[Bug 1240972] Re: [SRU] maas dhcp.conf template not adding ignore-client-uids unless using raring or later

[Andres Rodriguez]

** Summary changed:

- maas dhcp.conf template not adding ignore-client-uids unless using raring or later
+ [SRU] maas dhcp.conf template not adding ignore-client-uids unless using raring or later

** Description changed:

  1. Description of the problem:
  
  The maas dhcpd.conf.template only adds ignore-client-uids if using
  raring or later. Packages in the cloud-tools archive should work on
  precise and require this option for dhcpd. I have verified that dhcpd
  starts after adding ignore-client-uids
  
  root at maas1000:~# cat /etc/maas/templates/dhcp/dhcpd.conf.template
  ...
  subnet {{subnet}} netmask {{subnet_mask}} {
-        filename "{{bootloader}}";
-        {{if platform_codename >= 'raring'}}
-        ignore-client-uids true;
-        {{endif}}
-        option subnet-mask {{subnet_mask}};
+        filename "{{bootloader}}";
+        {{if platform_codename >= 'raring'}}
+        ignore-client-uids true;
+        {{endif}}
+        option subnet-mask {{subnet_mask}};

+ 
+ [Impact]
+ No having the option enabled by default causes DNS/DHCP to misbehave when managed by MAAS. This option needs to be added when installing from CA/ cloud-pocket tools, however, in order for it to hit the CA needs to be SRu'd.
+ 
+ [Test Case]
+ 1. Install maas
+ 2. check that /etc/maas/templates/dhcp/dhcpd.conf.template has the option enabled.
+ 
+ [Regression Potential]
+ Minimal. This won't affect saucy at all, but it is required for the cloud-archive (which uses the latest from saucy).
