I've been trying for two weeks to compile a new kernel 2.6.11 with module-init-tools. I am getting a kernel panic - not syncing: no init found try passing init = option to kernel. I am currently running 2.4.20-8. Ive googled myself to death with help topics on the subject at hand but I have not found any recent threads that provide the information i need to get the results I want. I even did a search in this forum and used existing threads but none that I came across gave me the answers I need.
Can someone help me out. Remember I am a novice at Linux so break it down for me please step by step. Any suggestions?
Here are the instructions I used from
www.crucialparadigm.com I thought they were well written but I still have the kernel panic issue.

Compile 2.6.7 Kernel w/module-init-tools
Compiling the kernel
Wanted to try out the 2.6 edition kernel? Never knew how to do it? Well heres how! Includes everything from compiling the kernel to configuring your bootloader.
Lets Begin!
cd /usr/src
wget -c
http://kernel.org/pub/linux/kernel/v...-2.6.7.tar.bz2
tar xvfj linux-2.6.7.tar.bz2
cd linux-2.6.7
make clean && make mrproper
make oldconfig ( or make menuconfig )
make bzImage
make modules
make modules_install
( i prefer this method rather then just "make" )
If you get alot of errors about .ko modules when you run make modules_install you need to update your modutils package with module-init-tools, see below.
Now to copy the files over for the kernel itself.
cp .config /boot/config-2.6.7
cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.7
cp System.map /boot/System.map-2.6.7
mkinitrd /boot/initrd-2.6.7.img 2.6.7
You may experience an error such as this:
/dev/mapper/control: open failed: No such file or directory
if you receive that error run the following commands:
rm -rf /boot/initrd-2.6.7.img
mkinitrd --omit-lvm-modules /boot/initrd-2.6.7.img 2.6.7
Now to add it to the grub / lilo configuration.
[Grub]
Your config will look something like this. Please note you need to follow the format for your current config.
title Red Hat Linux (2.6.7)
root (hd0,0)
kernel /vmlinuz-2.6.7 ro root=LABEL=/
initrd /initrd-2.6.7.img
Add your new entry to the top of the kernel list. Set the default to your working kernel. NOTE: the first kernel in the list is "0". (ex. default=1)
Now exit. Type "grub" at the bash prompt.
savedefault --default=0 --once
issue that at the grub prompt then use quit to exit. Once your reboot you need to go back in and set the default to the 2.6 kernel by setting default=0
[lilo]
Your config will look something like this. Please note you need to follow the format for your current config.
image=/boot/vmlinuz-2.6.7
label=2.6.7
append="root=LABEL=/"
read-only
initrd=/boot/initrd-2.6.7.img
Leave the default as is.
/sbin/lilo -v -v
/sbin/lilo -R 2.6.7
Once it reboots and comes back online you can change the default to be 2.6.7 and /sbin/lilo -v -v
The above tells you how to enable failsafe in your kernels. SO that if the box panics the dc tech does not have to console in he just has to reboot the box.
How to install module-init-tools:
cd /usr/src
wget -c
http://www.kernel.org/pub/linux/kern...ols-3.0.tar.gz
tar -zxvf module-init-tools-3.0.tar.gz
cd module-init-tools-3.0
./configure --prefix=""
make moveold
make install
./generate-modprobe.conf /etc/modprobe.conf
How to determine what boot loader you are using?
dd if=/dev/hda bs=512 count=1 2>&1 | grep GRUB
dd if=/dev/hda bs=512 count=1 2>&1 | grep LILO
one of them will kick back something like:
root@w00t [~]# dd if=/dev/hda bs=512 count=1 2>&1 | grep GRUB
Binary file (standard input) matches
root@w00t [~]#
which means its using grub.

Here is my grub.conf:
# grub.conf generated by anaconda

# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/hda2
# initrd /initrd-version.img
#init=options

#boot=/dev/hda
init=0
default=0
