# in the same folder as this file. The ISO file must be a valid ISO file that can
# normally be mounted. If the test.iso file is not found the tests will not run.
# The ISO is not included with this repository because of size contstraints.
# It is up to the user or mechanism running these tests to put a valid 'test.iso'
# into this folder.
