ntpd should be able to use the new interface after a while (the default interface update is 5 minutes). Have the servers specified in ntp.conf option "dynamic"? No, there is no "dynamic" option, ntp.conf is the standard Fedora version. The problem was compounded by the fact that the default clocksource (tsc) drifted so badly that ntpd never synchronized, so together with the initial failure to set the clock, and resetting the hwclock on shutdown, I ended up with accumulated errors of as much as 45 minutes -- rather unsettling. And no headsup message either except grepping through the log. For dynamic interfaces it's necessary to use the option. Default ntp.conf from the package does that. Hmm, I grepped dynamic in ntp.conf and didn't see it. I'll take a closer look when I get back home as maybe it is under a different name. The install was from the f7 live disk, is it possible that it differed from the full install? system-config-date could overwrite the file, it doesn't support the option yet. (bug #229217) That must be it, because I don't see it. I wonder if ntpd will still synchronize the system clock before starting if it finds the servers later? The initial synchronization done by ntpdate? It's not delayed, so it will not do any synchronization in this case. Does ntpd work correctly when "dynamic" is used? Yes, that seems to do the trick, ntpd came up about 30 seconds after the network. Now let's see what happens if I fiddle with the clock... Sure enough, the dynamic option went away. Ok, I'm closing this as NOTABUG. |
