Looks like I was incorrect on that one; from 929424#10 :
"initramfs-tools doesn't store temporary files on /boot"

Apologies for that.

Today I learned something new and that is that plymouth includes
GPU modules AND their firmware in the initramfs.
And with the now much larger firmware packages/files, that made
the actual problem much more urgent.

And that is IMO still the actual issue.

Due to a VERY similar bug report, I was made aware of some rather
horrific advise ... in the official Debian documentation:
https://bugs.debian.org/1076582#27

On the d-i size (in code) things were apparently already evolved into
this century, but I still think 512MB for /boot partition is problematic.
And even more so when plymouth is in the mix, where (too many?) firmware
files get included in initramfs.

So I bumped up the severity, but not reassigned it as I think it's useful
if all these reports came in on the same Mailing List, which in this case
is the debian-kernel ML ...

That's still correct (though).
But it may be useful to extend the NEWS to be more explicit and verbose
about the potential consequences.
