Public bug reported:
[impact]
the knockd systemd service file is configured to start knockd
After=network.target, however the systemd 'network.target' only means
network configuration has started, not completed; the interface(s) that
knockd is configured to listen on may not even be up yet. In that case,
starting knockd fails.
[test case]
install, configure, and enable knockd on a system. reboot the system,
and check the logs for knockd errors about the interface not being up.
verify knockd is not running.
[regression potential]
changing the systemd service dependency to use network-online instead of
network delays when knockd starts, and regressions would be related to
knockd not running before the network was fully configured, or not
running at all if systemd failed to ever reach network-online target.
[other info]
this requires the knock systemd service file fix from bug 1799697 also,
since the knockd systemd service cannot be enabled at all without that
fix.
this applies only to b/c/d since t/x use upstart for service management,
and this bug is only in the knockd systemd service file.
