[Bug 1447142] Re: systemd: ntpdate is started too soon (before the network)
Laurent,
Thank you for your reply.
> I guess that Ubuntu systems with ntp installed would boot a little
faster if ntp was not doing useless work by getting started before the
network is fully up.
That's reasonable, though then this bug should be of low importance I
think, as the impact to users is relatively small.
> Perhaps, but timesyncd is not activated by default.
Ah. I had forgotten before, but now I remember that I was told that
timesyncd is automatically deactivated if ntp is installed.
> While timesyncd is probably a fine alternative to ntp, this is a bug
in ntp and Ubuntu would be a better system with this bug fixed (or ntp
removed and timesyncd activated by default).
Actually ntp isn't installed by default, and thus I believe that
timesyncd is activated by default, but isn't on your system because ntp
is installed.
I accept that prior to Vivid timesyncd wasn't an option, so it was
perfectly reasonable for users to install ntp manually, and then after
upgrade if this is broken then that is a bug.
But I think the breakage is just the suboptimal attempt to sync time at
boot, right? If time with ntp stays synced later without issues, then
I'll set Importance to Low on this basis. If I'm wrong in my
understanding then we can change this.
** Changed in: ntp (Ubuntu)
Importance: High => Low

Status in ntp package in Ubuntu:

Bug description:
Here is what I see in journalctl: ntpdate cannot do DNS resolution
because NetworkManager has not finished configuring the network
interface.
