Hi Pádraig,

I didn't see the above-quoted message until today, via your summary:
  http://www.pixelbeat.org/patches/coreutils/inbox_aug_2010.html
BTW, thanks for keeping that up to date!

Regarding your proposed new test, there is a slightly
more efficient way to do it:

  $ git grep df.--local tests
  tests/du/basic:if df --local . >/dev/null 2>&1; then
  tests/du/slink:if df --local . >/dev/null 2>&1; then
  ...

I.e., you can examine merely the exit status.
If you do that, please encapsulate the test in a function
to be defined in tests/init.cfg, I suppose.
