#   This script is called in the following different places:

#      updatenode -S --> xcatdsklspost 2 -m/-M otherpkgs
#      moncfg rmcmon --> xcatdsklspost 3 configrmcnodes

#      statelite mode   --> xcatdsklspost 4
#      update security  --> xcatdsklspost 5 -m/-M ...
#      node reboot - xcatpostinit1  --> xcatdsklspost 6
