 I don't understand this. For the typical client with DHCP and IPv6
 autoconfiguration, you need one setting only: dhcpcd=YES. If you want
 static IPv4 and IPv6 autoconfiguration, there are three options:
 (1) Setting -6 for dhcpcd and "classic" ipv4 configuration
 (2) Setting ipv6only in dhcpcd.conf and "classic" ipv4 configuration
 (3) Using dhcpcd.conf for all address configuration
 
 All three options cover different use cases. So yes, autohost is broken,
 but the alternatives are no more difficult.
