Later to be combined in SRU Template Reasoning - snippest updated from my old commit log to be readable here in the bug:
Cases of the codepath (Ubuntu Delta) that we intent to remove: Case 1 - bug that it meant to fix initially: - ntpd comes up and can not find peers to associate with - an interface comes up - stop ntpd - sync time once with ntpdate-debian - (re-)start ntpd (now able to find its peers, but it will throw away what ntpdate just has set, so not worth) Case 2 - more common case: - ntpd comes up normally - the admin brings interfaces up/down rather often - ntp is restarted very very often due to this for no reason => That behavior is close to a bug on its own, which is the reason for bugs like https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=823533 Case 3 - still more common - ntpd is installed but disabled (for whatever reason) - all is fine on any ifup/down - one installs ntpdate, maybe even without realizing due to a depends - now on the next ifup ntpd (or openntpd) will be started By dropping this section we fix it for Case 2 and Case 3. Users of Case 1 still have no impact - their call to ntpdate will refuse to change things as there is a running ntp. Like: $ /usr/sbin/ntpdate-debian 20 Jun 08:02:32 ntpdate[519]: the NTP socket is in use, exiting And as outlined in Case 1 the running ntp would resync over it anyway. If there was nothing running at all - well then the sync works and things are fine still. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1593907 Title: ntpdate startup routine prevents ntp service from launching up on Ubuntu 16.04 server on system boot; manually starting ntp service works: [FIX in DESCRIPTION], just need to apply it and release a new version To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/1593907/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
