Bug#824954: flash-kernel: please provide a way to integrate with GRUB
Package: flash-kernel
Version: 3.66
Severity: wishlist
Hi,
I have an ODROID XU4 (a SBC based on Exynos5422). Since I'm one of those
PC people that would like everything to work like my PC does, I use GRUB
on it (plus, it gives me a nice boot menu when I can choose older kernels
or rescue mode, which is great when you're trying new and different things).
However, there's one thing GRUB doesn't know how to, and that is how to
find the right device tree file and put it in /boot. flash-kernel knows
(by virtue of having its database), but if I install flash-kernel, the first
thing it does is to make a boot.scr, which has higher priority than my GRUB
install (which is in /boot/EFI, lowest in the list of places U-Boot is looking
during boot), essentially overwriting it.
It would be really nice with some way of integrating this. As some sort
of minimal interaction, having some way of installing flash-kernel without
actually flashing (just having the kernel hooks copy the DTB into /boot)
would probably be the easiest; perhaps split into a separate package?
The more advanced integration would probably be if flash-kernel somehow
could flash GRUB (ie., running grub-install and then having its own
boot.scr boot GRUB instead of the kernels), but this sounds like it would
involve policy issues.
