I would have thought that the "native file system" part was obvious,
but maybe I need to state it in the documentation.

In any event, I'm not sure I want to get into the business of detailing
how Linux differs from other Unix variants in the bash documentation.
Mac OS X, for instance, displays two lines of output.  I'm sure it's
representative of the BSDs, though I have not checked others.
