   In bash, this would be fairly simple:

   # new host to use
   NEW_HOSTNAME="staging.mysite.com"
   # grab old host to replace
   OLD_HOSTNAME=$(hostname)
   # hostname change to apply before restart
   sudo hostname $NEW_HOSTNAME
   # hostname change to apply after restart
   echo $NEW_HOSTNAME | sudo tee /etc/hostname
   # replace any uses of old in /etc/hosts
   sudo sed -i "s/${OLD_HOSTNAME}/${NEW_HOSTNAME}/g" /etc/hosts

   Should translate easily enough to ansible...?

   Looking into this, and maybe a stupid question: I know we have a ${domain} global var available in the ansible tasks...do we have any way to see what stage we're running under? (eg, to get the full hostname we're wanting to set)

   Good news: we can eventually replace much of whatever we do for this with ansible/ansible#3940

   Update: that PR was merged and looks like it will be part of ansible's next 1.4.* release
