Most services can re-load/re-read their configuration file through the command "service xxxx reload", which is usually implemented by "kill -HUP service_pid" .
for NTPD service, "service ntpd restart" and "service ntpd reload" are identical in /etc/rc.d/init.d/ntpd. what's more, "kill -HUP ntpd_pid" command will cause ntpd service to restart.
Hence, if we want ntpd to re-read its configuration file after run-time configuration, do we have to restart ntpd? Is there any way to reconfigure ntpd without restarting it ?
Thanks!!
