custom kernel install - query

[Sengottuvelan S]

Hi all

I am trying to install new custom kernel in my ubundu. I am able to
see "vmlinuz-2.6.x.x-custom-velan"
and System.map-2.6.x.x-custom-velan in my /boot after
#make-kpkg --initrd --append-to-version=-custom_velan kernel_image
kernel_headers

i don;t see initrd for this new custom kernel in /boot and also no entry is
created in /boot/grub/grub.cfg.
I also don't see any new file "menu.lst" in /boot/grub directory.

I am using generic kernel as below.

root at ubuntu:/usr/src/linux# uname -a
Linux ubuntu 2.6.32-24-generic #39-Ubuntu SMP Wed Jul 28 05:14:15 UTC 2010
x86_64 GNU/Linux

Can you throw some light on this.

never use make-kpkg by myself, but after reading
http://man.he.net/man1/make-kpkg, IMO you need to study about
"kernel_image" target. Seems it will be the one you needed.

NB: even without make-kpkg, now kernel has "make deb-pkg"
target...seems it will fit your need too.

I had the same problem a while ago, make-kpkg doesn't build the initrd file in 
my debian box.

To solve this i had to use mkinitramfs and then, add the initrd file by hand 
in the grub.conf.

make-kpg kernel_image kernel_headers will make debs in the folder above 
the source tree when done and you will need to go install those manually 
(sudo dpkg -i linux-image-2.6.37-rc6-customwhatever.deb) and then you 
should be set.

I have noticed that on Ubuntu 10.10 there is no menu.lst for grub and I 
have no idea how to update it. Thankfully, using dpkg to install the 
kernel updates grub for you. I have been having an issue with grub not 
displaying the menu on i386 and booting the first entry, but on x86_64 
it's displaying a list. Hope that helps

Ubuntu 10.10 uses Grub2, which has a different way of managing bootloaders,
see this article for more info: https://help.ubuntu.com/community/Grub2

On Ubuntu 10.10, you need to update /etc/default/grub and then use
'sudo update-grub' to update your configuration.

I see, thanks for the info on grub2 guys! If the files were copied to 
/boot it sounds like the original poster just needs to update grub. I 
still don't understand how the files got copied tho, I always have to 
dpkg them myself (not done at the make-kpkg stage) and grub is taken 
care of then.

ubuntu now uses grub 2 whose config file is called grub.cfg, but it shoul't be 
edited by hand. If you wan to edit, you should edit the files in /etc/grub and 
run update-grub (if you simply wan to add a kernel or an initrd image, just 
run grub-update and they will be added to grub.cfg)

On Ubuntu systems, just follow the following steps for building the new
kernel images.

Note: I build the kernel image as a ROOT, here. So, I did not use the
SUDO.

1) Download the required kernel version TAR ball from the www.kernel.org
and extract it in the /usr/src directory. 
2) Change into the newly created directory.
3) Build the kernel with the following set of commands from
/usr/src/linux directory. Here the linux is a link to the newly created
directory. 
4) Then run the following commands. 
# make mrproper
# make clean
# make menuconfig  - Just exit from the GUI menu by pressing YES.
# make prepare
# make menuconfig	 - Do the modifications, whatever you want.
# make clean
# make bzImage   (capital L letter in bzImage)
# make modules
# make modules_install
# make install

Then, build the initrd file with the following command from anywhere,
however you need to copy the build initrd file explicitly to the /boot
directory.
# mkinitramfs -o initrd-img-kernel-version kernel-version

Finally, update the grub with the following command from /boot directory
and restart the system. By default it boots into the newly build kernel
image.
# update-grub

For more information on Grub follow the link
https://help.ubuntu.com/community/Grub2

Hi Sengottuvelan,

Can you rename the initrd file to initrd-img-2.6.35.9 from initrd-img-2.6.35.9-custom. For other files, like System.map and config, they do not have the -custom extension. So, just remove the -custom from your initrd and run the update-grub command again.   

Thanks and Regards,
Srinivas G

This may be useful. Please recheck how you are building the kernel and
installing to system.
