    Subjectkernel upgrade on the fly
    Hi all,

    has anybody worked or thought about a property to upgrade the kernel
    while the system is running? ie. with all processes waiting in their
    queues while the resident-older kernel gets replaced by a newer one.

    I can see the advantage of such a thing when a server can have the kernel
    upgraded (major or minor upgrade) without disrupting the ongoing services
    (ok, maybe a small few-seconds delay). Another instance would be to
    switch between different kernels in the /boot/ directory (for testing
    purposes, etc.) without rebooting the machine.

    A search of the web resulted in no related information to the above so I
    dont know if such an issue has been raised before.

    Would anybody else think this to be an interesting property to have for
    the linux kernel or care to comment on this idea?

    Cheers,
