Hi,
this is a bug for this (merged) MR on salsa:
https://salsa.debian.org/installer-team/flash-kernel/-/merge_requests/80
From the MR/commit description:
> Since Debian Linux commit 85b86360b6e4c1c63a698aa98edbdec963d72ebe,
> /usr/lib/linux-image-$kvers is a symlink to /lib/modules/$kvers/dtb and
> without -H, find will not traverse into it.
I'm not the best person to file this bug because the platforms I have here
(imx8mq, rk3588, a311d, ls1028a, imx8m+) are all not supported by flash-kernel,
so I can only use them with flash-kernel with a patched machine file. This is
why you will see a strange version in my logs.
I am maintaining a Debian "derivative" (we only patch five packages) for the
MNT Reform open hardware laptops and one of the packages we patch is
flash-kernel. We also patch it with the patch from above MR and this is what
convinces me that that MR fixes this problem.
Without that patch, we see this:

The problem is, that "find /usr/lib/linux-image-6.18.3-mnt-reform-arm64" sees
a symlink and will not descend into it. This is why the problem is fixed by
adding the -H flag to find. With that flag in place we get:
