"Network Profile" for laptop users

Hi,

I wonder if it is some how possible to define a kind of a network profile for mobile use. I have a laptop that I use at home, at school and at work. I would like to have the runlevel changed (to a custom on) based on the ip (and other informations) that I get over dhcp. Or any other actions to be taken based upon this information.
When I am at work and get IP X with default gateway Y then I would like gentoo to boot into the runlevel "work" and login (in gdm) with the user "work".

Is this total nonsense or somehow possible?

Thanks
Stefan

That's possible, sure. One way would go like this:
Emerge ifplugd and configure it to execute a script (-r parameter in ifplugd, I think) that calls a different runlevel based on the IP.

The _automatic_ booting into a special runlevel is a thing I haven't solved well yet. Of course you can boot with a softlevel=xy parameter, but I'd like a more automatic way. I don't know if it is possible without modifying /sbin/rc. Calling another runlevel after default is easy though.

You could write a script that detects whatever setting you want to trigger off of then calls the runlevel. Then call that script from /etc/conf.d/local.start. It gets run after (I think) all the other services in the default runlevel.

I wrote a script like this that greps dmesg to detect if my USB NIC is present and starts a runlevel that brings up networking and the desired services on top of that. I don't know that it's the most graceful solution imaginable, but it works fine.
