ABSTRACT:
Embodiments of the present invention are directed to a method and apparatus for restricted run-time environment with dynamic user context. In one embodiment, a user interacts with the computer system through a restricted run-time environment. When the user begins using the computer system at a local machine (i.e., a client), a user context is dynamically created at the local machine. Then, a user interface is initiated in the run-time environment which is isolated from the local machine's system files. In one embodiment, the user interface and all actions resulting from interaction through the interface take place in the isolated run-time environment. In one embodiment, the isolated run-time environment contains its own set of system files that the user may need to access. In one embodiment, the local machine is running the Unix™ operating system. A user interacts with the system through an interface running from the chroot directory.
