# When it's time to run the next upgrade, change the value for
# package_name to the appropriate version.

# hieradata version
node coors {
  include profiles::tomcat
}
node beck {
  include profiles::tomcat

# In the hieradata file for common.yaml

profiles::tomcat::package_name: 'tomcat6'

# In the hieradata file for coors.yaml

profiles::tomcat::package_name: 'tomcat6'
# EOF

# In the hieradata file for becks.yaml

#EOF

# When the time comes, update the appropriate heiradata files


# Final alternative, create a factor method that returns the desired package version
#... to be determined

# Once in place, you should be able to reference it as a fact
