inode number -> pathname? (4.2BSD)

[jack at boring.UUCP]

Adding a system call to set the current directory to a given
inode/device pair is not only dirty, it also messes up security.

It is possible to create a directory in which a user has all permissions,
but which he cannot reach, because the parent directory is unsearchable.

This can be a very useful feature at times.
