Hi James, Slurm 19.05.5 face the same problem with Centos8, so hardened environment, and the same fix helps. I will test slurm 20.02 as soon as possible.

I can confirm that 'fixes' it. slurmd now starts, the node joins the cluster, I can at least get an interactive session on it (haven't tried anything else). In case that's of interest - this is actually SLURM 18.08.3 that I've now gotten to run (I haven't quite managed to upgrade to 19 yet). I've made minor modifications to the spec file - the unhardening of the flags and the the python dependency.
