Having installed the memphis rpm the invocation of the tcpserver is
controlled by the following file /etc/rc.d/init.d/qmail-qmtpd.init which is
as follows:
#! /bin/sh -
# $INITDIR/qmail-qmqpd.init
# INITDIR is defined below
# Sun Dec 14 1997 XZ <[EMAIL PROTECTED]> v2.3
# chkconfig: 345 84 49

# signal qmail-qmqpd. \
# Makes heavy use of parts of DJB's daemontools package \
# It also relies upon daemontools.functions for 91.04982% \
# of the grunt work.

I think I might be able to figure out how to fix this file so it doesn't
launch a supervised tcpserver with incorrect parameters but it would be
useful to start off with a working one, and then I can try to translate that
into the script.
What does your invocation look like?
It seems to me though that since this script is unmodified from the memphis
rpm that everyone who uses the memphis rpm should have the identical
symptom, or am I missing something?
