[slurm-dev] On the need for slurm uid/gid consistency

[Phil K]

I'm hoping someone can provide an explanation as to why slurm requires uid/gid 
consistency across nodes, with emphasis on the need for the 'SlurmUser' to be 
uid/gid-consistent.   I know that slurmctld and slurmdbd can run as user 
`slurm` and that this would be safer than running as root.  slurmd must run as 
root in any case, to my knowledge.  Is the need for uid consistency, esp with 
the SlurmUser a difficult barrier to overcome?  Please clarify for me.  Thanks.
