You should probably not issue any config map updates except the very 
first one. The reason being that each config map is considered a 
"package checkpoint" where these specific versions of the packages have 
to be present in the image before the updater continues.

This is critical if we have brutal changes like the closure stuff, but 
is only confusing when it comes to a package like VMMaker that almost 
never has life instances to worry about. The updater *always* updates 
the last configuration found to the latest package version in the 
repository so a single MCM can be used for a long time until you either 
add a package, or remove a package, or need a package checkpoint.
