/etc/resolv.conf and your ISP

I can think of a few ways to resolve this, but I thought to ask here.

I have Comcast for my ISP, and of course DHCP changes /etc/resolv.conf
during each update -- lately, they've been screwing things up bigtime,
such that I simply use my own "named" instance.

My question is:  how to reliably keep your own nameserver in
/etc/resolv.conf, and get around the frequent protocol updates that
change/nullify your mods to /etc/resolv.conf.

Perhaps just a regular script that does a diff and patch of it, or
simply copies over the file you want regularly.  Not elegant but it
would work.

I also wonder about creating a dhclient-exit script that would update
certain services automatically when your IP changes.


Thx.
