From 2014-07-16 Linux Mint ("Debian") AIO DVD is part of the Linux AIO http://linuxaio.net.
Our plan was to bring some of the major Linux distributions (Ubuntu and flavors, Linux Mint, Linux Mint “Debian”, Debian Live) with different desktop environments on one ISO file that can be burnt on one DVD or USB flash drive. Every one of them can be used as Live system, with no need of installation on hard drive, or can be eventually installed on computer for full system experience.
Linux AIO Linux Mint ("Debian") is not official project of Linux Mint. These are unofficial ISOs which are include original files from Linux Mint ("Debian") editions ISOs and they are made for personal purposes.
