Summary:An alternative approach to building an entire operating system
(OS) separating those parts of the OS that control the basic hardware
resources (the kernel) from those that determine the unique
characteristics of an OS environment, is examined, taking the Mach
kernel as an example. Mach features which support OS emulation are
discussed. In-kernel and out-of-kernel emulation are described. Two
instances of the latter approach, the multithreaded Unix server and the
multiserver Unix, are considered. Related work and Mach availability are
addressed
