No.

Yes!
If your kernel has all the drivers needed to mount the root filesystem
compiled in statically (=not as modules), there is usually no need to
have an initramfs.
This is frequent on embedded systems that have no or little variations
of hardware configuration.

[Buildroot] kernel and|or initrd

Hi,

I've got a simple question. I compiled my kernel without use of modules.
Is it necessary ot use an initrd?

This is my grub/menu.lst:

# Begin /boot/grub/menu.lst

default 0
timeout 30
geometry (hd0) 1974 16 63

color cyan/blue white/blue

# The first entry is for TaLux.
title Talux 1.0
        root (hd0,0)
        geometry (hd0) 1974 16 63
        kernel /boot/talux-2.6.24.7 root=/dev/sda1 rw console=tty0
console=ttyS0,38400n8


root and setup of grub work fine. While booting grub announces
"GRUB loading, please wait..." and thats it.

What's the best way to boot?
