In short:

On the login node, just install slurm and munge with the same config
files as on the other nodes, but don't list it in the node
configuration.  Then the slurm commands (squeue, sbatch, etc.) will work
on the login node so you can submit jobs, but no jobs will be run there,
and no daemons will run there.
