/etc/slurm/slurm.conf is a symlink to /home/conf/slurm.conf, and /home 
is NFS-mounted on every node. No need to re-distribute it :)

Given the type of changes, I opted for "systemd restart slurmctld" (and 
restart slurmd on the worker nodes). cssh and bash-completion make it 
quite fast :)

Eager to see it in Debian :)

but I'm not really OK with it yet (for example I still can't understand 
how I can exclude some metrics from a host that got 'em added by a 
template... When I'll have enough time I'll find a way :) ). Maybe 
pestat can be added to the Zabbix metrics...
