this is what i did for -current if using PXE boot.

The libstand/bootp.c was modified to imports the dhcp tags into the kernel
environment, I then 'invented' rc.conf[0-9], i.e, in the dchpd.conf:
	option FBSD.conf-path="fs-01:/share/conf";

	option FBSD.rc-conf0 "rc.conf";
	option FBSD.rc-conf2 "rc.ws-5.2";
	...

then i added this code to /etc/rc.d/initdiskless:

confpath=`kenv conf-path`
if [ "$confpath" ] ; then
    if [ "`expr $confpath : '\(.*\):'`" ] ; then
        echo Mounting $confpath on /conf
        mount_nfs $confpath /conf
        chkerr $? "mount_nfs $confpath /conf"
    fi
fi

eval `kenv -s -c rc.`
rm -f /etc/rc.conf /etc/rc.conf.local
for fc in $conf0 $conf1 $conf2 $conf3 $conf4 $conf5 $conf6 $conf7 $conf8 
$conf9 rc.conf.$hostname
do
    ho=`expr $fc : '\(.*\):'`
    fl=`expr $fc : '.*/\(.*\)'`
    if [ "${ho}" != "" ]; then
        mp=`expr $fc : '\(.*\)/.*'`
        mount_nfs $mp /mnt > /dev/null 2>&1
        if [ -f /mnt/$fl ]; then
            echo "# from $fc /mnt/$fl" >> /etc/rc.conf
            cat /mnt/$fl >> /etc/rc.conf
        fi
        umount /mnt > /dev/null 2>&1
    elif [ -e /conf/$fc ] ; then
        echo "# from /conf/$fc" >> /etc/rc.conf
        cat /conf/$fc >> /etc/rc.conf
    fi
done
