buildtar 0.0.4

(C) 2004-2006 by Jan-Benedict Glaw jbglaw@lug-owl.de

This script is used to compile a tarball from the currently

prepared kernel. Based upon the builddeb script from

Wichert Akkerman wichert@wiggy.net.

set -e

Some variables and settings used throughout the script

tmpdir="${objtree}/tar-install" tarball="${objtree}/linux-${KERNELRELEASE}-${ARCH}.tar"

Figure out how to compress, if requested at all

case "${1}" in tar-pkg) compress="cat" file_ext="" ;; targz-pkg) compress="gzip" file_ext=".gz" ;; tarbz2-pkg) compress="bzip2" file_ext=".bz2" ;; tarxz-pkg) compress="xz" file_ext=".xz" ;; *) echo "Unknown tarball target "${1}" requested, please add it to ${0}." >&2 exit 1 ;; esac

Clean-up and re-create the temporary directory

rm -rf -- "${tmpdir}" mkdir -p -- "${tmpdir}/boot"

Try to install modules

if grep -q '^CONFIG_MODULES=y' "${objtree}/.config"; then make ARCH="${ARCH}" O="${objtree}" KBUILD_SRC= INSTALL_MOD_PATH="${tmpdir}" modules_install fi

Install basic kernel files

cp -v -- "${objtree}/System.map" "${tmpdir}/boot/System.map-${KERNELRELEASE}" cp -v -- "${objtree}/.config" "${tmpdir}/boot/config-${KERNELRELEASE}" cp -v -- "${objtree}/vmlinux" "${tmpdir}/boot/vmlinux-${KERNELRELEASE}"

Install arch-specific kernel image(s)

case "${ARCH}" in x86|i386|x86_64) [ -f "${objtree}/arch/x86/boot/bzImage" ] && cp -v -- "${objtree}/arch/x86/boot/bzImage" "${tmpdir}/boot/vmlinuz-${KERNELRELEASE}" ;; alpha) [ -f "${objtree}/arch/alpha/boot/vmlinux.gz" ] && cp -v -- "${objtree}/arch/alpha/boot/vmlinux.gz" "${tmpdir}/boot/vmlinuz-${KERNELRELEASE}" ;; parisc*) [ -f "${KBUILD_IMAGE}" ] && cp -v -- "${KBUILD_IMAGE}" "${tmpdir}/boot/vmlinux-${KERNELRELEASE}" [ -f "${objtree}/lifimage" ] && cp -v -- "${objtree}/lifimage" "${tmpdir}/boot/lifimage-${KERNELRELEASE}" ;; vax) [ -f "${objtree}/vmlinux.SYS" ] && cp -v -- "${objtree}/vmlinux.SYS" "${tmpdir}/boot/vmlinux-${KERNELRELEASE}.SYS" [ -f "${objtree}/vmlinux.dsk" ] && cp -v -- "${objtree}/vmlinux.dsk" "${tmpdir}/boot/vmlinux-${KERNELRELEASE}.dsk" ;; mips) if [ -f "${objtree}/arch/mips/boot/compressed/vmlinux.bin" ]; then cp -v -- "${objtree}/arch/mips/boot/compressed/vmlinux.bin" "${tmpdir}/boot/vmlinuz-${KERNELRELEASE}" elif [ -f "${objtree}/arch/mips/boot/compressed/vmlinux.ecoff" ]; then cp -v -- "${objtree}/arch/mips/boot/compressed/vmlinux.ecoff" "${tmpdir}/boot/vmlinuz-${KERNELRELEASE}" elif [ -f "${objtree}/arch/mips/boot/compressed/vmlinux.srec" ]; then cp -v -- "${objtree}/arch/mips/boot/compressed/vmlinux.srec" "${tmpdir}/boot/vmlinuz-${KERNELRELEASE}" elif [ -f "${objtree}/vmlinux.32" ]; then cp -v -- "${objtree}/vmlinux.32" "${tmpdir}/boot/vmlinux-${KERNELRELEASE}" elif [ -f "${objtree}/vmlinux.64" ]; then cp -v -- "${objtree}/vmlinux.64" "${tmpdir}/boot/vmlinux-${KERNELRELEASE}" elif [ -f "${objtree}/arch/mips/boot/vmlinux.bin" ]; then cp -v -- "${objtree}/arch/mips/boot/vmlinux.bin" "${tmpdir}/boot/vmlinux-${KERNELRELEASE}" elif [ -f "${objtree}/arch/mips/boot/vmlinux.ecoff" ]; then cp -v -- "${objtree}/arch/mips/boot/vmlinux.ecoff" "${tmpdir}/boot/vmlinux-${KERNELRELEASE}" elif [ -f "${objtree}/arch/mips/boot/vmlinux.srec" ]; then cp -v -- "${objtree}/arch/mips/boot/vmlinux.srec" "${tmpdir}/boot/vmlinux-${KERNELRELEASE}" elif [ -f "${objtree}/vmlinux" ]; then cp -v -- "${objtree}/vmlinux" "${tmpdir}/boot/vmlinux-${KERNELRELEASE}" fi ;; ) [ -f "${KBUILD_IMAGE}" ] && cp -v -- "${KBUILD_IMAGE}" "${tmpdir}/boot/vmlinux-kbuild-${KERNELRELEASE}" echo "" >&2 echo '* ** ** WARNING ** ** **' >&2 echo "" >&2 echo "Your architecture did not define any architecture-dependent files" >&2 echo "to be placed into the tarball. Please add those to ${0} ..." >&2 echo "" >&2 sleep 5 ;; esac

Create the tarball

( cd "${tmpdir}" opts= if tar --owner=root --group=root --help >/dev/null 2>&1; then opts="--owner=root --group=root" fi tar cf - boot/* lib/* $opts | ${compress} > "${tarball}${file_ext}" )

echo "Tarball successfully created in ${tarball}${file_ext}"

exit 0
