You might want to mention that dirent.d_ino values are unreliable on some
systems (Linux, Solaris, *BSD get it wrong, but Cygwin gets it right).
The problem is with mount points.  There, stat.st_ino does not always
match the corresponding dirent.d_ino.  This is a problem even with the
latest Linux kernels.

On a related note, I still expect to fix ls -i not to print bogus numbers:

For example,

    $ cd / && ls -1i |grep ' [hrt]$'
     729089 h
    3432450 r
     483331 t
    $ ls -1id h r t
       2 h
       2 r
    6830 t
