Ok, I guess I should drop that idea. Even if I'm not sure I see why it
can't be done (at least on this machine, there's a setsid program that
should be usable from a script).

Another case is if the deamon is started directly by init (listed in
inittab). In this case it's a bad idea to fork and let the parent
exit. Perhaps
if ( (getppid() != 1) && fork() ) exit(0);
should do that trick.

Somebody else just offered to write the code. So we'll see what
happens.
