@@ -0,0 +1,18 @@ +Proper time-sync.target support for systemd-timesyncd + +This package essentially just works around + https://github.com/systemd/systemd/issues/5097 + +systemd.special(7) tells us that "All services where correct time is +essential should be ordered after [time-sync.target]". However, +systemd-timesyncd allows time-sync.target to be reached before +timesyncd has actually synchronized the time. This is because it +sends READY=1 as soon as the daemon has initialized, rather that +waiting until it has successfully synchronized to an NTP server. + +It would be trivial to patch timesyncd to wait, but that would +introduce some other problems. + +So, I'm introducing systemd-timesyncd-wait. It is a service that +listens for messages from systemd-timesyncd, and block until it sees a +message indicating that systemd-timesyncd has synchronized the time. |
