I think you're thinking of recent mv versions, or a patched coreutils? cp in current coreutils git never reflinks http://git.savannah.gnu.org/cgit/coreutils.git/tree/src/cp.c#n785 unless explictly requested http://git.savannah.gnu.org/cgit/coreutils.git/tree/src/cp.c#n957 (line numbers valid as of today's git master) I believe the rationale is that people invoking cp(1) might expect to have two entirely independent copies of all the file's disk blocks afterwards, such that a kernel- or hardware-level bit-flip in one would leave the other untouched - as opposed to reflinking, in which *user-space* changes to one leave the other untouched. I don't personally think that rationale is sufficiently convincing to outweigh the simplicity of reflinking by default, but I don't maintain coreutils, and perhaps I'd think differently if I did. -- Simon McVittie Collabora Ltd. <http://www.collabora.com/> _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
