As you see I don't do this :)

In 2.2, you have a construct like so:

# for example:
#
#       network_interfaces="ed0 sl0 lo0"
#
#       ifconfig_ed0="inet 10.0.0.1 netmask 0xffffff00"
#       ifconfig_sl0="inet 10.0.1.0 netmask 0xffffff00"
#       ifconfig_lo0="inet localhost"
#       ifconfig_ed0_alias0="inet 10.0.2.1 netmask 0xffffff00"
#       ifconfig_ed0_alias1="inet 10.0.2.2 netmask 0xffffffff"
#       ifconfig_ed0_ipx="ipx 0x1234"
#
# Alternatively, /etc/start_if.${network_interface} is run if it exists.
# This script can be used as an alternative to the ifconfig_<xxx> lines.
#

This is a comment in sysconfig on my box.
