The description text for admin/config/system/site-information is currently:
Change site name, e-mail address, slogan, default front page, and number of posts per page, error pages.
However, the functionality to change the number of posts is no longer there (as it is changed in the view settings) and so should be changed to:
Change site name, e-mail address, slogan, default front page and error pages.
There is an issue () to add back the setting for the number of posts per page, but that isn't in yet, and, also, would be conditional so this description text would also have to be conditional.
