Fd Linux is a mini floppy distribution of Linux set to fit on 1 floppy disk (kernel and root fs are combined). The sole purpose of this floppy distribution is to provide new Linux users with low-end machines (such as a 386) a very useful set of networking related binaries that can be easily accessed at any time, and which can be used in almost any networked environment (libraries, colleges, offices, small home LANs, dorm rooms, etc.).
