# The previous multipath-tools.prerm maintainer script did not stop the
# multipathd.service unit, therefore it needs to be stopped here for this
# specific upgrade case.
# "systemctl daemon-reload" is specifically not being called before
#  deb-systemd-invoke because:
#   a) it will be called later in the script, before multipathd.service is
#      started, so let's not call it twice
#   b) it has system-wide effects, like running all systemd generators again
#   c) we don't really need the new multipathd.service unit file to stop the old
#      running daemon. In fact, one could argue it's more correct to use the old
#      unit file to stop the old daemon.
# This approach will generate a one-time warning that can be ignored.
