mpirun - no output to stderr/stdout if prrte launch_orted_on_hn is true #7399
Description
By default, the mpirun now in master following the orted removal no longer forwards stdout/stderr from MPI processes in a job if the PRRTE launch_orted_on_hn mca parameter is set to true.
Its not clear how to feed the get the mpirun/prun binary to do the equivalent of
prte --daemonize --system-server
prun -n 4 --system-server-first
from the mpirun command line. The help documents a system-server-first option but this doesn't seem to be applicable.
