chroot into the build environment

Depending on what may be installed on your system you may use "dchroot" or "schroot" to chroot into the build environment.

For example:

schroot -c lucid-i386

You should chroot into a 64bit build environment to build 64bit kernel package, 32bit build environemt to build 32bit kernel package.

Setup the build tree

This step generates the debian control files required to build the kernel. The clean target is a bit of a misnomer here since we moved the generated files (control.stub, control) out of version control. The clean target actually creates these files. It is a known drawback, and unavoidable.

fakeroot debian/rules clean

Modify debian/changelog

Modify the debian/changelog file to reflect something unique about this build, for example, you may use a launchpad bug number that you might be building this kernel for.

Modify the the first line, for example:

linux (2.6.27-12.28)  UNRELEASED; urgency=low

to

linux (2.6.27-12.28~lpNNNNNNUSERNAME1) UNRELEASED; urgency=low

Build the kernel package
