Hi Greg,

Thanks for your series!

I'll bite ;-)

Does anyone actually use these scripts (outside of x86)?
I assume the architectures that have them, only have them because they
were copied from x86 while doing the initial ports ("oh, a file I don't
have to modify at all.").
But installing the kernel can be very platform-specific.
Do you need the vmlinux, vmlinux.gz, Image, zImage, uImage, ...?
With separate or appended DTB?

Even on x86, the script will bail out with "Cannot find LILO." if you're
using Grub.

Anyway, having less of them is good.

Gr{oetje,eeting}s,
