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

Looking at the patch, it looks like you could instead modify _update_initramfs_tools() to only return flash-kernel in the case that it's needed rather than for all aarch64. Alternatively, enable/disable_update_initramfs could take a force boolean which would perform the operation whether the tool is present or not (though I don't know if dpkg-divert cares about the presence of the binary-to-be-diverted). > > I've tested this w/ a locally-hacked squash image that has flash-kernel > purged and a PPA kernel that allows grub-efi-arm64 to satisfy the > bootloader Recommends.

What's the criteria for determining if a particular arm instance requires flash-kernel or not?
