`cd /usr/tests/cddl/usr.sbin/dtrace && kyua test`
Currently common.funcs.t_dtrace_contrib.tst_basename_d is failing due to the
verifiying script does fail:
```
if [ `basename ""` != "." ]; then
echo "basename(\"\") is \".\"; expected \"`basename ""`"\"
fi
if [ `dirname ""` != "." ]; then
echo "dirname(\"\") is \".\"; expected \"`dirname ""`"\"
fi
```
I am not sure the difference of basename(1) & dirname(1) between
implementations in FreeBSD's and DTrace's is intended.
