builddeb 1.2

Copyright 2003 Wichert Akkerman wichert@wiggy.net

Simple script to generate a deb package for a Linux kernel. All the

complexity of what to do with a kernel after it is installer or removed

is left to other scripts and packages: they can install scripts in the

/etc/kernel/{pre,post}{inst,rm}.d/ directories that will be called on

package install and removal.

set -e

Some variables and settings used throughout the script

version=$KERNELRELEASE revision=cat .version tmpdir="$objtree/debian/tmp" fwdir="$objtree/debian/fwtmp" packagename=linux-$version fwpackagename=linux-firmware-image

if [ "$ARCH" == "um" ] ; then packagename=user-mode-linux-$version fi

Setup the directory structure

rm -rf "$tmpdir" "$fwdir" mkdir -p "$tmpdir/DEBIAN" "$tmpdir/lib" "$tmpdir/boot" mkdir -p "$fwdir/DEBIAN" "$fwdir/lib" if [ "$ARCH" == "um" ] ; then mkdir -p "$tmpdir/usr/lib/uml/modules/$version" "$tmpdir/usr/share/doc/$packagename" "$tmpdir/usr/bin" fi

Build and install the kernel

if [ "$ARCH" == "um" ] ; then $MAKE linux cp System.map "$tmpdir/usr/lib/uml/modules/$version/System.map" cp .config "$tmpdir/usr/share/doc/$packagename/config" gzip "$tmpdir/usr/share/doc/$packagename/config" cp $KBUILD_IMAGE "$tmpdir/usr/bin/linux-$version" else cp System.map "$tmpdir/boot/System.map-$version" cp .config "$tmpdir/boot/config-$version" cp $KBUILD_IMAGE "$tmpdir/boot/vmlinuz-$version" fi

if grep -q '^CONFIG_MODULES=y' .config ; then INSTALL_MOD_PATH="$tmpdir" make KBUILD_SRC= modules_install if [ "$ARCH" == "um" ] ; then mv "$tmpdir/lib/modules/$version"/* "$tmpdir/usr/lib/uml/modules/$version/" rmdir "$tmpdir/lib/modules/$version" fi fi

Install the maintainer scripts

for script in postinst postrm preinst prerm ; do mkdir -p "$tmpdir/etc/kernel/$script.d" cat < "$tmpdir/DEBIAN/$script" #!/bin/sh

set -e

test -d /etc/kernel/$script.d && run-parts --arg="$version" /etc/kernel/$script.d exit 0 EOF chmod 755 "$tmpdir/DEBIAN/$script" done

name="Kernel Compiler <$(id -nu)@$(hostname -f)>"

Generate a simple changelog template

cat < debian/changelog linux ($version-$revision) unstable; urgency=low

• A standard release

-- $name $(date -R) EOF

Generate a control file

if [ "$ARCH" == "um" ]; then

cat < debian/control Source: linux Section: base Priority: optional Maintainer: $name Standards-Version: 3.6.1

Package: $packagename Provides: kernel-image-$version, linux-image-$version Architecture: any Description: User Mode Linux kernel, version $version User-mode Linux is a port of the Linux kernel to its own system call interface. It provides a kind of virtual machine, which runs Linux as a user process under another Linux kernel. This is useful for kernel development, sandboxes, jails, experimentation, and many other things. . This package contains the Linux kernel, modules and corresponding other files version $version EOF

else cat < debian/control Source: linux Section: base Priority: optional Maintainer: $name Standards-Version: 3.6.1

Package: $packagename Provides: kernel-image-$version, linux-image-$version Suggests: $fwpackagename Architecture: any Description: Linux kernel, version $version This package contains the Linux kernel, modules and corresponding other files version $version EOF fi

Fix some ownership and permissions

chown -R root:root "$tmpdir" chmod -R go-w "$tmpdir"

Do we have firmware? Move it out of the way and build it into a package.

if [ -e "$tmpdir/lib/firmware" ]; then mv "$tmpdir/lib/firmware" "$fwdir/lib/"

cat <<EOF >> debian/control

Package: $fwpackagename Architecture: all Description: Linux kernel firmware, version $version This package contains firmware from the Linux kernel, version $version EOF

dpkg-gencontrol -isp -p$fwpackagename -P"$fwdir"
dpkg --build "$fwdir" ..

fi

Perform the final magic

dpkg-gencontrol -isp -p$packagename dpkg --build "$tmpdir" ..

exit 0
