Hmm. Well, strictly speaking, the link created under pseudo *does* get 
tracked. Hmm. But an implicit request to track also the thing linked to 
is not a horrible idea. Although you'd still be able to beat it:

	$ touch file1
	$ ln file1 file2
	$ pseudo
	# ln file2 file3
	# chmod 777 file3
	# rm file2 file3
	# ls -l file1

The general case of "find everything this link also refers to" is 
clearly out of scope. That said... Hmm. I think my main feeling is, if 
we want
to link to the file, and we want the changes to the linked file to
survive, we should probably either create that file under pseudo, or 
explicitly claim it with pseudo when we start wanting to do the 
tracking.
(You can trivially do this to a tree with chown -R root tree).
