I'm thinking of a "two stage procedure" that can be implemented
well with /etc/rc.conf. Stupid idea, I know, but it should work,
allthough you could make it more tidy:
# First create /etc/ifconfig.conf if not already there
if [ ! -f /etc/ifconfig.conf ]; then
echo "#!/bin/sh" > /etc/ifconfig.conf
ALIAS=0
while [ ${ALIAS} -lt 125 ]; do
echo 'ifconfig_rl0_alias${ALIAS}="inet 80.252.2.`expr ${ALIAS} + 4` netmask 255.255.255.255" >> /etc/ifconfig.conf
ALIAS=`expr ${ALIAS} + 1`
done
fi
# Now source it into /etc/rc.conf
. /etc/ifconfig.conf
# Done.
