copy the new boot to /boot from /usr/mdec/boot and install your

I didn't do this while doing source-based upgrade 3.0/4.0 and 4.0/5.0
and everything work just fine.
Is this really necessary?
I suspect it depends on what, if any, significant changes were made in
/boot and/or the boot blocks. Which will depend, at least, on your
platform, and perhaps even your hardware, as to whether or not the
changes are "necessary".
I suspect it's just the wise thing to do, even when not needed.
