Ah, how memory comes flooding back after the message has been sent! Sigh.
/etc/rc did have a tty associated with its process and therefore could
inform the operator that various daemons and subsystems had been started. It
was only the subprocesses that were backgrounded that had to write any
messages to a file or to /dev/null (or, possibly, to /dev/console).
