Update of documentation of autoremove command

No description provided.

Installonly packages are once more mentioned as those not affected by autoremove command in dnf history userinstalled description:

dnf/doc/command_ref.rst

Lines 800 to 806 in 96f8d79

	``dnf history userinstalled``
	Show all installonly packages, packages installed outside of DNF and packages not
	installed as dependency. I.e. it lists packages that will stay on the system when
	:ref:`\autoremove_command-label` or :ref:`\remove_command-label` along with
	`clean_requirements_on_remove` configuration option set to True is executed. Note the same
	results can be accomplished with ``dnf repoquery --userinstalled``, and the repoquery
	command is more powerful in formatting of the output.

I think this command also does not do any special handling for installonly packages and the documentation should be updated accordingly.

[j-mracek]

I think that formal description was valid in past. I remember that DNF had a problem in inheritance of kernel reason therefore it somehow mark all installonly packages as user installed or unknown. Hopefully the issue is gone.

[m-blaha]

Thank you!

[j-mracek]

Anyway I have a bad news. DNF does not keep reason of installonly packages. But I have to doublecheck

[j-mracek]

I tried following:
Note: Issue confirmed with standard dnf

# dnf repoquery --installed kernel* --qf="%{name} %{reason}"
kernel user
kernel-core user
kernel-headers unknown
kernel-modules user
kernel-modules-core user
kernel-modules-extra dependency
kernel-srpm-macros dependency

# sudo dnf upgrade kernel*

I did a quick test on fresh F39 virtual machine where it seems OK. But your case doesn't look all right, indeed.

But still - we do not plan to change autoremove command to protect installonly packages, do we?
I'd like to merge this doc PR and file a new one to investigate kernel reasons.

[m-blaha]

Please do not merge it till the installonly packages reason issue is properly investigated.

[j-mracek]

The trigger of the issue with reasons is removal of one of the installonly packages.

[m-blaha]

@j-mracek I think this is good to go now. Any complaints against removing Blocked label and merging?
