 Well I don't know what is "accurate" behavior.
 
 There are two points:
 
 - As noted in the PR, replacing /libexec/dhcpcd-hooks/30-hostname
   with 29-lookup-hostname and 30-hostname from NetBSD 6.1.5 makes
   dhcpcd(8) use "expected" hostname even in sysinst.
   dhclient(8) in NetBSD 8.1 also uses an expected hostname.
   (I'm not sure if it's provided from dhcpd or not)
 
 - The default name of "localhost" is annoying for me because
   it's also used by sysinst as default settings in /etc/hosts.
   Blank is still better for me.
 
 Is there any intentional changes (lookup removal?) from 6.1.5 one?
