All config is in one place. IP address, default gateway, domain
name, DNS servers, search path, the lot.

The mix of having to do this crazy thing of gateway announcements
from one place, DNS from somewhere else, possibly auto-assigning
addresses from a router, but maybe getting them over DHCPv6. It's
just confusing and unnecessary and IMHO isn't helpful for
persuading people to move to IPv6. Especially when everyone
already understands DHCP in the v4 world.

Both RAs and DHCP have their place and can be really useful
together or apart in different situations, but witholding key
functionality from DHCP "beacuse you can do it in a RA instead"
isn't helping the v6 cause.
