[Oneiric topic] IPv6

I have been having one-on-one conversation in the past few weeks with a
number of people around the question of IPv6 in Ubuntu. With the
upcoming IPv4 armageddon, I think it is quite pressing that we make sure
that we have good end-to-end IPv6 support in Ubuntu. I've been asked to
kickstart a discussion about it, and eventually distil the results in a
blueprint for the next UDS.
So, here are my notes on the stuff that would need to be investigated:
- Installer support: some work has been done upstream in netcfg and
d-i. Not sure about the status. I do not think Ubiquity has any
IPv6 support (or does it?)
- NFS: I was never able to make that work in Ubuntu. Reportedly, it
requires nfs-utils 1.2.3, which just got uploaded to Debian. I also
believe nfs-utils needs to be built with --enable-ipv6.
- DHCPv6: I understand we are getting that in Natty with isc-dhcp v4. I
know SLAAC is the way to go in most case, but some people wants/needs
DHCPv6 for various reasons. I guess it mostly needs testing.
- NetworkManager: It used to be that NetworkManager insisted upon
getting an IPv4 address, but Matt Trudel just marked bug #307598 as
fixed two weeks ago. Presumably, NM now work fine in IPv6-only network,
but I have not tested yet.
Any other major roadblock beside the above? I am going to sift through
the bugs tagged ipv6 on Launchpad, but if there's anything obvious I
missed, please let me know.
Finally, a question to consider is whether we want to address the
IPv6-only use-case (ie, not dual-stack, no IPv4 configuration). This
has some implications, notably around d-i and NetworkManager. Few
networks are IPv6-only at this time, but it's bound to change in the
Thanks for your insights.
