un)installable but bad because if you actually require
kernel-drivers, well, it's obviously bad.
Not sure if there's a good fix to this. We'd either limit people to
only being able to get rid of kernel-drivers with some dancing around
with different kernel versions and some rebooting, etc. Or we allow
people to remove the kernel-drivers of the running kernel which
defeats the purpose of the protection. #leSigh
Oh (#2), and here, dnf actually differs from yum. dnf protects *none*
of the packages. So that's definitely a bug and I'll report it once we
know exactly what behavior we want (so that yum and dnf will do the
