Upstream seems to disagree with the IP_FREEBIND implementation, as per https://bugzilla.samba.org/show_bug.cgi?id=13463. The reason behind it is that the daemon should fail for invalid ip addresses.
Adding After=network-online.target is frowned upon by systemd upstream. Following up with upstream to exit with a non-zero code seems to be the path forward here. ** Tags added: server-todo -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to rsync in Ubuntu. https://bugs.launchpad.net/bugs/1774788 Title: Daemon won't start at boot up (18LTS fully patched) Status in rsync: Unknown Status in rsync package in Ubuntu: Triaged Bug description: By adding the 'address=' option to the /etc/rsyncd.conf file, the daemon fails at boot.
