It runs in #GNOME or in a headless #server environment and is easy to configure a local apt-mirror repository, link persistent #VM images, customize package lists, and so on. I've been daily-driving this on my laptops/desktops/servers for 2 years.
A nice perk of using a configuration like this is that it eliminates the need to upgrade your system and be concerned about migration issues. To upgrade, simply re-flash the boot drive to the newer OS version and use the same script to configure it.
