This simple root file system produces a fully functional system. On the ARM/XScale board on which this was tested, the size of this small root file system was about 1.7MB. It is interesting to note that more than 80 percent of that size is contained within the C library itself. If you need to reduce its size for your embedded system, you might want to investigate the Library Optimizer Tool at http://libraryopt.sourceforge.net/.
