Good clue (though I've been there)
Works for wired but not wireless. Environmental variables are set for
wired configs - eg "DHCP4_IP_ADDRESS" but don't exist when the same
simple script is called via a Wireless interface coming up.
I do see the info in '/var/log/messages' but I think at a later stage of
the whole process.
I was also hoping that as I saw in my /var/log/messages files references
to Router Advertisements, that my IPv6 addresses might also be available
in the shell environment - but alas....
(not running DHCPv6 daemon on my network yet?)

Also, any clues to building a custom resolv.conf (half from DHCP, half
static)?
