From the client test_log:

From the copytool log, it looks like the copy tool is having problems finding the file:

Looking at all the tests in sanity-hsm, very few tests use $DIR2 to access files on the file system:

	local f=$DIR/$tdir/$tfile
	import_file $tdir/$tfile $f
	local f=$DIR2/$tdir/$tfile

Commenting out the last line above allows the test to complete successfully, but this may defeat what is being tested.
