To support this, we have a\nseparate systemd unit called `xrootd-privileged@.service`.\n\nTo start the configuration in `/etc/xrootd/xrootd-clustered.cfg` with the multiuser plugin enabled, execute:\n\n```\nsystemctl start xrootd-privileged@clustered\n```\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fopensciencegrid%2Fxrootd-multiuser","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fopensciencegrid%2Fxrootd-multiuser","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fopensciencegrid%2Fxrootd-multiuser/lists"}
