3e908d3d7b
This patch skips the `find` task that searches for unlabeled content on systems with SELinux disabled. This fails because labels aren't loaded at that time. The patch also fixed an idempotent test failure that comes from the `selinux` Ansible module repeatedly trying to get SELinux into enforcing mode when it is disabled.
