Templates should be immutable.
Additionally - the sysadmin side of me doesn't understand why I'd want
to do this at all. The template exists to get me to JEOS running - not
to manage updates. I (should) have tools that handle keeping all of my
deployed VMs in a consistent state, and updated to the proper version.
Trying to turn CloudStack into a patch management/package management
service seems a bit too much scope creep IMO.
