[Serusers] Re: [Users] How to start ser on boot? how to monitor it?

[Jan Janak]

One more thing -- if you want to make SER restarts really reliable then
you can use -G command line option. SER would write the process group of
all SER processes into the specified file. You can then pass this value
as negative number to kill and it will kill all ser processes.
