OpenSolaris Code Released
njcoder writes "C|net's news.com.com has reported that Sun Microsystems is releasing parts of the OpenSolaris code today licensed under the OSI-approved CDDL . The release consistes of over 5 million lines of code for the base system OS/Net (kernel and networking). OpenSolaris is based on Solaris 10, the current version of Sun's Unix Operating System. Back in January, Sun released the code for DTrace, a dynamic tracing tool for analyzing and debugging kernel and userland events. DTrace is one of the big features in Solaris 10. Some other highlights include the GRUB bootloader, SMF (Service Management Facility) which replaces init.d scripts, it starts up processes in parallel for faster boots (7 second boot on a dual opteron workstation I think that was the setup) as well as providing features for automatically restarting. OpenSolaris provides support for x86/x86-64 processors as well as Sparc. The Blastware guys are working on Polaris which is an OpenSolaris port to PowerPC. Sun has been working on opening Solaris for over a year now. The OpenSolaris project started with a pilot group of Sun and non-Sun users. During the pilot program a lot of info including screenshots could be found on various OpenSolaris member blogs. (My favorite is Ben Rockwood's blog). Teamware is the source code management system Sun uses for Solaris and OpenSolaris. Which was designed by Larry McVoy (now of BitKeeper) while he was at sun. No word yet on if Teamware will be available for OpenSolaris developers or not. Sun also uses CollabNet for it's Open Source project websites so that might be a possibility as well."
heh... bet that gets taken out right quick. http://cvs.opensolaris.org/source/xref/usr/src/cmd /volmgt/vold/dev_rmscsi.c
thanks for the tip.
perl -e 'foreach(values %SIG){$_="IGNORE";}while(){}'
Some Sun guys are doing a port to Xen. This'll give you near-native performance for Solaris apps, along with the comprehensive device support provided by a Linux (or NetBSD) "domain 0" (host virtual machine).
_ xen_summit (it seems to be down right now).

Ckeck out Blastwave.org http://www.blastwave.org/ for some torrents, apps, guides, and other goodies.
Additionally, SunFreeware http://www.sunfreeware.com/ is another great site for getting applications.
Justing reading the stuff that is released, however, is a joy.
Am I part of the core demographic for Swedish Fish?
That answer depends on who you are. If you're a system administrator Predictive Self-Healing is going to raise the reliability of your systems and make management scads easier; SMF makes configuring the system a snap and lets you identify problems quickly and easily; Zones lets you partition the system without the management overhead of a bazillion OS instances; DTrace lets you understand everything that's happening on your system -- and who's responsible for the latest crap-up; Solaris Process Rights improve security and administrative overhead by splitting up the traditional binary notion of the super user. If you're a developer, you'll love DTrace -- I can't imagine developing with out it; the p-tools, truss(1) and mdb(1) are also great. If you're an end-user, well, Solaris's gnome sucks as much as anyone's gnome -- go use Mac OS.
For Linux and FreeBSD and common packages/ports on opteron and ultrasparc there's still 64 bit cleanliness issues, and there's BSD issues running on Ultrasparc III and above chips (as in, can't do it). FreeBSD is still trying to implement fine grained SMP spinlocks which don't sieze up under heavy load & to get fine grained locks into tcp stack. Solaris builds backward compatibiity into libraries that Linux dosen't have, which is why when installing proprietary app binaries there's all kinds of neat patching and relinking that needs to be done (for example, installing Oracle on Sun is a breeze, but on Linux takes some care as to java and various library versions, and for another example enterprise SAN software such as veritas or Hitachi drivers only works with certain kernels). Solaris has the definitave and latest/greatest versions many services such as RPC and NFS (linux has some issues there)
Believe it or not, there are numerous legal issues that Sun has to work through in order to ensure code that is open sourced doesn't get anyone in trouble.
Be patient. They're working on it. Or would you rather they open source some code they don't have the right to, and get people who see that code into trouble?
There is still alot of work to be done, but it is a huge first step.
For more, take a look at the roadmap at

Be kind. There are too many mean people out there already.
DTrace lets us examine just about anything, with minimal impact on the system. It's way cool, and other OSes have nothing that is close (for details covering the Linux Trace Toolkit (LTT), DProbes, K42 and Kerninst see the USENIX paper.
DTrace solves disk I/O by PID, network activity by PID, elapsed and on-cpu times for syscalls, libcalls and user funcs, and much more.
DTrace is great if you are a programmer with a little kernel knowledge, but if not you may find the DTraceToolkit helpful - it is a collection of ready-to-roll scripts.
