Description

As discussed via email with @demartinofra and Austin; I'd like to create a cluster with X86 and ARM compute nodes.
In my case with a x86 headnode.

AFAIU this is currently not possible since the headnode exports `/opt/slurm` to all compute nodes.

```bash
$ sudo exportfs|grep slurm
/opt/slurm 10.0.0.0/16
```

Thus, the compute nodes use the x86 binaries under `/opt/slurm/bin` and will segfault on any slurm commands.

Research direction

Start by examining how /opt/slurm is exported from the head node and how compute nodes use /opt/slurm/bin. Investigate the cluster setup paths that assume one CPU architecture. Done means a cluster with an x86 head node and both x86 and ARM compute nodes can run Slurm commands without architecture-related failures.
