Test Case:
1. Prepare a deployed target, and make sure your boot area has enough disk
space.
2. Download the new kernel image rpm to the target
3. Before install/update, check boot area and menu
root at qemux86:~# ls /boot/
grub vmlinuz
root at qemux86:~# 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 at qemux86:~# rpm -i kernel-image-3.10.9-yocto-standard-3.10.9+git0+cd502a8814_7144bcc4b8-r0.qemux86.rpm
Caution! Update kernel may affect kernel-module!
update-alternatives: Linking //boot/bzImage to bzImage-3.10.9-yocto-standard
5. After install/update, check boot area and menu
root at qemux86:~# ls /boot/ -al
drwxr-xr-x 4 root root 1024 Sep 12 08:48 .
drwxr-xr-x 17 root root 4096 Sep 12 07:08 ..
lrwxrwxrwx 1 root root 29 Sep 12 08:48 bzImage -> bzImage-3.10.9-yocto-standard
-rw-r--r-- 1 root root 6172096 Sep 12 07:39 bzImage-3.10.9-yocto-standard
drwxr-xr-x 4 root root 1024 Sep 12 08:48 grub
-rwxr-x--- 1 root root 6172096 Sep 12 08:45 vmlinuz
root at qemux86:~# cat /boot/grub/grub.cfg
menuentry "Update bzImage-3.10.9-yocto-standard-3.10.9+gitAUTOINC+cd502a8814_7144bcc4b8" {
set root=(hd0,1)
linux /bzImage-3.10.9-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-3.10.9-yocto-standard-3.10.9+gitAUTOINC+cd502a8814_7144bcc4b8'
will be in the boot menu.
7. It supports GRUB 0.97 in which the grub.cfg doesn't exist and menu.lst
is used.
8. If you install the same rpm more than one time with '--force', there will
be multiple kernel images in boot area and menu.
