Hi,
I believe I have found a bug in mv(1). The version is:
        mv (coreutils) 4.5.3

When logged in as root and trying to mv a files from an NFS mounted directory where root 
dos NOT have permission to remove files since the dir was not exported with the 
"no_root_squash" option, if you try to mv(1) a file, it will 1st copy the file 
succesfully before getting an error on the unlink. Thus mv(1) is not atomic!

Have you seen this before?
