What is "initrd" in grub.conf?
Can somebody tell me what is the meaning of "initrd" in the grub.conf file?
My grub.conf is like this:
title RedHat Linux(2.4.20-8)
kernel /vmlinuz-2.4.20-8 ro root=LABEL=/
I have read some other examples of grub.conf without this "initrd". Do I really need this line? What if I remove it?
Thank you very much.
