- # Due to reasons [1], the old python2 matrix-synapse package will not stop the
- # service when the package is uninstalled. Our maintainer scripts will do the
- # right thing in terms of ensuring the service is enabled and unmasked, but
- # then do a `systemctl start matrix-synapse`, which of course does nothing -
- # leaving the old (py2) service running.
- #
- # There should normally be no reason for the service to be running during our
- # preinst, so we assume that if it *is* running, it's due to that situation,
- # and stop it.

- # [1] dh_systemd_start doesn't do anything because it sees that there is an
- # init.d script with the same name, so leaves it to dh_installinit.
- #
- # dh_installinit doesn't do anything because somebody gave it a --no-start
- # for unknown reasons.
