It appears to only work if you have one or the other. At least that was the last time I checked. That's not true. rsync copies all EAs, of which ACLs are simply examples of. I haven't studied copyfile.c for hours, but the limited attention I've given it tells me that ACLs do indeed receive some special addition, they're not merely blindly copied just like other EAs. For copying files directly, copyfile_security() actually loops over the ACEs in an ACL and only copies noninherited ones. When archiving in AppleDouble files (this is the path used by rsync I think), ACLs are packed in copyfile_pack_acl(). Also when unpacking the AppleDouble files, ACLs get extra treatment. So it's not entirely unplausible to me that there's still bugs lurking in copyfile(). This email sent to site_archiver@lists.apple.com
