+#   This script is provided as sample reference only, for installing         #
+#     pre-requisites for Graphistry Enterprise Server on an "RHEL 9"         #
+#     base image. The process follows loosely the steps                      #
+#     taken when we build the underlying base AMIs.                          #
+#                                                                            #
+#   The script may reboot the machine once, and will need to be run          #
+#    a second time to finish the installation.                               # 
+#                                                                            #
