Linux is used by itself, or with small other programs, in some appliances. These small software systems are a far cry from the GNU/Linux system. Users do not install them on PCs, for instance, and would find them rather disappointing. It is useful to say that these appliances run just Linux, to show how different those small platforms are from GNU/Linux.
