Hi, When `cp --reflink=always` fails because the filesystem does not support reflinks, I'd expect it not to leave anything at the destination path. However, it appears to leave an empty file instead:
$ ls -l total 0 $ echo "some data" > src $ cp --reflink=always src dest cp: failed to clone 'dest' from 'src': Operation not supported $ ls -l total 4 -rw-rw-r--. 1 bgilbert bgilbert 0 Jul 5 01:27 dest -rw-rw-r--. 1 bgilbert bgilbert 10 Jul 5 01:27 src I'm seeing this on both coreutils 9.0 (Fedora 36) and 9.1.31-fa332 built from Git.
