I haven't worked out which package updates/creates the `/etc/init.d/net.* ` scripts, but I've made a workable (for me) modifications and thought I'd pass it along.
I'm predominantly attached(?) to wireless networks, and I needed a convienent way to inject the essid during the boot process. In keeping with the rest of the Gentoo design, I store the essid in the `/etc/conf.d/net`, and reference the variable from the init script.
Variable added to `/etc/conf.d/net` - essid_$IFACE
Modification to init script - | Code: | #!/sbin/runscript
<snip>>>>>>>>>>>>>>>>>>>>>>>
iface_start() {
local retval=0
setup_env ${1}
checkconfig || return 1
local IFACE="${1}"
ebegin "Bringing ${IFACE} up"
###########################################
if [ -n "${essid_IFACE}" ]
then
local x=""
ebegin " Adding ESSID "
for x in ${essid_IFACE}
do
/usr/sbin/iwconfig ${IFACE} essid ${essid_IFACE} > /dev/null
eend 0
done
fi
##########################################
if [ "${iface_IFACE}" != "dhcp" ]
then
/sbin/ifconfig ${IFACE} ${iface_IFACE} >/dev/null || {
retval=$?
eend ${retval} "Failed to bring ${IFACE} up"
return ${retval}
}
# ifconfig do not always return failure ..
/sbin/ifconfig ${IFACE} &> /dev/null || {
retval=$?
eend ${retval} "Failed to bring ${IFACE} up"
return ${retval}
}
else
# Check that eth0 was not brough up by the kernel ...
if [ "${status_IFACE}" != "up" ]
then
/sbin/dhcpcd ${dhcpcd_IFACE} ${IFACE} >/dev/null || {
retval=$?
eend ${retval} "Failed to bring ${IFACE} up"
return ${retval}
}
fi
fi
eend 0

One key item, set the essid before dhcpcd and the interface will work perfectly (provided you have the correct essid, gotta work on that).
I realize it's a simple plug, but that's why I'm amazed it hasn't already been done. Now, if we could only select/override the network interface during the boot......

It already has - it's just not in portage yet.
My ebuild puts provides an overlay for wireless networking that plugs into Gentoo's net.eth0 script via preup() and predown() functions that net.eth0 provides.
It scans for AP's and then configures wep and networking accordingly
Example
AP Home - static IP, no WEP key
AP Work - dhcp + WEP key
AP Friend - static IP + WEP key + gateway + nameserver + routing
All possible with my ebuild - linked in my .sig
