why driftfile is not on Fedora 32 ?

[Cătălin George Feștilă]

The chronyd working
[root@desk mythcat]# systemctl status chronyd
● chronyd.service - NTP client/server
     Loaded: loaded (/usr/lib/systemd/system/chronyd.service; enabled;
I don't find the driftfile command , why ?
[root@desk mythcat]# driftfile /var/lib/ntp/drift
bash: driftfile: command not found

[john@HP_Box ~]$ cat /var/lib/chrony/drift
             6.003813             0.029500
[john@HP_Box ~]$

That's in el7; F31 is similar.

Probably because ntp isn't installed, chrony is a different
package. You can install ntp from the repos (but turn off
chrony before trying to run ntp).

It looks to me as if that 'driftfile' reference is just defining the 
location of the file that holds the offset and drift rate.  It isn't a 
command, it's a 'directive' for chrony.conf.

man chrony.conf

The chrony has that file.
... for ntp feature, the folder /var/lib/ntp/ is empty even the ntpd is
working.
I will use chronyd, but is this a real problem with ntp feature?

First of all, chronyd and ntpd are both NTP implementations.  You can run either one, but not both.
By default, fedora installs and uses chronyd.

If you wish to run ntpd instead of chronyd you should do....

systemctl --now disable ntpd
systemctl --now enable ntpd

You should then see something like....

systemctl status ntpd
● ntpd.service - Network Time Service
     Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor preset: disabled)
     Active: active (running) since Sun 2020-08-16 16:24:43 CST; 1h 5min ago
    Process: 1965 ExecStart=/usr/sbin/ntpd -u ntp:ntp $OPTIONS (code=exited, status=0/SUCCESS)
   Main PID: 1967 (ntpd)
      Tasks: 2 (limit: 1327)
     Memory: 1.4M
        CPU: 356ms
     CGroup: /system.slice/ntpd.service
             └─1967 /usr/sbin/ntpd -u ntp:ntp -g

Aug 16 16:26:01 f32x.greshko.com ntpd[1967]: Soliciting pool server 2001:418:8405:4002::3
Aug 16 16:26:01 f32x.greshko.com ntpd[1967]: Soliciting pool server 2607:fcd0:100:8203::ba91:df54

Then take note of the man page for ntpd.  And you'll find....

the drift file is automatically updated once per hour and is available to initialize the frequency
on subsequent daemon restarts

This means that ntpd must be running for 1 hour before the drift file is created/updated.

Note that I started ntpd at 16:26:01.  At that time no drift file existed.  But then....

[root@f32x ~]# ll /var/lib/ntp/
total 4
-rw-r--r--. 1 ntp ntp 8 Aug 16 17:24 drift
[root@f32x ~]# cat /var/lib/ntp/drift
-19.732

Ah.....typo...

systemctl --now disable chronyd
systemctl --now enable ntpd
