Introduction

Linux is a desk-top and server system and with some provisions an excellent embedded OS/RTOS. The basic concepts of embedded systems as quite a few development kits show is to down scale a desk-top Linux system to something that will kind of fit on flash [9], DOC [7], Compact-flash [8] or a floppy or... But the concept stays a desk-top concept !

In the past there have been fairly few dedicated embedded tools under development - notably busybox was a clear approach to the size of user-land for embedded systems. The problem clearly is that there were neither clear standards available for developing such a user-land nor were the guiding concepts adopted, even more so for device drivers and interfacing to specialized hardware.
