logic involved

The Nexenta Project is taking an interesting approach to assemble an operating system: they take the kernel from OpenSolaris and the userland from Ubuntu.

So they get:

• the stability, security and advanced system management and development tools from OpenSolaris (DTrace, ZFS, …),
• the package repository from Debian,
• and the easy-to-use desktop from Ubuntu.

If you are looking at an interesting weekend project, trying it in VMWare might be just what you are looking for!
