If chrony configuration is deferred, we should at least extend http://www.freeipa.org/page/NTP_Server with instructions how to configure chrony instead of ntpd.

Closer look gives us few more facts:

• chrony can act as a server too. (http://chrony.tuxfamily.org/manual.html#Overview)
• chrony does not support public-key cryptography. ntp does. (http://chrony.tuxfamily.org/manual.html#Chrony-compared-to-other-programs)
• Configuration of both (ntp and chrony) may be accessed/edited using augeas. (https://github.com/hercules-team/augeas/tree/master/lenses)

I believe we should discuss and triage this ticket again.

Constrains for Atomic should be also checked.

Requires for containers. People are also asking about it.

Ticket has been cloned to Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1206608

This is still work in progress. Given how close we are to 4.2 GA, I am postponing this one.

This RFE is no longer critical, RHEL downstream stopped requesting this one for immediate future.

Some aspects of ntp are hard to debug/notice in ipaclient-install.log.

When doing this change it would be nice if it would contain these improvements:

• cleanly tell why the time service is not configured because of other time service. E.g. right now if chronyd is configured initial time sync/ntpd configuration is not done. The fact why it is not done is not clearly reported in the log (there is a print in stdout which is not in the log). E.g. add "other time service is configured(ntpd), disabling chronyd configuration)".
• when doing initial sync, report the ntp server for each attempt in a log. Right now this could be only seen in ntpd output when ipa-client-install is run with -d option(enables ntp debugging).

the comment above is based on experience with bz 1255102

FreeIPA 4.2.1 was released, moving to 4.2.x.

shall we also remove rpm dependency for 'ntp' from ipa-client?

Is this a dup of #7024?

The ntpd has been deprecated in FreeIPA upstream.
https://pagure.io/freeipa/issue/7024
https://github.com/freeipa/freeipa/pull/1535

Changes are described in design page https://www.freeipa.org/page/V4/ntpd_deprecation/chronyd_support
Closing as fixed.
