If my current directory is in a locally-mounted filesystem...

	% df .
	Filesystem            kbytes    used   avail capacity  Mounted on
	/dev/sd2c             602750  511265   31210    94%    /home

and I say `od -a .', I get (as I would expect) a dump of the file `.',
which is a directory.

0000000  nul nul  bs nul nul  ff nul soh   . nul nul nul nul nul nul stx
0000020  nul  ff nul stx   .   . nul nul nul stx  em   { nul dle nul ack
0000040    .   c   s   h   r   c nul   w nul nul  bs ack nul dc4 nul  bs
0000060    .   x   i   n   i   t   r   c nul   s nul   1 nul nul  bs   B

But -- if the current directory is NFS-mounted, as in

	% df .
	Filesystem            kbytes    used   avail capacity  Mounted on
	ptl:/home             602750  511265   31210    94%    /home

Then when I say `od -a .' I see

	0000000

Any idea why??
