[systemd-devel] GuessMainPID=no required to make daemon reload work

Hi Кирилл,

Thanks.

To get it right I have to take care of two cases of SIGTERM in the old daemon:

a) the new process checked it's config, everything is ok, and it sent the 
SIGTERM to the old daemon

b) the new process is still checking the config and in this moment someone else 
(like systemd) is sending a SIGTERM to the old daemon (it is still considered 
the master).

So I think I have to look who is sending the SIGTERM and act accordingly.

So unless someone else has a better idea I'll try this approach and report 
back.

Kind regards,

Gerd
