pxeboot/autoinstall and IPv6?

[fvgit]

We don't currently have IPv6-support for pxeboot(8) in OpenBSD, do we? I'm curious if an entirely IPv6-based autoinstall would be possible.

Both tftpd(8) and httpd(8) support v6 and a v6-capable dhcpd could be installed from the ports collection: net/dnsmask or net/wide-dhcpv6
The install.sub script on bsd.rd on the other hand seems to rely on dhclient(8), which is v4-only, I think. Something would be needed to provision the location of the response file over IPv6. Has anyone experimented in this direction, perhaps by hacking install.sub or sth. like that?

To my knowledge, there hasn't been a push for this because a) in practice OpenBSD network boots are conducted on LANs where IPv4 addressing is available, and b) there is no built-in DHCPv6 client in the OS. (SLAAC is included, but is not part of RFC 5970.)

I seem to recall the Project previously rejecting the inclusion of an in-base DHCPv6 client.
