Code review comment for lp:~rvb/maas/fix-etc-hosts-bug-1087183-2

https://bugs.launchpad.net/maas/+bug/1378479 has all the latest. I reproduced it on a brand new maas installation first by installing an older version and confirming maas works. Then I upgraded to the version in the testing ppa and it broke. I believe it's not related to the change in this MP, you just happen to have branched off a trunk version that had the problem already. But until that is fixed, I can't verify it for you.
