[OpenIndiana-discuss] DNS server and domain from DHCP?

[Bill Sommerfeld]

Autoconfiguration of /etc/resolv.conf on illumos could really use some 
attention and modernization - besides the glitch you noticed, there is 
also currently no way to automatically use ipv6 nameserver addresses 
either from DHCPv6 or IPv6 stateless address autoconfig.

Funnelling the settings through SMF properties would absolutely make 
sense as any dual-stack config necessarily must merge config from 
multiple sources.
