cp without overwriting destination permissions
By default, GNU cp (version 8.32) will NOT overwrite destination permissions, so the question is moot:

foo-1.3.1.war
foo-1.3.2.war

How to make cp report an error when file was not copied?
I doubt you can do that with CP, because it only tells you if the command ran sucessfully or not. I would use rsync instead

Is it OK to copy files installed with rpm to another location?
Doing it that way negates most the the advantages of using packages.
Fix the package to put its files where you want them. That way if you use rpm to verify files it will checksum the files in use.

Safest way to move a mount point that is a parent of other mount points on Linux to a new physical device
If you bind mount a directory, then the submounts will not be bound. So create a dummy directory somewhere, and do
mount --bind /var/lib/kubelet/ /mnt/tmptmp_dummy/
Then the contents of the /var/lib/...

You have a race condition: since temp/s is in find's search path, find is listing files, while the spawned cps are adding new files.
