Test Case: 1. Add INHERIT_append = " kernel-grub" to local.conf and build a new kernel image rpm package. 2. Prepare a deployed target, and make sure your boot area has enough disk space (free space >= 5MB). 3. Download the new kernel image rpm to the target. 4. Before install/update, check boot area and menu root@qemux86-64:~# ls /boot/ grub vmlinuz root@qemux86-64:~# cat /boot/grub/grub.cfg menuentry "Linux" { set root=(hd0,1) linux /vmlinuz root=/dev/hdb2 rw console=tty0 quiet } 4. Install/update bzImage root@qemux86-64:~# rpm -i kernel-image-3.10.11-yocto-standard-3.10.12+git0+285f93bf94_702040ac7c-r0.qemux86_64.rpm Caution! Update kernel may affect kernel-module! update-alternatives: Linking //boot/bzImage to bzImage-3.10.11-yocto-standard 5. After install/update, check boot area and menu root@qemux86-64:~# ls /boot/ -al drwxr-xr-x 4 root root 1024 Sep 18 06:58 . drwxr-xr-x 17 root root 4096 Sep 18 06:41 .. lrwxrwxrwx 1 root root 30 Sep 18 06:58 bzImage -> bzImage-3.10.11-yocto-standard -rw-r--r-- 1 root root 5601808 Sep 18 06:45 bzImage-3.10.11-yocto-standard drwxr-xr-x 4 root root 1024 Sep 18 06:58 grub -rwxr-x--- 1 root root 5601776 Sep 18 06:38 vmlinuz root@qemux86-64:~# cat /boot/grub/grub.cfg menuentry "Update bzImage-3.10.11-yocto-standard-3.10.12+gitAUTOINC+285f93bf94_702040ac7c" { set root=(hd0,1) linux /bzImage-3.10.11-yocto-standard root=/dev/hdb2 rw console=tty0 quiet } menuentry "Linux" { set root=(hd0,1) linux /vmlinuz root=/dev/hdb2 rw console=tty0 quiet } 6. Reboot target, 'Update bzImage-3.10.11-yocto-standard-3.10.12+gitAUTOINC+285f93bf94_702040ac7c' will be in the boot menu. 7. It supports GRUB 0.97 in which use menu.lst rather than grub.cfg as config file. 8. If you install the same rpm more than one time with '--force', there will be multiple kernel images in boot area and menu. //Hongxu The following changes since commit 825cfeb2e6777a55077ecff32d5b2c0e3da13ae8: bitbake: usermanual.xml: Two new sections added to BitBake "Description" (2013-09-17 22:27:56 +0100) are available in the git repository at: git://git.pokylinux.org/poky-contrib hongxu/update-bzimage http://git.pokylinux.org/cgit.cgi/poky-contrib/log/?h=hongxu/update-bzimage Hongxu Jia (1): kernel-grub.bbclass: a method to install/update for bzImage meta/classes/kernel-grub.bbclass | 79 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 79 insertions(+) create mode 100644 meta/classes/kernel-grub.bbclass -- 1.8.1.2
