Fixed In Version: dnf-4.4.2-2.el8
Doc Type: Enhancement
Doc Text:
.The `protect_running_kernel` configuration option is now available. With this update, the `protect_running_kernel` configuration option for the `dnf` and `microdnf` commands has been introduced. This option controls whether the package corresponding to the running version of the kernel is protected from removal. As a result, the user can now disable protection of the running kernel.

I am sorry but the protection of packages is a feature of dnf. For your user case I would recommend to use "rpm -e kernel kernel-core kernel-modules" or "rpm -e $(dnf repoquery kernel* -q --installed)" commands for a kernel case. To disable protection it also helps to use "--setopt=protected_packages=''", then the systemd could be removed, but not a running kernel. Hope that it helps.

I see bug. And bug is: DNF behaves differently in various namespaces.
Action of DNF is not consistent. For specific example check original bug-report.
We have ci-system. Where main tools id DNF. Of course we can set various `special conditions`. But this is local solution. And more and more people will bump into this.
Please make aware DNF of different namespaces.
Currently DNF is not ready to work in containers.

We could use systemd-detect-virt to detect if we're inside a container.
Also if we're working with an installroot that is different (realpath!) to '/' we could also allow removing kernel.
