Whenever you see an completely unqualified version number or just some  
random cutesy name it is generally safe to assume this refers to a  
version of Ubuntu.  It is just the self-involved nature of the Ubuntu  
community.

Their wiki <https://help.ubuntu.com/community/NetworkManager> for  
NetworkManager doesn't have current information on how they  
package/configure NM.

(I'd think this is a reasonable NM feature request).

NetworkManager uses dhclient in most cases, so perhaps look at  
"/sbin/dhclient-script".  It looks like it reads the settings via  
netconfig.  Perhaps a static or additional DNS search scope could also  
be enforced that way.

netconfig
---------------------
On openSUSE [and possibly other distros] you can modify  
/etc/sysconfig/network/config which supports the following directives:
NETCONFIG_DNS_STATIC_SEARCHLIST
NETCONFIG_DNS_STATIC_SERVERS
NETCONFIG_DNS_FORWARDER

These are applied by netconfig when generating /etc/resolv.conf from  
/etc/resolv.conf.netconfig.   Note that these only count when  
NETWORKMANAGER="no", otherwise it is all up to NetworkManager
