Hello!
I always found it quite annoying that each Linux installer re-creates a few hundred thousand files upon each installation, because it takes a hell lot of time.
Solution 1: put a system partition image onto the installer DVD that includes the complete installation. Upon installation, copy it to the target partition und resize it to fit the partition size.
Solution 2: mount the system partition image from DVD in read-only mode. The installation process (up to the point where the user can start working) would not copy any files -- except for /boot,/etc. When the system is started after the installation has been finished (by mounting the image via loopback device(s)), the files in the system partition image on the DVD would be copied to the disk in the background.
I tend to prefer the first solution because it is a great simplification and would speed up installation up to quite some factor.
