This is due to newer versions of SLURM using /sys/fs/cgroup (as in RHEL7)
rather than /cgroup (as in RHEL6). It would have been a no-brainer to check
and do the right thing, but as it is, you have to specify the cgroup mount
point in cgroup.conf if you're on the wrong system for your slurm version.
slurmd could be a little more explicit with its error messages...
