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.
.

.
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.
.
This package contains headers and library needed to write and compile new
UMView modules. For some simple module examples, you can take a look to the
existing modules (expecially in the um_testmodule directory of the source
tree). |

.
This package contains the UMView controlling daemon and some modules, both
for testing and for real use. Other modules are contained in separate
packages because they depend on additional libraries. |

This package contains a sub-module for umdev. umdev is contained in the main
UMView package and allows virtualization of character and block devices.
umdevtap creates a virtual TUN/TAP interface (i.e. /dev/net/tun). On the
outer side, UMView opens a connection to a VDE switch. |

.
This package contains the old um_lwip module, a gateway to the LWIPv6
user-level networking library (see liblwipv6-2), and a newer one, called
umnetlwipv6. They make possible for processes inside UMView to use virtual
network interfaces that are connected to the external world through a TUN/TAP
device or a VDE switch. |

This package contains (very experimental) modules that allow filesystem
namespace mangling (as hiding some portions of the filesystem, creating COW
subtrees and so on). |
