"We had used the Nexenta Core Platform 2 operating
system that combines the OpenSolaris kernel with a GNU/Ubuntu
user-land to that of the same Ubuntu package set but with the Linux
kernel. Testing was done with both 32-bit and 64-bit Ubuntu server
installations.
"For our testing we were using the RC2 build of Nexenta Core
Platform 2 (NCP2), which is based upon OpenSolaris Build 104+ but
with Debian and Ubuntu packages based upon the 8.04 LTS "Hardy
Heron" distribution. For those that have never used the Nexenta OS,
its tagline is the "Power of OpenSolaris with the usability of
Linux!" This OpenSolaris distribution even uses Debian's apt-get
for package management. The Nexenta Core Platform is equivalent to
an Ubuntu server installation, but there is a StormOS project
underway to create a Xfce4-based desktop version of the Nexenta
Core Platform 2."
