I am one of the Gentoo users who supports the many hapless souls in #gentoo on freenode. I have to help ~ 5 people a day who have no dns resolution due to setting dns_domain_lo="some_domain" in /etc/conf.d/net . It is not specified in the Handbook that if they set this /etc/resolv.conf will get overwritten, and the DNS servers handed out by their DHCP server will be overwritten as a result. There needs to be a clarification in the handbook on the consequences of setting this directive. Section to which I am refering: 8.b. Networking Information Code Listing 5: Setting the domainname & Code Listing 6: Setting the NIS domainname
On the other hand if you install resolvconf-gentoo then it will manage resolv.conf for you and merge all settings. I've updated baselayout documentation for this in net.example in our svn - will be in the next release. Maybe the docs team could include that in the handbook too?

No, we don't say that baselayout will screw your resolv.conf, but on the other hand, throughout that whole chapter, we constantly provide warning after warning about reading conf.d/net.example to read how to properly use DNS and other similar settings -- the example file is the appropriate place to learn about such advanced topics (and it deals more with proper DNS configuration). I will, however, add a note about emerging resolvconf-gentoo to the networked handbook.

Also many people do not understand networking all that well. And from the handbook, that section seems to say you need to set that dns_domain_lo ...
Added a note about emerging resolvconf-gentoo to assist with DNS/NIS management. Uberlord, any chance of getting this helpful note into the current stable baselayout, so that users installing 2006.1 will get the helpful message in conf.d/net.example right away? It wouldn't be too much of a problem to "backport" the note, would it? :) Fixed in CVS on the GDP end.
At certain points you refer to /etc/conf.d/net.example, which doesn't exist. It isn't helpful to refer to an example file not found at the place mentioned ...
This is marked resolved/fixed. After installing gentoo from scratch I'd say: it is not. Not even in the latest snapshot available!
