# Script for automated cloning and renaming of Fuss 9 client computers

# using mac-address as unique identifier.

# Donato Florio 11 April 2019

#

# Last modified 02 May 2019 --> added modification to support cloning on nvme* devices (HP G450)

# Last modified 07 May 2019 --> added various stuff for experimental autojoin to a domain

# Last modified 21 June 2019 --> added various stuff for experimental join to a cluster

# Last modified 01 July 2019 --> added ssh to script and changed disk detection method
