30 years of development and continual introduction of new features
build on top of existing ones is considered a very good design. And
FreeBSD is still extensible and growing, despite of its age.
And FreeBSD is not a skyscraper neigther literally, nor metaphorically
- it's more like a spaceship - a very robust one - gives you the means
and tools to save your life in deep space when a threat to your life
appears and there is noone around.
Before even starting talking about design, we should give proper
definition for this concept.
What is good design?
How do we measure one design against an alternative one?
The widespread notion of good desing is related to the ability to
maintain, extent and comprehend easily some complex system.
30 years... You do the math!
I'm not sure you're ready to present a new and revolutionary design
(you should start a new threat on that). It's more like you're in
search of volunteers to your FreeBSD Critisism Project.
Revolutionary design means starting from scratch  - this would be a
huge, tremendous investment of time and efforts(choose a platform, a
language, write a compiler for it, start building a kernel, write
completely new device drivers - Microsoft have its Singularity
Research Project - an operating system written entirely in C#, but
they don't share the tools - the C# compiler and linker they use to
build that system, neighter the code - you can get just a couple of
PowerPoint presentions, an interview, and a short 50 page long paper,
about the features that this system will introduce - on the other hand
you can get all of the FreeBSD source code, tones and tones of
documentation, and hundreds of ready to help you people - FOR FREE).
And there's no guarantee that this new design would last even 5 years.
At some point in time this will probably happen, but it won't be
FreeBSD. FreeBSD is not a vendor - it's an existing and evolving
operating system and a commited community of FreeBSD users. The
emphasis is on evolving.
If we want to stick to FreeBSD, the new design should be evolutionary
one, which is pretty different in concept - we would start from a
familiar code base and would slowly integrate changes (just like the
DragonFly project) into this base, thus creating a new BSD branch of
