> If a SSVM in the zone is not available, meaning either it does not exist or
> the host entry is not Up or Connecting, DownloadCommand will get routed to
> LocalHostEndpoint. This is particularily dangerous in a NFS setup. If the
> mgmt server handles the DownloadCommand it has sudo access to mount NFS and
> perform the action. This mean the mgmt server is now in the data path, or
> worse, it could hang if it does not have network access to the NFS server.
