Check Ubuntu's Wiki

There are howtos on Ubuntu's site that describe how to download pre-built, Ubuntu-specific kernels.

More detailed instructions on how the u32 kernel is built can be found on

Vserver Kernel on Ubuntu Dapper with grsecurity


  • 32 Bit Ubuntu Dapper.
  • installed packages:
apt-get install build-essential gcc make g++ libncurses5-dev

Howto Devel

Get the Kernel

cd /usr/src/ && mkdir kernel && cd kernel
tar xfjv linux-
cd linux-

Patch the Kernel

cat ../patch- | patch -p1
cp /boot/vmlinuz-2.6.15-26-server
make oldconfig
make menuconfig

Make the Kernel

make # this will take a long time
make install
make modules_install
mkinitramfs -o /boot/initrd.img-
vi /boot/grub/menu.lst

The Boot entry should look like this

title           Ubuntu,
root            (hd0,0)
kernel          /boot/vmlinuz- root=/dev/sda1 ro quiet splash
initrd          /boot/initrd.img-

Test the Kernel

  • boot Kernel
  • uname -r should show
