Request for Classic confinement: Slurm

[jdstrand]

@egeeirl

There are common scenarios when an operator wishes to run a Slurm command as another user, oftentimes for accounting purposes. A simple command that will invoke the issue:

slurm.srun --uid 1000 -N1 -l uname -r

The command above tries to run as UID 1000 but cannot because of the confinement mode. As such, it leads me to this request.

What are representative use cases where the user might specify --uid (eg, especially but not limited to “accounting purposes”)? If it is just to run something as non-root, we have system-usernames that would allow someone to run slurm.srun --uid 584788 -N1 -l uname -r.
