has to be own by "nobody" and that user has to be able to access it (+x)
and write to it (+w) so that it can create a directory hierarchy showing
your clusters/nodes/metrics.

remember that to be able to access a directory you have to also be able
to access all other directories from starting from "/" and that will
basically require that the home directory for "developer" be publicly
accessible in most cases.

if you want to run gmetad as user "developer" then you have to start
gmetad as that used and disable setuid in /etc/ganglia/gmetad.conf :

  setuid off
