Abstract: In this paper we show how to extend the functionality of standard operating systems completely at the user level. Our approach works by intercepting selected system calls at the user level, using tracing facilities such as the /proc file system provided by many Unix operating systems. The behavior of some intercepted system calls is then modified to implement new functionality. This approach does not require any re-linking or recompilation of existing applications. In fact, the extensions can... (Update)

...Interposition Agents [17] looked at providing an infrastructure for using interposition as a general mechanism for OS extensibility. Ufo [4] examined the potential for applying this technique as a means of implementing a user level filesystem. Completely in kernel system call...
