Interface : PBS_LEAF_NAME would accept multiple comma separated values. 

  1. Visibility: Public
  2. Change Control: stable
  3. Synopsis: Introducing new functionality for PBS_LEAF_NAME configuration variable. 

Earlier PBS_LEAF_NAME would accept only one value. If a value was provided it would resolve that name and find the ip address associated with that name. It would then report the ip addresses to the comm. However, the problem with that was that if the name was not mapped to all the interfaces in the host (say at /etc/hosts or DNS) then those interface/ips were not registered.
Now, we can specify multiple names (comma separated) to the variable PBS_LEAF_NAME.
If this variable is not set, then we detect all the ip addresses of the machine and all these IP’s are registered with the pbs_comm

We will consider only the first value of  PBS_LEAF_NAME as a host name for the sake of daemons starting/stopping etc.
