From d38f1dd24dd6ed94408aa49aad33e46634a129ff Mon Sep 17 00:00:00 2001 From: Marcin Juszkiewicz Date: Fri, 5 Dec 2008 17:15:41 +0100 Subject: Auto resizing ext2/ext3 images (from Poky) During my work for OpenedHand I wrote one usefull thing which we used for ext2/ext3 images - autosizing. In few words: it checks how big rootfs is, adds IMAGE_EXTRA_SPACE amount of kilobytes to it and gives that size to genext2fs. --- conf/bitbake.conf | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'conf/bitbake.conf') diff --git a/conf/bitbake.conf b/conf/bitbake.conf index 3646522d93..2c6979a9ca 100644 --- a/conf/bitbake.conf +++ b/conf/bitbake.conf @@ -308,9 +308,9 @@ IMAGE_CMD = "" IMAGE_CMD_jffs2 = "mkfs.jffs2 -x lzo --root=${IMAGE_ROOTFS} --faketime --output=${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.jffs2 ${EXTRA_IMAGECMD}" IMAGE_CMD_yaffs2 = "mkyaffs2image ${EXTRA_IMAGECMD} ${IMAGE_ROOTFS} ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.yaffs2" IMAGE_CMD_cramfs = "mkcramfs ${IMAGE_ROOTFS} ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.cramfs ${EXTRA_IMAGECMD}" -IMAGE_CMD_ext2 = "genext2fs -b ${IMAGE_ROOTFS_SIZE} -d ${IMAGE_ROOTFS} ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.ext2 ${EXTRA_IMAGECMD}" +IMAGE_CMD_ext2 = "genext2fs -b ${ROOTFS_SIZE} -d ${IMAGE_ROOTFS} ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.ext2 ${EXTRA_IMAGECMD}" IMAGE_CMD_ext2.gz = "rm -rf ${DEPLOY_DIR_IMAGE}/tmp.gz && mkdir ${DEPLOY_DIR_IMAGE}/tmp.gz; genext2fs -b ${IMAGE_ROOTFS_SIZE} -d ${IMAGE_ROOTFS} ${DEPLOY_DIR_IMAGE}/tmp.gz/${IMAGE_NAME}.rootfs.ext2 ${EXTRA_IMAGECMD}; gzip -f -9 ${DEPLOY_DIR_IMAGE}/tmp.gz/${IMAGE_NAME}.rootfs.ext2; mv ${DEPLOY_DIR_IMAGE}/tmp.gz/${IMAGE_NAME}.rootfs.ext2.gz ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.ext2.gz; rmdir ${DEPLOY_DIR_IMAGE}/tmp.gz" -IMAGE_CMD_ext3 = "genext2fs -b ${IMAGE_ROOTFS_SIZE} -d ${IMAGE_ROOTFS} ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.ext3 ${EXTRA_IMAGECMD}; tune2fs -j ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.ext3" +IMAGE_CMD_ext3 = "genext2fs -b ${ROOTFS_SIZE} -d ${IMAGE_ROOTFS} ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.ext3 ${EXTRA_IMAGECMD}; tune2fs -j ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.ext3" IMAGE_CMD_ext3.gz = "rm -rf ${DEPLOY_DIR_IMAGE}/tmp.gz && mkdir ${DEPLOY_DIR_IMAGE}/tmp.gz; genext2fs -b ${IMAGE_ROOTFS_SIZE} -d ${IMAGE_ROOTFS} ${DEPLOY_DIR_IMAGE}/tmp.gz/${IMAGE_NAME}.rootfs.ext3 ${EXTRA_IMAGECMD}; tune2fs -j ${DEPLOY_DIR_IMAGE}/tmp.gz/${IMAGE_NAME}.rootfs.ext3; gzip -f -9 ${DEPLOY_DIR_IMAGE}/tmp.gz/${IMAGE_NAME}.rootfs.ext3; mv ${DEPLOY_DIR_IMAGE}/tmp.gz/${IMAGE_NAME}.rootfs.ext3.gz ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.ext3.gz; rmdir ${DEPLOY_DIR_IMAGE}/tmp.gz" IMAGE_CMD_squashfs = "mksquashfs ${IMAGE_ROOTFS} ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.squashfs ${EXTRA_IMAGECMD} -noappend" IMAGE_CMD_squashfs-lzma = "mksquashfs-lzma ${IMAGE_ROOTFS} ${DEPLOY_DIR_IMAGE}/${IMAGE_NAME}.rootfs.squashfs-lzma ${EXTRA_IMAGECMD} -noappend" -- cgit v1.2.3
