Re: An equivalent to dhclient.conf's "prepend domain-name-servers"?

[Carl Baldwin <carl ecbaldwin net>]

Hehe, that is very similar to what I've been doing.  See the link
below, I wrote the post about the script, run from cron, that edits
the resolv.conf file with ed.  I didn't bother with file monitoring
because I wrote it quick and dirty.

I'm really looking for NetworkManager to provide the ultimate solution
so that I can stop having to put so much thought in to this each time
I've got a new machine to set up.

Even if NetworkManager just provided a boolean option to support a
local caching nameserver.  This could be presented in the GUI as "This
system has a caching name server" with a check box.  Default is off.
I would like a way to configure this from the command line but I'm
sure I could figure that out by learning a little more about dbus.

You know what!  I just found in the NetworkManager release notes
(wiki, ReleaseProcess) that "Local caching nameserver support" is
tentatively planned for the 0.8.2 release.  I missed this before.
This is great!  You have my vote for this feature!

Thanks,
Carl
