[Tutor] Python Daemon

That's not true, at least not with my definition of daemon, basically a
process that is left running.  Just start the process in the background
(with an &, like "python script.py &") and exit the shell.
Perhaps with older shells you'll have to run it through nohup or something,
but I don't know.

Or put it in you system startup scripts, for example /etc/rc.d/rc.local on
Red Hat 6.2 and the like.  On debian, you'd make a script in /etc/init.d/
and link it in /etc/rcN.d/ where N is between 2 and 5.  This will work nicely
on Red Hat too, except it's /etc/rc.d/{init.d,rcN.d} on older versions than
7.0.  If you have more questions about GNU/Linux startup scripts, you can of
course send them to me privately or to your local LUG mailing list, but I
guess it's a bit offtopic for tutor...

Anyway, my point is that fork()ing should not be necessary.

Peace,
