kernel-grub.bbclass: support /boot area within root partition

2013-11-20T14:02:52+00:00

Previously, it supported the situation that /boot area with separate boot
partition:
...
menuentry "Update bzImage-3.10.10-WR6.0.0.0_standard-3.10" {
    set root=(hd0,1)
    linux /bzImage-3.10.10-WR6.0.0.0_standard root=/dev/sdb1 rw ip=dhcp
}
...

But didn't consider the situation that /boot within root partition:
...
menuentry "Update bzImage-3.10.10-WR6.0.0.0_standard-3.10" {
    set root=(hd0,1)
    linux /boot/bzImage-3.10.10-WR6.0.0.0_standard root=/dev/sdb1 rw ip=dhcp
}
...

This fix supported them both.

kernel-grub.bbclass: add a method to install/update for bzImage

2013-10-26T14:53:24+00:00

While installing a rpm to update kernel on a deployed target, it will update
the boot area and the boot menu with the kernel as the priority but allow
you to fall back to the original kernel as well.

- In kernel-image's preinstall scriptlet, it backs up original kernel to avoid
  probable confliction with the new one.
- In kernel-image's postinstall scriptlet, it modify grub's config file to
  updates the new kernel as the boot priority.
