Re: Procedure for upgrading kernel from 2.4 to 2.6

[Tony Terlecki <ajt@mrps.demon.co.uk>]

Thanks John,

What is the purpose of the --initrd option? I know it creates a ramdisk
but what is put in there and why should it be needed? I thought the
kernel would have the necessary drivers compiled in to access everything
needed to continue. I noticed this ramdisk in the stock 2.4.27 kernel
but still don't know its purpose.
