[Message part 1 (text/plain, inline)]
Hi

After upgrading to coreutils 9.2-2 on Arch Linux the following:
mkdir -p src dst
touch {src,dst}/bar
cp --recursive --backup src/* dst
fails with:
cp: cannot create regular file 'dst/foo/bar': File exists

Running strace on cp I noticed:
renameat2(4, "foo/bar", 4, "foo/bar~", 0) = -1 ENOENT (No such file or 
directory)

In coreutils 9.1-3 the syscall succeeds:
renameat2(4, "bar", 4, "bar~", 0)       = 0

I assume renameat2 is called with the wrong oldpath and newpath in 9.2 
and that it should just be the basename and not the full relative path.

Cheers
Kristian Klausen
