.Sh STANDARDS
POSIX.1e is described in IEEE POSIX.1e draft 17.  Discussion
of the draft continues on the cross-platform POSIX.1e implementation
mailing list.  To join this list, see the
.Fx

.Fx 4.0 ,
and development continues.

.Sh BUGS
These features are not yet fully implemented.  In particular, the shipped
version of UFS/FFS does not support storage of additional security labels,
and so is unable to (easily) provide support for most of these features.
