Thanks for bringing this up. This also includes the question for how
long we should support updates in general. (I'll open a new thread
instead of hijacking this one)
For the minimum kernel requiring the oldest lts one seems sane to me.
This should ensure a smooth update even if you use our lts kernel and
don't update that often.
3.6.18 was released for years ago, so I don't think a lot of Arch users
would be affected.
