Minix 3

Minix 3 is a small, Unix-like operating system released under the BSD-3-Clause license, built by Andrew S. Tanenbaum and publicly announced on October 24, 2005 as a major step beyond the earlier Minix 1.x and 2.0 releases rather than a simple update to them. Its central design goal is fault tolerance: a microkernel architecture keeps device drivers and system servers running as separate user-mode processes rather than inside the kernel itself, so the system can detect a fault, restart the failed component on the fly and keep the rest of the system running with no user intervention. Minix 3 is aimed mainly at embedded systems and education, making its self-healing, isolated-component design a practical demonstration of microkernel principles.
