The preStart snippets (graphite, carbon) try to create directories under /var/db/. That currently fails because the code is run as user "graphite". Fix by setting "PermissionsStartOnly = true" so that the preStart stuff is run as 'root'. Further: * graphite-web-0.9.12/bin/build-index.sh needs perl, so add it to PATH. * Now that preStart runs as root, we must wait with "chown graphite" until we're done creating files/directories. * Drop needless check for root (uid 0) before running chown.
