This option should be used when -z|--clonezilla-mode = 3"

This option is for the DRBL client is NFS based, i.e. all files are NFS mounted from server. It's different from the option '-u', which is only for clonezilla mode."

  echo "-x, --limit-pxe-drbl-client  Force the DHCP service managed by DRBL will only allow PXE or DRBL clients to lease IP address. By default all the clients can lease IP address. //NOTE// If you want to use Clonezilla live as the OS of clients when running Clonezilla job, do _NOT_ use this option. Otherwise your client won't be able to mount the root file system."
