If you have a network profile that is based upon a fixed IP address and 
DNS servers (which I do have at home behind a router with DHCP 
disabled), then NM will overwrite the configurations for that profile, 
including /etc/resolv.conf.

I use NM at work, where we have DHCP and of course with wireless 
networks when travelling.

However, at home, I end up disabling NM and then run a shell script 
which activates the Home profile and associated config settings and then 
ifup's eth0.

It seems to me that I have seen references to this previously, relative 
to using NM when one has a fixed IP and DNS settings. My recollection is 
that NM is really configured for DHCP based nets and does not (yet) 
support network profiles.

However, I would love for somebody to tell me that I am wrong on this, 
as I would love to not have to go through the steps that I do when at home.

HTH,
