Introduction

What is umview-mod-viewfs
umview-mod-viewfs is:
View-OS is a novel approach to the process/kernel interface. The semantics of each system call can be assigned process by process giving the user the right to decide which view of the system each process has to join. Each process can “see” a different file system structure, networking resources, processor, devices. Moreover some of the resources can be provided by the user him/herself, thus these resource can be private to the single process and are not known a priori by the system. Groups of processes can share the same view but this is just an optimization to share management methods.
For more information, see http://wiki.virtualsquare.org
UMView is a user-mode implementation of View-OS. Processes are run with a controlling daemon that captures all the system calls (at present using the ptrace() system call) and uses dynamically loadable modules to change their semantic.
