Good idea. I've added this, with a slight tweak (I used NOTUPGRADABLE=true for 
consistency with the negative-sense of the NotUpgradable xenstore key, and 
dropped the "e" for uniformity). The relevant text now reads:

configuration file

/etc/xe-guest-utilities.conf

which has default contents:

        #Uncomment in appliance VM

        #NOTUPGRADABLE=true

If the file is modified so that NOTUPGRADABLE is defined as "true" then the 
NotUpgradable key will be automatically added to xenstore. The linux guest 
agent will still continue to write the existing version number keys.
