This patch does introduce specific kernel kbuild packages that ship the "scripts" and "tools" binaries. The kernel headers fulfill this using symlinks to point to the "scripts" and "tools" of the kernel kbuild package. This is already known from debian kernel packages structure: - Generate a kernel headers package without binaries - Create kernel kbuild packages that ship the "scripts" and "tools" binaries - Using symlinks to point to the "scripts" and "tools" binaries Signed-off-by: Stefan Koch <stefan-koch@siemens.com> --- .../linux/files/debian/control.tmpl | 9 +++- .../linux/files/debian/isar/common.tmpl | 2 + .../linux/files/debian/isar/install.tmpl | 51 +++++++++++++++---- meta/recipes-kernel/linux/linux-custom.inc | 4 ++ 4 files changed, 54 insertions(+), 12 deletions(-)
