 Jason, can you demonstrate how you ran the test, along with
 permissions, owners, etc, on any directories you consider
 relevant.
 
 It would also be mildly interesting to understand your interest
 in running a test which is currently broken (by sh updates) and
 which I have yet to take the time to work out what to do about.
 Though I guess that perhaps it is still intended to work in -10.
 
 (Most probably the whole test will simply be dropped, and replaced
 by one which verifies that \0 chars are treated as errors, but
 that test took quite a bit of effort to generate to make sure
 representatives of just about all the weird places a \0 might
 appear, and make sure they were all being ignored, that I kind
 of hate to lose it!)
 
   | Normally, atf-run creates a temporary directory which the test can
   | write into.
 
 Yes.
 
   | mkdir /tmp/test
   | cd /tmp/test
   | /usr/tests/bin/sh/t_input nul_elimination
 
 That would be an ugly way to run any ATF test.
 
   | It would be nice if there were a way to ask atf-run to run a single
   | test case by name, but we don't have that as far as I know.
 
 You mean like:

 The first of those used my /bin/sh which is kind of ancient (pre 10
 branch), and so failed, because it failed to fail, the second used
 the same sh as is /bin/sh in HEAD, and so successfully failed as expected.
