include statement does not work in chrony.conf

#1

Hi,

recently I updated from chrony 3.0 to 3.1 (chrony-3.1-21.1.x86_64). I am using the include statement in the chrony config file.
After updating the statements in the included file are not included any more.

This is my /etc/chrony.conf:


driftfile /var/lib/chrony/drift
makestep 62 -1
rtcsync
allow
local stratum 7 orphan
maxdistance 6
logdir /var/log/chrony
log measurements statistics tracking rtc refclocks tempcomp
logbanner 100
logchange 0.1
refclock SHM 0 refid GPS precision 1e-1 offset 0.18 delay 0.2
refclock SHM 1 refid PPS precision 1e-9 delay 0.15
include /home/tester/ntp.include

This is /home/tester/ntp.include (Rights -rw-r–r–):

server 192.168.87.95 iburst

chronyc sources lists (GPS is not connected at the moment):

210 Number of sources = 2

===============================================================================
#? GPS                           0   4     0     -     +0ns   +0ns] +/-    0ns
#? PPS                           0   4     0     -     +0ns   +0ns] +/-    0ns

chronyc does not complain :

The server is used when I move the server statement from the include file to /etc/chrony.conf.

Can anyone reproduce the problem?

Thanks!

Update: I updatet to chrony-3.1-21.21.x86_64 but still the same problem.

The problem is caused by the systemd configuration. The option ProtectHome has to be changed to read-only otherwise chrony cannot read from the home directory.

Working chronyd systemd config:
