=== Context Separation === The separation mentioned in the Concepts section requires some modifications to the kernel to allow for the notion of Contexts. The purpose of this "Context" is to hide all processes outside of its scope, and prohibit any unwanted interaction between a process inside the context and a process belonging to another context. This separation requires the extension of some existing data structures in order for them to become aware of contexts and to differentiate between identical uids used in different virtual servers. It also requires the definition of a default context that is used when the host system is booted, and to work around the issues resulting from some false assumptions made by some user-space tools (like pstree) that the init process has to exist and to be running under id '1'. To simplify administration, the Host Context isn't treated any differently than any other context as far as process isolation is concerned. To allow for process overview, a special Spectator context has been defined to peek at all processes at once.
