Details - I have noticed that some services reloaded with a procd "interface.*" raw trigger are reloading on a much more frequent cadence (few minutes or so). LEDE 17.01 does not do this. LEDE Trunk does. I can not find an obvious cause in procd. Though procd should not stop-start for reload without a command line change or explicit file under watch. Perhaps netifd commit a03216660797173fbe67866f75564e3fec9c1e8d is generating unusual numbers of IFUP.
