Understanding chrony on the AlmaLinux machine

There are two components in the chrony system. We have chronyd as the daemon and chronyc as the user interface. The chronyd component can run in either client or server mode. First, let's look at the unit file for chonyd.

The chronyd.service file

If systemd detects that either ntpd or systemd-timesyncd is running, then chronyd will fail to start. The ConditionCapability= line indicates that this service runs under a non-privileged account, even though no non-privileged...
