 # DefaultDependencies takes care of sysinit.target,
 # basic.target, and shutdown.target
 
 # We need networking to bind to a network address. It is recommended not to
 # use Wants or Requires with network.target, and not to use
 # network-online.target for server daemons.
 After=network.target
 
 # Time syncs can make the clock jump backward, which messes with logging
 # and failure timestamps, so wait until it's done.
 After=time-sync.target
 
 # Some OCF resources may have dependencies that aren't managed by the cluster;
 # these must be started before Pacemaker and stopped after it. The
 # resource-agents package provides this target, which lets system adminstrators
 # add drop-ins for those dependencies.
