Yes, that would be the reason.

The first instance is specific to eth0 and the second is for all interfaces.
If they started the other way around this would not be a problem, but as eth0 
started first it is.

You'll need to fix that without my help :/

And yes, if you had resolvconf installed this issue would be mitagted, but would 
only hide other issues as the various dhcpcd instances would be competing to
process RENEW messages.

Maybe I should see if I can add code to stop dhcpcd running in master mode if it 
can detect any single interface running already.
