    Subjectcutting down on boot messages
    If I boot my system, there are copious messages. 

    For example:

    md: Autodetecting RAID arrays.
    md: autorun ...
    md: considering hdc6 ...
    md: adding hdc6 ...
    md: hdc5 has different UUID to hdc6
    md: hdc3 has different UUID to hdc6
    md: hdc1 has different UUID to hdc6
    md: adding hda6 ...
    md: hda5 has different UUID to hdc6
    md: hda3 has different UUID to hdc6
    md: hda1 has different UUID to hdc6
    md: hdi2 has different UUID to hdc6
    md: hdi1 has different UUID to hdc6
    md: hde2 has different UUID to hdc6
    md: hde1 has different UUID to hdc6
    md: created md5
    md: bind<hda6>
    md: bind<hdc6>
    md: running: <hdc6><hda6>
    md5: setting max_sectors to 128, segment boundary to 32767
    raid1: raid set md5 active with 2 out of 2 mirrors

    Now these messages are often uninteresting - but sometimes they are.
    So just deleting them, or requiring a recompile or reboot is not good
    enough.
    Also, I noted that these messages were almost always grouped together.

    Suppose these messages were removed from the normal output, but instead
    stored in a buffer in the kernel.

    Then, you could do

    dmesg.raid

    to get at the raid-messages,

    and

    dmesg.raid --clear

    to clear the buffer.

    The same goes for other groups of messages, like the whole APIC/IRQ
    routing block, ide messages, usb messages etc.

    Would this keep the interesting information, but cut down on the amount
    of messages? I'm now at 22k of dmesg, including raid, usb, apic etc, for
    a single CPU system.

    I'd be interested in everyone's opinion on this!

    tomorrow to ask for it!" (New business manager, Hallmark Greeting
