After googing around, here is my first attempt at
I did a successful "systemctl enable myDaemon.service".
"systemctl start myDaemon.service" starts the program,
but as before, it fails "pthread_create(...)". Of
course, it also fails on boot.
"/etc/init.d/myDaemon <start|stop>" still work correctly.
Thanks again for your comments.
