Use explicit named keyword arguments and values in tests
Use explicit named keyword arguments and values in tests

Using explicit named arguments when creating a LinuxDistribution makes
the tests more readable than using positional unnamed arguments.

Using 'path-to-non-existing-file' as a variable value for non-existing
test file paths is easier to understand than a terse 'non' value.
