#    TBD
# For Linux:
#    - For full-disk installs:
#        - Copy rpms to node
#        - Install and accept PE license rpm
#        - Install PE rpms
#    - For diskless images:
#        - Install PE license on MN if not already installed
#        - Install PE license rpm into image, but DO NOT ACCEPT
#          (java accept program will hang)
#        - Copy PE license files from MN into image
#        - Install PE rpms
#    - Create a smaller PNSD log file in /tmp 
#    - Configure poe.limits file
