The docs state that you need to make the config file _readable_
and then proceeds to make the file writable.
This changes it to make the file to be owned by root and readable by
anyone. This is the default for unix / linux and suggested practice
for files in /etc.
The text just sets the ownership and ignores that defaults on unix
are to have newly created dirs be readable by everyone.
This closes the database to unauthorized users on multi-user systems.
