Can't get pidfile to work in rc script

[Lee Brown]

I'm trying to get 2 separate sshd's running.  I've created
/etc/rc.d/sshd_alternate but it always uses /var/run/sshd.pid and not
/var/run/sshd_alternate.pid.  I tried

sshd_alternate_pidfile="${pidfile}"
and
procname="sshd" / procname="/usr/sbin/sshd"

to no avail.  Can somebody provide some assistance, I'm sure this is simple
but I just can't fathom it.

TIA

#!/bin/sh

# PROVIDE: sshd_alternate
# REQUIRE: LOGIN FILESYSTEMS
# KEYWORD: shutdown

. /etc/rc.subr

    echo "Performing sanity check on ${name} configuration."
