I don't want to replace Linux.

In fact, I probably couldn't have built Open Nexus OS without Linux. I use Linux every day, and for general-purpose computing it is an extraordinary piece of software.

So whenever I say that I am building a different operating system, I expect the obvious question:

Why didn't you just modify Linux until it did what you wanted?

That question is actually what led me to build this.

Why this post exists​

If you come from a university lab or a research institute, you usually don’t ask, “Does it boot?” You ask the questions that matter long-term:

• What is the model?
• What is the contract surface?
• How do you validate changes without destabilizing the system?
• Where does performance come from in a microkernel world?
• What does “secure” mean operationally, not rhetorically?

This is the current answer for Open Nexus OS.
