Quick question which should get a quick answer. I am daemonizing
a process using the standard steps as lifted from inetd.c.

	fork()
	close(open descriptors)
	open("/")
	dup(0) 
	open("/dev/tty")
	ioctl(tty,TIOCNOTTY)

I understand all these steps except the open("/") and the subsequent
dup() of the resultant file descriptor. Can somebody e-mail the reasons
for and effects of this step? I've looked through every manual and man 
page that might remotely help and came up with nothing.

Thanks.
