Sure. flash-kernel recognizes Mustang boards and will generate uImage
and uInitrd files for it, which are required for booting with
I still don't understand:
1) why does which not find flash-kernel if it's present in the ephemeral image
(meaning it will also be present in the target filesystem
2) What is the problem with flash-kernel such that you need to dpkg-divert it?

maybe we can try this patch with alternative path to disable arch-

I tried dpkg-divert with my mustang and flash-kernel (see in attachment)
It's ok for dpkg-divert even that package isn't installed.

Hi Dan,
Could you summarize the problem with flash-kernel and this system?

agree with dannf
we should refactor disable_update_initramfs and enable_update_initramfs.
we should not use `which` to determine the executable path.
and always disable update_initramfs or arch-specific package, even those pkgs
are not installed.
Is it a good solution that we specific absolute
Maybe this WIP patch will work fine and we don't need to refactor
disable_update_initramfs.
this patch also consider if there is already initramfs or flash-kernel
installed.
Try to guarantee order
But this might override and deactivate bugfix for LP:1640519
** Patch added:
There is no need to install flash-kernel here.
It will install flash-kernel in "ephemeral image" which didn't have kernel
installed.

So that means, curtin will never install flash-kernel into real system because
Attached is a patch for curtin that works for me, though it could use
some cleanup. It installs flash-kernel in the same place GRUB gets
installed for EFI-based systems, which seems like the appropriate place.
Before installint it, it diverts /usr/sbin/flash-kernel so that flash-

After reading log in #14, and some code from cloud-init and maas
I still cannot find any code that will let cloud-init try to install

and it seems the error because squashfs didn't have any kernel installed.
So `linux-version` cannot find any kernel version to

In case it helps, attached is the MAAS preseed I used for testing the
PPA kernel w/ the updated Recommends. I also removed flash-kernel from
the corresponding MAAS cloud image by locally unsquashfs/purge flash-
kernel/mksquashfs and dd'ing back over the existing image.
** Changed in: linux
I tested this locally by creating a MAAS preseed that adds my PPA. And
it works sort of. The kernel no longer causes flash-kernel to be
installed, but unfortunately flash-kernel is *pre-baked* in the arm*
cloud images, so we'd have to remove it from them too.
