This is my configuration:

Start script:

[/etc/init.d]$ cat chrony
#!/bin/sh
#
# Start chrony

[ -r /etc/default/chrony ] && . /etc/default/chrony

case "$1" in
  start)
        printf "Starting chrony: "
        chronyd $CHRONY_ARGS && echo "OK" || echo "FAIL"
        ;;
  stop)
        printf "Stopping chrony: "
        killall chronyd && echo "OK" || echo "FAIL"
        ;;
  restart|reload)
        "$0" stop
         sleep 1
        "$0" start
         ;;
  *)
        echo "Usage: $0 {start|stop|restart}"
        exit 1
esac

exit $?

The file /etc/default/chrony:
[/etc/default]$ cat chrony
CHRONY_ARGS="-s -r -f /home/user/etc/chrony.conf"

The file /home/user/etc/chrony.conf:
[~/etc]$ cat chrony.conf
pool pool.ntp.org iburst offline maxdelayratio 2

driftfile /var/lib/chrony/drift
makestep 1.0 3
rtcfile /var/lib/chrony/rtc
rtconutc
rtcautotrim 30

dumpdir /var/run/chrony

Is it allowed to stop chronyd with "killall chronyd" or is there a better way?

The system is running on 32 bit ARM and was created with buildroot.

Any help would be greatly appreciated!

Subject: Restarting the chrony service brakes chrony

I have a strange problem: When chrony is started after boot all works fine.

chronyc --version
chronyc (chrony) version 4.1 (-READLINE +SECHASH +IPV6 -DEBUG)

After 5 min:
chronyc sources

^? cloud.discloud.biz            2   6     3    13  +2145us[ +729us] +/-   26ms

Now I restart chrony
sudo service chrony restart
and I get after 1 min:

And after 2min

^? aardbei.vanderzwet.net        0   6     0     -     +0ns[   +0ns] +/-    0ns

I mean, I can ping the time servers:
ping nts1.time.nl
PING nts1.time.nl(nts1.time.nl (2a00:d78:0:712:94:198:159:11)) 56 data bytes

Any idea why chrony stops to work after a restart of the service?

Or how to debug that further?
