Bug Description

Binary package hint: initramfs-tools

Observed in initramfs-tools 0.98.1ubuntu6
Observed in flash-kernel 2.28ubuntu10
Platform: vexpress (armel)

flash-kernel should do nothing if /etc/flash-kernel.conf doesn't exist? (this may either be a regression, or a platform-specific problem)

initramfs-tools should not even attempt to update the bootloader's initrd image (and so probably shouldn't invoke flash-kernel at all) unless /etc/kernel-img.conf says so (with do_initrd = Yes)

Of course, in a "normal" installation, both configuration files will exist. But for test platforms, and in some other situations, we want to avoid gratuitous flash rewrites.

You are mixing 2 things:

* /etc/kernel-img.conf is deprecated and sholdn't matter these days.

* flash-kernel is not invoked by update-initramfs if /etc/initramfs/post-update.d/ hook extists.

flash-kernel hook should take care to not run if /etc/flash-kernel.conf doesn't exist is a proper condtion.
I don't see an initramfs-tools bug here, thanks for your feedback.

Fair enough -- in that case this may just be an issue with flash-kernel itself or the way it's getting configured.

I guess in this case it's not a problem in initramfs-tools.

Dave, flash-kernel.conf is only used on some boards, not all, so it's not a valid test.

You can disable running flash-kernel by setting FLASH_KERNEL_SKIP= to some value.
