# Begin refresh systemd units and clean up possibly obsolete systemd units
# The following is a generic way how to refresh and/or clean up systemd units.
# A systemd unit may need a refresh after updating a package when the new package
# had installed a changed systemd unit file for an enabled systemd unit.
# A systemd unit may become obsolete by updating a package (see bnc#904215).
# A systemd unit is considered to have become obsolete when the systemd
# symlink /etc/systemd/system/.../unit_name -> /path/to/unit_file is broken.
# When during package update the new package does no longer provide a unit file
# then the systemd symlink becomes broken after the files of the old package
# had been actually removed by RPM.
# According to /usr/share/doc/packages/rpm/manual/triggers and according
# to https://en.opensuse.org/openSUSE:Packaging_scriptlet_snippets#Scriptlet_Ordering
# and http://fedoraproject.org/wiki/Packaging:ScriptletSnippets#Scriptlet_Ordering
# from the new package only "posttrans of new package" is run after "removal of old package"
# so that the new package must do the clean up as RPM posttrans scriptlet.

    # Enforce systemd to use the current unit file which is usually the unit file of the new package
    # but also in case of custom units (that use other unit files) a "reenable" won't hurt because
    # "reenable" does not implicitly stop a running service which is "the right thing" because
    # a RPM package installation must not automatically disrupt (restart) a running service.
    # Using "--force reenable" is essential to clean up possibly conflicting/broken symlinks.

    # see https://bugzilla.opensuse.org/show_bug.cgi?id=904215#c34
    # so that first the unit has a clean state and then it is set back to disabled (as it was before).
    # If a disabled systemd unit has become obsoleted, "systemctl --force reenable" will clean it up
    # which means the unit gets removed and the subsequent "systemctl disable" will do nothing.
