in rc.diskless1 is where the decision is made about /etc, /tmp, /var.
the mount is done some lines before the test.
i guess a first run could be made, before the actual mount:
...
echo "Interface ${bootp_ifc} IP-Address ${bootp_ipa} Broadcast ${bootp_ipbca}"
for i in ${bootp_ipbca} ${bootp_ipa} ${hostname} ; do
if [ -d /conf/${i}/etc ]; then
if [ -r /conf/${i}/etc/rc.conf ]; then
. /etc/defaults/rc.conf
...
IMHO, the solution is a bit of klduge :-), and sort of breaks the KISS
principle.
