1. First of all, create the playbook for generating the preseed files locally.

          - preseed

			




	
	
	
		
 

			




	
	
	
		
 
2. And that's about it... Now we can generate the pressed files::

			




	
	
	
		
 
2. Configure the role by creating the configuration file:

      # Directory where the preseed files will be output to.

			




	
	
	
		
 
      preseed_directory: "~/mysite/preseed_files/"

     workon mysite && ansible-playbook playbooks/preseed.yml

5. You can have a look at them, but you might notice the settings in the file

			




	
	
	
		
 
   might not be to your liking. In particular, it could be using wrong timezone,

			




	
	
	
		
 
   defaulting to DHCP for network configuration etc. Let's concentrate on making

			




	
	
	
		
 
   the network configuration changes - this is the main thing that will probably

			




	
	
	
		
 
   differ in your environment. Create a new configuration file:

servers ``comms.example.com``, ``www.example.com``, and

			




	
	
	
		
 
``bak.example.com`` using them with network install CD. Have a look at
