We have

  $ ll -d /etc/slurm
  lrwxrwxrwx 1 root root 25 Feb  4  2019 /etc/slurm -> /trinity/shared/etc/slurm
 
and this works for us.  Are you also using a link or actually trying to
specify the NSF folder itself somewhere?

BTW, I think this kind of setup has been made obsolete by "Configless" Slurm:
