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.
Best,
--Benjamin Gilbert
