But one possible way to something similar is to have a partition only
for interactive jobs and a different partition for batch jobs, and then
enforce that each job uses the right partition. In order to do this, I
think we can use the Lua contrib module (check the job_submit.lua
example).

Wouldn't it be simpler to just refuse too long interactive jobs in
job_submit.lua?

This sounds like a good idea, but how would one identify an interactive job in the job_submit.lua script? A solution was suggested in https://serverfault.com/questions/1090689/how-can-i-set-up-interactive-job-only-or-batch-job-only-partition-on-a-slurm-clu

Interactive jobs have no script and job_desc.script will be empty / not set.

So maybe something like this code snippet?

if job_desc.script == NIL then
   -- This is an interactive job
   -- make checks of job timelimit
   if job_desc.time_limit > 3600 then
     slurm.log_user("NOTICE: Interactive jobs are limited to 3600 seconds")
     -- ESLURM_INVALID_TIME_LIMIT in slurm_errno.h
     return 2051
   end
end
