I'm often asked the relationship between the various Solaris named products that Sun provides. Here is my view on them:
OpenSolaris is a SOURCE code project at opensolaris.org from which a number of actual products may be derived including:
- Portions of Solaris 10
- Solaris Express and SX Dev. Edition
- xVM Server
- Project Indiana
Solaris Nevada is the portion of Open Solaris community code that includes only the kernel (OS and Networking consolidations). Running uname on this build indicates SunOS 5.11.
Solaris Express Community Edition is Sun's binary release for
OpenSolaris developers (code named "Nevada"). It is built from the
latest OpenSolaris source and additional technology that has not been
published in the OpenSolaris source base. This release is unsupported.
Developers can build the OpenSolaris source by using this release as
the base system. It is updated every other Friday.
Solaris Express Developers Edition, includes Solaris Express Community Edition along with the development tools (Netbeans, Studio etc) in a single installation to simplify life for developers. The Developer Edition is released every three to four months and replaces the Solaris Express monthly release.
Project Indiana is currently in preview edition two. The OpenSolaris Developer Preview is the first milestone of Project
Indiana. It is a single CD combined live/install image: a core
operating system, kernel, system libraries, a desktop environment and a
package management system. It is not a final release and is intended
for developers to try, test, and provide feedback.
Solaris 10 is our enterprise ready, supported version of Solaris. It is updated less frequently and provdes a stable platform for deployment of long term applications.
They are ALL free to download use in a production environment. If you need support for Solaris 10 you can choose from a variety of Solaris 10 subscriptions on Sun or non-Sun hardware (Sparc, Intel or AMD based).
Don't you mean "free to use"? I believe Sun only charges if you want support, otherwise it is free to use with no encumberance.

Thanks to Brian Cameron of Sun for providing this answer.....
The best way to do this is to modify the GDM Init script so that it
launches a dialog. If you launch the dialog with "&" then the dialog
will display with the login screen. If you don't launch with "&", then
the user will need to exit the dialog (perhaps by hitting a confirmation
button) before the login screen will display.

Bharat,
Thanks for reading my blog and asking questions.
OpenSolaris is essentially the development train for the next long term supported version of Solaris. While maintaining complete binary compatibility with Solaris 10,,OpenSolaris introduces a wide variety of new features including:
New Image Packaging system
ZFS improvements
Network Virtualization and quality of service
Xen-based server virtualization on X86 HW
Improved user interface and tools
Network Auto-magic configuration
Improved device driver and platform support
Improved power management
In kernel CIFS support
New Automated installer
Default ZFS root
ZFS based Live upgrade
I/O improvements (ISCSI, SCSI target, etc)
Improved IPv6 and IPSEC capabilities
Improved patching methodologies
and more.
Additional improvements will be coming in 2010.
