"Thus even if you used MINIX 1 when you were in college, try MINIX 3; you'll be surprised. It is a minimal but functional UNIX system with X, bash, pdksh, zsh, cc, gcc, perl, python, awk, emacs, vi, pine, ssh, ftp, the GNU tools and over 400 other programs. It is all based on a tiny microkernel and is available right now.
"So **PLEASE** no more comments like 'If Tanenbaum thinks microkernels are so great, why doesn't he write an OS based on one?' He did. (Actually, one of his students and two of his programmers did). It is definitely not as complete or mature as Linux or BSD yet, but it clearly demonstrates that implementing a reliable, self-healing, multiserver UNIX clone in user space based on a small, easy-to-understand microkernel is doable..."
