   6 # rebooted. This one calls an URL given as a boot parameter e.g.
   7 # local_boot_trigger=http://cobbler.server.example.com/cblr/svc/op/nopxe/system/@HOSTNAME@

   9 # In this example, Cobbler is triggered to change pxelinux config for that
  10 # system to perform a local boot when /etc/cobbler/settings/pxe_just_once
  11 # is set to 1.
