  36 # Handling a corner case here. If we were in offline state due to an
  37 # unsatisfied dependency, the ipf_method process wouldn't have generated
  38 # the ipfilter configuration. When we transition to online because the
  39 # dependency is satisfied, the start method will have to generate the
  40 # ipfilter configuration. To avoid all possible deadlock scenarios,
  41 # we restart ipfilter which will regenerate the ipfilter configuration
  42 # for the entire system.
  43 #
  44 # The ipf_method process signals that it didn't generate ipf rules by
  45 # removing the service's ipf file. Thus we only restart network/ipfilter
  46 # when the file is missing.
