• Brief description of the issue
  In file 05_start_required_daemons.sh, rpcinfo is used with option "-p localhost". This will require specific configuration to be in place and can fail.

For example, on one of my systems this produces the message:
rpcinfo: can't contact portmapper: RPC: Authentication error; why = Client credential too weak

If rpcinfo is used without any option, it will default to localhost anyway (at least on RHEL), which works fine on all of my hosts.

Suggested change:
Change "rpcinfo -p localhost" to "rpcinfo" in the complete file.
