In this whitepaper, Marco Pantaleoni of Linuxcare Italia provides an overview of Etlinux, an embedded Linux distribution developed by the Italian company, PROSA (subsequently acquired by Linuxcare). Pantaleoni writes . . .

“. . . That which is described above is the panorama within which the creation of Etlinux is set. Etlinux is a project brought to fruition by Prosa (acquired by Linuxcare, and now Linuxcare Italia), a firm that developed and supported only Open Source solutions, with the goal of demonstrating the utility of Linux on systems of modest power.”

“At the moment, to run Etlinux, all that is necessary are: 386SX processor, 2 megs of ram, and 2 megs of disk space (and both normal hard drives and the more compact flash disks or DiskOnChip will work). In this configuration a Tcl interpreter, a small mail server, and an equally small web server are all included.”

“An embedded system has special needs, very different from those of a desktop system. The development of Etlinux reflects these needs, and it is informative to examine the solutions utilized. The availability of source code proves to be quite useful also from the student's point of view.”
