FYI.

The primary purpose of this release is to > make the source available to interested parties. No installation kit > is included. > > Lites is a 4.4 BSD Lite based server and an emulation library > that provide free unix functionality to a Mach based system. > > Lites provides binary compatibility with 4.4 BSD, NetBSD (0.8, 0.9, > and 1.0), FreeBSD (1.1.5 and 2.0), 386BSD, UX (4.3BSD) and Linux on > the i386 platform. It has also been ported to the pc532, PA-RISC, and > preliminarily to the R3000 and Alpha. Lites works with Mach 3.0, > Mach 4, and RTMach. > > The recommended user platforms are NetBSD 1.0 and FreeBSD 2.0. Linux > file system support is not included in this release. > > Lites was written by Johannes Helander at Helsinki University of > Technology based on 4.4 BSD Lite from University of California and > code written by the CMU Mach group. Several people have contributed to > the effort, including Ian Dall, Mike Hibler, Jeff Law, Bryan Ford, > Jukka Virtanen, Mary Thompson, Sampo Kellomaki, John Dyson, Csizmazia > Balazs, Chris Maeda, and Timo Rinne. > > Special care has been put into keeping the code legally clean. Each > piece of code that has been added to Lites has been carefully > examined. There is no Net2 or 4.3 BSD code in Lites. > > > Lites consists of a multithreaded single server that handles multiple > system calls from any process, file paging, etc. and an emulation > library that provides applications with an environment that looks like > the system the application expects. The emulator is a completely new > implementation and removes most of the security problems associated > with earlier emulators (protection against resource attacks requires > kernel support). > > Lites has been self hosting for several months. Its current > performance is 6% lower than that of NetBSD 1.0 as measured by > building gcc within the exact same machine and environment. Many > obvious optimizations especially in the field of i/o have not yet > been made. > > Lites is available from the following locations: > Europe: ftp://ftp.funet.fi/pub/mach/lites/ > USA: ftp://mach.cs.cmu.edu/afs/cs.cmu.edu/project/mach/public/src/lites/ > > > For more information refer to the Lites home page > http://www.cs.hut.fi/lites.html > > I have also made my Master's thesis available in postscript form under > the same URL. It covers some aspects of Lites. > > Johannes > -- Ollivier ROBERT -=- The daemon is FREE! -=- roberto@FreeBSD.ORG FreeBSD keltia 2.1.0-Development #14: Sun Feb 26 16:31:40 MET 1995
