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