Clean Up settings.php
Typically, when I build sites, I delete all of the comments, and unused options in settings.php. If I ever need to know available option, or what an option does, I can look in the default.settings.php file.
So, for this site, if I do that, I'm left with the following in my settings.php file:
<?php
/**
* Salt for one-time login links, cancel links, form tokens, etc.
*/
$settings['hash_salt'] = '';
