dhcpcd-discuss

Top posting as a quick response. I twerked the config (deleted the ra-own stuff, dropped the 1-year lease time, dropped the nohook, dropped the iaids for eth0-3], changed the eth3 iaid to '1', and changed the requested addr to ::/60. Results: it didn't actually add the addresses to eth[02], but did to eth3. It's better.

I think I specified the iaids in order to 'force' them to known values. (I generally abhor computer-generated IDs; they're so abstract that only a computer can relate them to 'reality'.)

Still get the autolink error; this is on the same kernel (3.4.109) that was OK before; oh, but I built for 3.16.49 which refuses to boot properly on my hardware, so yes, likely kernel headers. Should it be OK to run programs build with newer headers on an older kernel?

I will try HEAD tonight and test more thoroughly. And send more detailed logs.
