>Description:
After running a full test suite pass on a non-emulated Alpha, I noticed some shell test failures.  In the case of bin/sh/t_input:nul_elimination, it seems to be because it wants to create a file called "helper.sh" in the current working directory.  This failed because I did not run the tests as root.

The test suite was run by performing the following commands as a non-root user:

cd /usr/tests
atf-run | atf-report

>How-To-Repeat:
cd /usr/tests/bin/sh
./t_input nul_elimination


>Fix:
Not provided.
