            Log:
            delete all users at the end

When the first user is deleted before the second user is created,
they will have the same UID and the systemd processes will be
confused. The confusion leads to incorrect SELinux labels on
subdirectories of /run/user/<UID>/.

By deleting all users at the end, we ensure that each of
them will have a different UID and their directories will be
labeled correctly.
