Upgrading to v1.5.5f

[tmpinsnty]

So I'm working on updated my v1.5.1 sites and first bump I hit is with this: define('DIR_FS_ROOT', realpath(__DIR__ . '/../') . DIRECTORY_SEPARATOR);

I need help coming up with the best way to change this to suit my needs.

right now this points to : /var/www/clients/client0/web15/web/mystore/includes/classes/class.base.php

I have hundreds of cloned sites that read a lot of the same files from one central directory.

I need this to read: require(/var/www/clients/client0/web15/web/src/includes/classes/class.base.php). 'src' is one central directory. what is the best way to define DIR_FS_ROOT to reflect just this directory.

Just something like this? define('DIR_FS_ROOT', 'src/')?

__DIR__ is automatically-detected by PHP.

Why are you trying to tell it that it's located in a directory where it is not?

So when it reads this code:
require (DIR_FS_ROOT . 'includes/classes/class.base.php');
require (DIR_FS_ROOT . 'includes/classes/class.notifier.php');

It reads a file that does not exist. All the classes files are only in src directory.

This creates a path to this: var/www/clients/client0/web15/web/myclonedsite/includes/classes/class.base.php)
I need it to look for the appropriate file here: var/www/clients/client0/web15/web/src/includes/classes/class.base.php)

An out-of-the-box Zen Cart store doesn't have a DIR_FS_ROOT definition; it does have a DIR_FS_CATALOG, though.

Not the actual store but the zc_install folder for me to update does have this constant.
