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:
on a Linux Service Node
if site.installloc set
mounts /install
if site.installloc not set
creates /install if needed
sets up nfs
exports /install
#-------------------------------------------------------
=head3 handled_commands
If bypassmode then exit
If xcat daemon reload then exit
Check to see if on a Service Node
If Linux
Call setupInstallloc
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
