Centos 7.4 - Re: [chrony-users] Delaying postfix until chronyd gets the time

I have been following your thread on chrony 3.1 coming out in Centos 7.4.

How does this impact the hacks we did to deal with no battery rtc on many arm boards?

However, you could force chronyd to ignore the RTC by setting

rtcdevice /dev/doesnotexist
Where do I get the command, rtcdevice?  It is not on my system. Then how do
I run it?  Do I add an ExecStartPre= to the chronyd.service file?
It should be in chrony.conf. It specifies the path to the RTC device,
which is /dev/rtc by default.

And do I create a /etc/sysconfig/chronyd with the single line:

Yes. If there are multiple options, I think they need to be in double
quotes, e.g. OPTIONS="-s -4".
