[systemd-devel] SIGHUP to systemd

[prashantkumar dhotre]

Hi
What happens when SIGHUP is sent by some service to systemd (PID 1 ) ?
I see below lines in journalctl logs

 systemd[1]: Received SIGHUP from PID 27128 (myservice).
 systemd[1]: Reloading.
 systemd[1]: Configuration file /lib/systemd/system/xyz.service is
marked executable. Please remove executable permission bits.
Proceeding  anyway.

Does SIGHUP ends up killing any process ?
Where do I see code for handling SIGHUP in systemd src (file/function) ?

Thanks
