 YES! it does register, hurray.

 Do **NOT** mount ''/opt/intel'' and ''/opt/ohpc/pub'' from SMS, that's all Rocky8.5 stuff.

-Just a mental note. There is a warning on Slurm web page re the older versions archives page

-Due to a security vulnerability (CVE-2022-29500), all versions of Slurm prior to 21.08.8 or 20.11.9 are no longer available for download...so why is openhpc v2.4 running such an old slurm version?

+Third Idea: once we're fully deployed I may go to latest Slurm version, run on different ports with maybe newer munge version (although that should not matter, why does this scheduler even need munge?)
+Run Slurm outside of openhpc via local compile in ''/usr/local/''. A standalone version, the most recent version.
-Once we're fully deployed I may go to latest Slurm version, run on different ports with maybe newer munge version (although that should not matter, why does this scheduler even need munge?) and run Slurm outside of openhpc. A standalone version.
+Decided to go this route v22.05.02 standalone version (with ohpc v1.3 or v2.4 munge packages). You need all three packages (munge, munge-libs and munge-devel) on host where you compile slurm (note: cottontail2 for rocky8.5, node n90 for centos7). Then just copy.
