Of course : /lib/modules/<kernel version> is installed via package. You
have to do it manually to get rid of this error. And without it you can't
achieve a bootable kernel.

I don't have to do it *manually* I give funny names during build so the
.deb include all is needed. And I only need backup of the package, not
the /boot files. Obviously /boot is for operational files not for backup
ones.

Ok to cover grub menu you just have to had it in /etc/grub.d.
You simply copy a block menuentry from /boot/grub/grub.cfg and put it in
something like /etc/grub.d/40_custom. In the copy you can change kernel
params, etc. update-grub will include it in generated grub.cfg.

Building a kernel is much less work than believed. And much much less
complicated too. It requires apt install kernel sources, apt install deps
for build, then do the build. I build with my custom make commands but I
heard there is a dedicated debian stance to even more simplify this
point. Overall it is much less work than manually following updates on a
breaked /boot.
