    What is initrd in grub.conf?


    I'm looking at my grub.conf file, and would like to know what the initrd /initrd-2.4.20-8.img
    line does. It appears as though the kernel boots from the line above. So what does initrd do? Thanks.

    It's an initial ramdisk, I believe it provides startup utilities and init sequences, something like that. :P

    Ok, I see. I'm guessing that the disk checking program would be an ideal use of the RAMDISK. The volumes probably aren't mounted before you see the disk checking countdown on Redhat, so therefore the system is using the RAMDISK. Thanks.
