If I can somehow change the default path to something more readable (via a plugin or a new feature), I won't be needing this anyway. So, I'll look into that, first. Thanks for all your help, till.
ISPConfig uses symlinks for that. Using symlinks is much better in my opinion then using the names in the paths, so you dont have to change the path in all your php scripts if the name of xyz cahnges and the symlinks provide perfect names on the shell to navigate easily.
