so as discussed recently having the inet6 link-local addrs on every

Connecting a computer to the internet is a security risk.
IPv4 is on by default, and so IPv6 should be on by default.
I want both to be handled the same way.
WITH my diff they finally become the same, IPv4 does NOT assign some
special address to the interface by default.
The analogy really breaks here since v4 just doesn't have link local.
the only use case that needs config adoption: people ONLY using
link-local, they will need to put +inet6 in the corresponding
hostname.if file.
There is a use case for running IPv6 over an interface without
setting an address. Configure a global IPv6 address on lo0, run
ospf6d on any physical interface and it will provide connection.
IPv6 autoconfiguration with link-local addresses is useful.
so you put +inet6 in the corresponding hostname.if file and everything
works like you want it to.
While my powers in this field are limited, I would really hate to see
another operator "type" (e.g. +foo +bar) being introduced in ifconfig.
It's cludgy enough already IMO.
If we need +inet6, it's a pointer that "inet6" is already busy and we
should look something else.
eui64 sounds better so me.
