Bug#794403: flash-kernel: command "update-initramfs -uk <kver>" result in boot images in false version

[Roger Shimizu <rogershimizu@gmail.com>]

Package: flash-kernel
Version: 3.45
Severity: normal
Tags: patch

Dear Maintainer,

Hook script "initramfs-hook/flash-kernel" will be called when update-initramfs
is invoked. However flash-kernel only build the latest kernel version it find,
rather than the specific version passing from update-initramfs.

For example, after running "update-initramfs -uk <kver>", the <kver> is
successfully passed to "initramfs-hook/flash-kernel", and then "flash-kernel"
script, but "flash-kernel" script simply ignore that version, except adding
a "--force" flag, which is why this patch is here.

I also checked the log for initramfs-hook/flash-kernel, as commit 7bacb9 the
kernel version was actually not passed to "flash-kernel" script, but from
commit e05fc9, this has been changed, which I think it means the flash-kernel
script need to honor what kernel version update-initramfs is working on.

Thanks and looking forward to your comments.

Cheers,
Roger

Subject: [PATCH] initramfs-hook: let flash-kernel build the correct version of
 boot images

Currently, flash-kernel script simply ignores the kernel version passing
from update-initramfs command, but just pick up a latest kernel to build
boot images.

This patch fixes that, by adding a "--force" flag to flash-kernel script.
