    >From experience, it generally installs *BOTH*. The information about which
    should be the default kernel is stored in /etfc/sysconfig/kernel, and is
    used to set the default kernel when you do kernel updates. I'm personally a
    big believer in ripping out kernels you don't use or plan to use, such as
    ripping out the single-processor kernel when you have an SMP machine, just
    to lighten the load on your disk and your RPM database and help avoid
    confusion when booting.

    Do note: if you're running a single CPU kernel, there is *no way* short of
    installing a LinuxBIOS (which I don't recommend for amateurs) to detect that
    you actually have another CPU or hyper-threading available, short of
    rebooting with an SMP kernel and looking around in /proc/cpuinfo or using a
    tool that looks in /proc/cpuinfo.. There may be some deep kernel probing
    tools out there in user-land, but the only tools I've seen that might have
    been useful some day were never complete enough to even be compilable in
    most circumstances.

    It's a shame, really. There was some toolset from IBM I saw years ago, but
    the consultant I met working on it got dropped as part of the dot-bomb
    layoff years ago.
