dhcpcd 10.0.2 vs. 10.0.4 (was: vnic_eth_plugin incompatible with dhcpcd?)

It appears that the vnic_eth_plugin, which has been enabled by default in the alpine AWS package, is incompatible with dhcpcd, which is wha the 3.18+ Alpine images are using for managing DHCP leases.

While a newly launched instance does successfully get an IP, it is unable to keep it beyond the lease. dhcpcd itself is not running.
