Comment 5 for bug 991347

About the last comment: I do not understand very well what's going on. Here's what I did:

* Before looking at these comments, I removed all wired connections from network manager configuration. I rebooted the server and the resulting resolv.conf was not referencing 127.0.0.1 anymore, but the DNS servers from dhcp directly; I re-added a wired connection from the main adapter (eth0) with DHCP and the same stuff happened.

* After that I noticed that the dnsmasq package wasn't installed. I forgot to add the line from ps -ef that showed that dnsmasq was running as a child process from NetworkManager (I even remember the --no-hosts parameter) even without the dnsmasq package being there

* I installed dnsmasq just to see what would happen, and the resolv.conf referencing 127.0.0.1 became active again, and again, it does not work if I configure my DHCP server to lend it many servers. However, if I tested with one DNS server and four DNS servers, and both worked OK.

* This "new" dnsmasq process is not a child from NetworkManager and does not have the file /var/run/nm-dns-dnsmasq.conf - what is going on, does Networkmanager has a different dnsmasq that comes with it?

* As you can see, before this day I only had dnsmasq-base and not dnsmasq installed:

* I have a central server on my intranet that also does DNS resolution and caching. Is dnsmasq really needed on this scenario?
