--- Comment #6 from Xin LI <delphij@FreeBSD.org> ---
I think this can probably be addressed by changing `zfsctl_ctldir_mode`
(sys/contrib/openzfs/module/os/freebsd/zfs/zfs_ctldir.c) to `S_IRUSR | S_IX=
USR`
(or `S_IRUSR | S_IXUSR | S_IRGRP | S_IXGRP`) with a loader tunable, so the =
.zfs
is only accessible by root (or root plus the wheel group).
