Only if the kernel is compiled with CONFIG_DEVPTS_MULTIPLE_INSTANCES
(which will be clearly superflous after the cleanup patches because
the amount of addition code is minimal) _and_ you mount with
-o newinstance, and then you have another -o ptmxmode=foo option
to make it useable.
Really, even if we're really cautious there should be no compiletime
and just a single mount time option, but I'm not even sure that is
needed with the default zero mode.
