Dear Maintainer, the wait-online timeout is currently hard-coded, the value of 30 seconds is insufficient in some cases. Example use case: workstation that is turned on at the same time as a router it relies on for connectivity, which takes ~2.5 minutes to boot. The `apt-helper wait-online` (`ExecStartPre` of apt-daily.service) times out before the connection becomes usable and the workstation is typically shut down before the next timer trigger, so effectively unattended-upgrades never runs. Please make the timeout configurable.
