Those ACL flags are in NFSv4 > to make them windows compatible. I checked the windows compatibility with help of SAMBA: "delete_child" and "delete" is really mapped to corresponding NTFS permissions. But this mapping was ignored when I tried to delete a file. I have no idea, why these two permissions supported by FreeBSD. May be, it's a simply non-working clone from Solaris, where it's permissions really works. > > Others will hopefully know more w.r.t. ZFS ACL specifics, rick > -- Best regards, Pavel
