Bug#954272: Missing mpi_pmix.so


After updating, the interface between SLURM and MPI broke again...

This time, it looks like pmix support is completely missing.

# strace srun ./a.out 2>&1 | grep pmix
stat("/usr/lib/x86_64-linux-gnu/slurm-wlm/mpi_pmix.so", 0x7ffe65c74160) = -1 ENOENT (No such file or directory)
write(2, "srun: error: Couldn't find the s"..., 87srun: error: Couldn't find the specified plugin name for mpi/pmix looking at all files
write(2, "srun: error: cannot find mpi plu"..., 49srun: error: cannot find mpi plugin for mpi/pmix
write(2, "srun: error: cannot create mpi c"..., 52srun: error: cannot create mpi context for mpi/pmix
write(2, "srun: error: invalid MPI type 'p"..., 70srun: error: invalid MPI type 'pmix', --mpi=list for acceptable types

It appears that SLURM is looking for `mpi_pmix.so`, which does not exist. Has this been moved to a different package maybe?
