=head1  AAsn

 This is the Service Node Plugin, although it does perform a few functions on
 the Management Node.   
 It reads the servicenode table for the service node it is running on,
 and run the appropriate
 setup routine for each service that is designated to be setup in the 
 servicenode table for this service node. Some functions are only done for 
 Linux.
 A few functions are done not based on the servicenode table. For example:

  mounts /install if site.installloc set
  on a Linux Service Node

#-------------------------------------------------------

=head3  handled_commands

If bypassmode then exit
If xcat daemon reload then exit

Check to see if on a Service Node
If Linux
   Call  mountInstall
If this is a service Node
  Read Service Node Table
   For each service returned to be setup
	  Call the appropriate setup_service routine
else if on the Management Node
  Do any Management Node setup of services needed
