Yes, that's the way.  Re-define the semantics of the system calls because
you want dodgy feature X.  The UNIX file-system is clean and straight forward.
So too are the system calls.  But, oh no, instead of using the interfaces
provided it's time to mash them into five zillion different flavours, with
no gain in functionality.

How about a "/dev/dir" for directories, "/dev/pipe" for pipes, "/dev/link"
for links?  And, of course, depending on the file type change the semantics
of the system calls.  Add fchdir().

Be real.  Write a function to provide the interface you want, using the
interfaces provided.  Give a programmer a job, but *DON'T* bust the kernel!
