The descriptions returned by the install tasks run by the built-in Web update currently show up in red. I understand this change has been made to better emphasize warning messages, but this currently looks like there's been four errors during the installation. At least for a test run, none of the mentioned settings are actually needed to give Magnolia a spin.

I suggest to change the status of these messages - and possibly others as well - from WARN to INFO, or to revert the change.
