Hi, as reported in https://bugzilla.redhat.com/show_bug.cgi?id=1141368 , there is a possible race condition in mv in the case of hardlinks.
Bug is reproducible even on ext4 filesystem (I guess it is filesystem independent), even with the latest coreutils. There was already attempt to fix the non-atomicity of mv for hardlinks ( http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/12985 ), from the current reproducer it looks like the fix is probably incomplete. Regards, Ondrej Vasik
