image-bootfiles class copy files listed in IMAGE_BOOT_FILES to the IMAGE_BOOT_FILES_DIR directory of the root filesystem. This is useful when there is no explicit boot partition but all boot files should instead reside inside the root filesystem. Signed-off-by: Marcus Folkesson <marcus.folkesson@gmail.com> --- Notes: v3: - Skip the intermediate bootfiles() function - Rename variable names to be consistent - Various python optimizations v4: - Correct usage description - Create image_dst before copy v5: - Check if install_files is [] rather than None - Print warning if overwriting files - run as ROOTFS_POSTPROCESS_COMMAND instead meta/classes/image-bootfiles.bbclass | 41 ++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 meta/classes/image-bootfiles.bbclass
