FWIW, this has been triggered by the following changes in coreutils:

,----
| * Noteworthy changes in release 9.3 (2023-04-18) [stable]
|
| ** Changes in behavior
|
|   'cp -n' and 'mv -n' now issue an error diagnostic if skipping a file,
|   to correspond with -n inducing a nonzero exit status as of coreutils 9.2.
|
| * Noteworthy changes in release 9.2 (2023-03-20) [stable]
|
| ** Changes in behavior
|
|   'cp -n' and 'mv -n' now exit with nonzero status if they skip their
|   action because the destination exists, and likewise for 'cp -i',
|   'ln -i', and 'mv -i' when the user declines.  (POSIX specifies this
|   for 'cp -i' and 'mv -i'.)
`----

I looked for 'cp -n' in the initramfs-tools source and could not find
it.  It turns out that the actual culprit is the file
/usr/share/initramfs-tools/hooks/klibc-utils which uses the -n option,
apparently with good reason, namely not to overwrite files from busybox.

There do not seem to be any ill effects beside the warnings.

Cheers,
