set up new kernel with grub

[Michael]

Hi,

I compiled a new kernel: 2.6.20.3, and hope to test it without removing 
my old kernel.

Here is what I did by following 
http://searchenterpriselinux.techtarget.com/tip/0,289483,sid39_gci1204148,00.html :

I built the kernel in a local directory, say "mydir", with kernel 
"bzImage-2.6.20.3" and map file "System.map".

> su          (#become a root)

> cp mydir/bzImage-2.6.20.3 /boot/bzImage-2.6.20.3
> cp mydir/System.map /boot/System.map-2.6.20.3

> cd /boot
> ln -s /boot/bzImage-2.6.20.3 /boot/bzImage
> ln -s /boot/System.map-2.6.20.3 /boot/System.map

> vi grub/menu.lst

add a new entry as
**************************************
title Red Hat Linux (2.6.20.3)
   root (hd0, 0)
   kernel /boot/bzImage ro root=LABEL=/
   initrd /boot/initrd-2.6.20.3.img
**************************************

> create an initial ram disk image by
mkinitrd -k /boot/bzImage -i /boot/initrd-2.6.20.3

It reports wrong usage of "mkinitrd", and no initrd-2.6.20.3.img is 
created.

Any idea about what's wrong with the "mkinitrd" command ?


Thanks.

Mike
