This happens after you've built kernels the ISC way (kconfig) and the
AT&T way (usually performed by an installable device driver).  As
you discovered later, you have to remove /etc/conf/cf.d/unix manually,
or change the scripts.  We ship our software the AT&T way, since
it is the most portable, and I suspect that most vendors will do
the same.  The ISC way has advantages, though, and I wish that
the vendors had come to a mutually agreeable merge, rather than
trying to simultaneously support both (actually three, if you count SCO).

There's another bug (AT&T created; not yet fixed in ISC) you can run into
that may cause similar problems.  Here is the info I sent to ISC
about the bug.  AT&T UNIX SVR3.2 also has this bug.  If you make
these changes to your scripts now, you won't get a surprise later.

SUBSYSTEM:	installpkg

VERSION:	2.0.2 (possibly, likely, in earlier releases)

DATE:		11/11/89 (Acked 11/19)

SUMMARY:	Can't install two installable packages which have
		rc and/or sd scripts.

FILES:		/etc/conf/bin/idmkenv

DESCRIPTION:
		Starting at line 24, the code looks like this:

	if [ -f /etc/conf/rc.d/* ]
	then
		for rc in /etc/conf/rc.d/*
		do
			ln $rc /etc/idrc.d
		done
	fi
	if [ -f /etc/conf/sd.d/* ]
	then
		for sd in /etc/conf/sd.d/*
		do
			ln $sd /etc/idsd.d
		done
	fi

		Both "-f" tests will fail if more than one script exists
		in these directories.

SEVERITY:
		Urgent.  Third party install packages fail to install
		properly, or break previous installations.

SUGGESTED FIX:
	if [ -d /etc/conf/rc.d ]
	then
		for rc in `find /etc/conf/rc.d -type f -print`
		do
			ln $rc /etc/idrc.d
		done
	fi
	if [ -d /etc/conf/sd.d ]
	then
		for sd in `find /etc/conf/sd.d -type f -print`
		do
			ln $sd /etc/idsd.d
		done
	fi
