Conceptually the update-alternatives use is wrong as the database is
on /etc and /boot can potentially be in another partition and loaded
directly so relative links are required ...

In fact using symbolic links is not used in generic distributions as
they generate the boot script as post inst action so user can choose
which to boot but for our use case, it makes sense.

It can be adapted to work with it; we could, for example, use the
KERNEL_NAME to be a prefix or suffix for the image and device tree
binaries.
