builddeb 1.3

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 installed or removed

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

/etc/kernel/{pre,post}{inst,rm}.d/ directories (or an alternative location

specified in KDEB_HOOKDIR) that will be called on package install and

removal.

set -e

create_package() { local pname="$1" pdir="$2"

cp debian/copyright "$pdir/usr/share/doc/$pname/"
cp debian/changelog "$pdir/usr/share/doc/$pname/changelog.Debian"
gzip -9 "$pdir/usr/share/doc/$pname/changelog.Debian"
sh -c "cd '$pdir'; find . -type f ! -path './DEBIAN/*' -printf '%P\0' \
	| xargs -r0 md5sum > DEBIAN/md5sums"

# Fix ownership and permissions
chown -R root:root "$pdir"
chmod -R go-w "$pdir"

# Create the package
dpkg-gencontrol -isp -p$pname -P"$pdir"
dpkg --build "$pdir" ..

}

Some variables and settings used throughout the script

version=$KERNELRELEASE revision=$(cat .version) if [ -n "$KDEB_PKGVERSION" ]; then packageversion=$KDEB_PKGVERSION else packageversion=$version-$revision fi tmpdir="$objtree/debian/tmp" fwdir="$objtree/debian/fwtmp" packagename=linux-image-$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" "$tmpdir/boot" "$tmpdir/usr/share/doc/$packagename" mkdir -p "$fwdir/DEBIAN" "$fwdir/lib" "$fwdir/usr/share/doc/$fwpackagename" if [ "$ARCH" = "um" ] ; then mkdir -p "$tmpdir/usr/lib/uml/modules/$version" "$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" # Not all arches include the boot path in KBUILD_IMAGE if ! cp $KBUILD_IMAGE "$tmpdir/boot/vmlinuz-$version"; then cp arch/$ARCH/boot/$KBUILD_IMAGE "$tmpdir/boot/vmlinuz-$version" fi 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

Note: hook scripts under /etc/kernel are also executed by official Debian

kernel packages, as well as kernel packages built using make-kpkg

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

set -e

Pass maintainer script parameters to hook scripts

export DEB_MAINT_PARAMS="$*"

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

Try to determine maintainer and email values

if [ -n "$DEBEMAIL" ]; then email=$DEBEMAIL elif [ -n "$EMAIL" ]; then email=$EMAIL else email=$(id -nu)@$(hostname -f) fi if [ -n "$DEBFULLNAME" ]; then name=$DEBFULLNAME elif [ -n "$NAME" ]; then name=$NAME else name="Anonymous" fi maintainer="$name <$email>"

Generate a simple changelog template

cat < debian/changelog linux-upstream ($packageversion) unstable; urgency=low

• Custom built Linux kernel.

-- $maintainer $(date -R) EOF

Generate copyright file

cat < debian/copyright This is a packacked upstream version of the Linux kernel.

Generate a control file

cat < debian/control Source: linux-upstream Section: kernel Priority: optional Maintainer: $maintainer Standards-Version: 3.8.4 Homepage: http://www.kernel.org/ EOF

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
