In the era of remote work the different terminal connections are used for
testing and debugging linuxptp based solutions. Particularly one of the
setup is based on xterm when a set are HW platforms remotely configured and
linuxptp based SW started. When restart of xterm sessions happens the
linuxptp based SW does not receive any of SIGINT/SIGQUIT/SIGTERM signal and
as result left in unpredictable state which causes automation tests failure
after restart and required reboot to recover.
The Xterm will notify its child process with a SIGHUP ("hangup") before it
exits, hence add registration of SIGHUP handler to fix an issue.
