"Much as it is with community Linux releases such as
Ubuntu, Debian, Fedora or OpenSUSE, OpenSolaris 2009.06 is an
evolutionary, rather than a revolutionary improvement over the
initial 2008.05 build. All the major open source packages have been
refreshed, as it is to be expected, and for the most part,
OpenSolaris provides a comparable user experience to most Linux
"As with the previous release, OpenSolaris 2009.06 is delivered
as a live CD image, so you can boot and use the operating system
from a CD without having to actually install it on your system, as
it is with Linux distributions like Ubuntu. For the most part,
installing OpenSolaris is just like installing Ubuntu -- boot the
system with a CD, and from the default desktop, click on the
"Install OpenSolaris" icon, which launches a wizard based install.
After installation, the OS boots from a GRUB-based bootloader, just
like Ubuntu Linux."
