Run a script when no DHCP server available

I will be taking a gentoo system to mutiple locations some have a DHCP server some do not. When I have the system at a location with no DHCP server I want a script to run that sets some network settings, How can I do this?

The _wrong_ way to do this is to edit /etc/init.d/net.eth0 and put an extra line in after line 39 (in the standard file), the line that says: 'eend ${retval} "Failed to bring ${IFACE} up" '.

Just run your script at that point.

It's ugly, but should work. I'll be watching out for the better way...

So I shouldn't add to it /usr/sbin/iwconfig "eth0 mode ad-hoc"
and the rest of the script lines then because that is the dirty way to do it and not propper way. Right?

I haven't checked it yet, but you can do this without editing the /etc/init.d/net.ethX script, but by changing the dhcpcd_ethX variable in /etc/conf.d:

I just received word that this won't work. However, there has already been a bugreport (with solution) for this:
