Perhaps it would be wise to open #Ubuntu-LTS?

[Jo-Erlend Schinstad]

I've never proposed that we should create one channel per release. LTS
is special in that it's supported for a much longer time period. I'm
on Lucid, but I have no problems helping out with Karmic, or even
Jaunty. Ask me about Hardy, though, and I won't have much to tell you.

The difference between six months and three years, is significant.
