The discussion in bug 15632 concludes that this bug will only be fixed in 
23.11.  Your workaround looks nice, however, I have not been able to find 
any documentation of slurmctld calling any Lua functions named 
slurm_cli_pre_submit or slurm_cli_post_submit.

Some very similar functions are documented in 
https://slurm.schedmd.com/cli_filter_plugins.html for functions 
cli_filter_p_setup_defaults, cli_filter_p_pre_submit, and 
cli_filter_p_post_submit.

Can anyone she light on the relationship between Tommi's 
slurm_cli_pre_submit function and the ones defined in the 
cli_filter_plugins page?

Thanks,
Ole
