Subject: [PATCH 5/5] [debug] Do not remove install-only packages
 (RhBug:1844533)

Running debug-restore command may result in an attempt to remove the
running kernel (in case the running kernel package is not present in the
dump file).
Newly the install-only packages are not removed, only the versions
mentioned in the dump file are marked for installation (the decision on
what versions to keep on the system is done according to
installonly_limit config option).
New option `--remove-installonly` to force removal of those versions of
install-only packages that are not present in the dump file is
introduced.

-Writes system RPM configuration to a dump file and restore it.
+The plugin provides two dnf commands:
+
+``debug-dump``
+    Writes system RPM configuration to a dump file
+
+``debug-restore``
+    Restore the installed packages to the versions written in the dump file. By
+    default, it does not remove already installed versions of install-only
+    packages and only marks those versions that are mentioned in the dump file
+    for installation. The final decision on which versions to keep on the
+    system is left to dnf and can be fine-tuned using the `installonly_limit`
+    (see :manpage:`dnf.conf(5)`) configuration option.
 
 .. note:: DNF and Yum debug files are not compatible and thus can't be used
           by the other program.
