A sub item to this (sure it's known already but will toss it in again to be sure)

Under new procd of OpenWRT (Barrier Breaker and newer) a restart call to a procd type init.d script is suppose to be somewhat
safe (for the service uptime) in that procd should not restart the service unless the (generated) config files have actually changed. 

This is useful for olsrd and other programs as one can just call a service restart any time an action could affect the service (hotplug) but unless the event actually did affect the service config it won't do anything.
