The advantages of simplifying system installation files are obvious: 1) greatly shortens the installation time of OS; 2) saves a lot of disk space occupied by system partition; 3) makes the system run faster; 4) there is no need to manually remove unwanted/unused files one by one after installing the system (otherwise, that's not only extremely inefficient, but also error-prone, and the these files can not be removed completely. So it's better not to install them at all). Besides, integrating drivers, patches, software and other resources into the system installation package can greatly reduce the time and effort spent on driver update, patch update, software installation and other aspects for a newly installed system.
