Hi Al,

Might it make sense to specify these lookup restrictions when opening
the directory (O_ROOT?) instead of specifying it for each lookup with
AT_* (or supporting both)? This might make it more useful when passing
directory fds between processes that do not use seccomp (where
AT_BENEATH could be enforced).

For my sandboxing use case, I'd be happy with either solution, though.
Is there anything I can do to help move this forward?

Best regards,
JÃrg
