That's right, it's only executed on compute nodes.

That's strange, my slurm.conf man page from a system still running 21.08 
says:

UNKILLABLE STEP PROGRAM SCRIPT
        This program can be used to take special actions to clean up
        the unkillable processes and/or notify system administrators.
        The program will be run as SlurmdUser (usually "root") on
        the compute node where UnkillableStepTimeout was triggered.

Ah, I see, there's a later "FILE AND DIRECTORY PERMISSIONS" part which 
has the text that you've found - that part's wrong! :-)

All the best,
Chris
