DNSDOMAIN in /etc/conf.d/domainname has no effect? (was: [gentoo-user] hostname -d returns no domainname)

I seem to remember that this was somehow related to /etc/hosts, look:

# cat /etc/hosts


Changing:


10.0.0.10  mybox   mybox.my.domain


to:


10.0.0.10  mybox.my.domain   mybox


has just solved this issue for me. :) Thanks!


Same here!

But I wonder what this DNSDOMAIN setting in /etc/conf.d/domainname is
supposed to do. Because of

# When setting up resolv.conf, what should take precedence?
# If you wish to always override DHCP/whatever, set this to 1.
OVERRIDE=1

I thought that this setting would have an effect. Seems not so...

Here is why this solved the issue for you.  hostname -d and hostname --fqdn 
get the domain part by using gethostbyname() so it does a DNS lookup on your 
hostname.  If your /etc/hosts.conf is set to files, bind then it will look 
your hostname up in /etc/hosts then query DNS.  If your /etc/hosts file has 
an FQDN entry for your hostname then all is well.  If not then your hostname 
is queried in DNS using the domain statement in /etc/resolv.conf.

 But I wonder what this DNSDOMAIN setting in /etc/conf.d/domainname is
 supposed to do. Because of
It sets the domain in /etc/resolv.conf

 # When setting up resolv.conf, what should take precedence?
 # If you wish to always override DHCP/whatever, set this to 1.
 OVERRIDE=1

This will determin whether DHCP will be allowed to replace your domain 
statement in /etc/resolv.conf.

I hope this clears it up.
