This is not needed at all from Linux 4.7.  The open operation on
/dev/ptmx automatically looks up the sibling pts/ directory.  (Also,
every mount of devpts is a 'new instance'.)

It seems to me that the change in debootstrap ought to be reverted, as
it will not be needed in future and it is causing problems for existing
configurations.
