Description

We should compare the content of the file with the rendered template when in audit mode (as we do in enforce mode, but without actual destination changes). This is what is done by file_from_string_mustache and file_from_template_jinja2.

It seems (tested with 5.0 on Ubuntu 16.04) that this is not the case and that the agent skips content comparison and defines classes based on file existence only, which breaks mustache templated-files auditing.

Looks like the file is rendered but the outcome class is not actually updated after failed comparison.

This is a known issue: https://tracker.mender.io/browse/CFE-2600, fixing it it should not be that hard.
