Linux Mint 12 LXDE
According to its website, “this is the first release of Linux Mint using Hybrid ISO images.
Traditionally, tools such as ‘Startup Disk Creator’ or ‘UNetbootin’ were needed to install Linux Mint via USB. With hybrid images, you can simply use the “dd” command or a graphical frontend to make a bootable USB stick with no efforts which acts exactly like a liveDVD”.
