MINIX3 now has support for live update and rerandomization of its system services. These features are based on LLVM bitcode compilation and instrumentation in combination with various run-time extensions. Live update and rerandomization support is currently fully functional, although still in an experimental state, not enabled by default, and available for x86 only. This document describes the basic idea, provides instructions on how to enable and use the functionality, provides more in-depth information for developers, and lists open issues and further reading material.

A very detailed look at this piece of MINIX3 functionality.
