I have never noticed that this is true. I will have to look into your
statement.
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.
Do you access the Internet directly at home or through some sort of
router? If the latter, you can probably configure your home router to
provide DHCP service (including nameserver info) to your laptop.
I do this, and NM works just fine. I actually use a Linux box as a home
server. It runs dhcpd so it can even match IP addresses to MAC addresses
so machines get "static" addresses.
IIRC, NM should respect a static id set in /etc/sysconfig/network-scripts,
but you still need to stop it and change profiles if you sometimes have a
static id and sometimes want to DHCP.
