Description of problem:
At the moment there are two ntp daemons included in overcloud-full images (ntpd and chrony). This is solving in BZ1413754.
Customer would like to use chrony as the only ntp daemon in a future. This would be aligned with default RHEL OS installation, which is (as far as I know) chrony, in RHEL7+.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install fresh overcloud with default config
Both ntpd and chrony are installed
Only chrony installed and configured.
So we fixed the ntp/chrony issue but this request to switch from ntp to chrony would be an RFE. I know there is also an upcoming request to support PTP https://review.openstack.org/#/c/483227/
