There should be DNS scripts in the contextualization packages that provide some 
assignment of DNS. You should be able to slightly modify a script to pick up 
that variable you define, i.e. 

echo search $searchdomain >> /etc/resolv.conf 

And define the $searchdomain variable in your network template. 


Be advised, I only see this script on the Ubuntu context packages (not 
RHEL/Cent, but could be added either way)

Subject: [one-users] DNS search domains and rc.local not being read in VMs 



Hello, 



I posted a few days ago about network configuration seemingly not being picked 
up properly – I think that was mainly due to my contextualisation packages 
being for the wrong version, and so the context CDROM device wasn’t being 
mounted. 



So now I have a separate,, but related issue. 



I need to be able to have DNS search domains in my /etc/resolv.conf. I tried to 
achieve this by adding a SEARCH attribute to the virtual network template, but 
it doesn’t seem to be picked up (looking in the context scripts, there’s 
nothing there to pick it up, so that’s kind of expected). I then tried to add 
it in /etc/rc.local, along with some lines to correctly set the hostname based 
on IP, but this doesn’t appear to be being picked up either. 



Could anyone tell me what might be going wrong here? Could it be the case that 
rc.local is not being run for some reason at boot? When I test the VM outside 
ONE, rc.local runs fine… 



Any help greatly appreciated. 



Thanks
