    Yes, but how do you make sure the option is set when the agent is active?
    I think relying on a kernel boot option here is quite fragile.
    Also it's something the administrator shouldn't be involved in.

    We can just define one. We had Linux specific extensions before.
    Just needs a new bit somewhere. I think that would give a better
    experience for your customers.

    There might be something forthcomming that could be usable in fact.

    The bug fixes should go in 2.6.30. After all that is what the rc stage
    is for -- applying bug fixed.

    Not yet sorry.
