OpenSolaris Indiana Released
Lally Singh writes "The Linux-friendly OpenSolaris Indiana has been released! A new, modern package manager and all the goodies of Solaris: ZFS, DTrace, SMF, and Xen on a LiveCD that was designed for Linux users. 'Why use the OpenSolaris OS you ask? It's pretty simple, you'll find it full of unique features like the new Image Packaging System (IPS), ZFS as the default filesystem, DTrace enabled packages for extreme observability and performance tuning, and many many more. We think you'll be quite happy to came by to take a look!'"
They employ sexy-code formatting monkeys. The solaris kernel is a hack of a lot simpler to understand than the Linux kernel - I hege this on my comparison of the sources a while back.
There is still no mighty IOKit killer on the horizon tho... Apple (and libkern, the cpp runtine) wins.

With ZFS you can smash a hard drive and keep the system running:

I've played around with ZFS, it's very cool. I mean very very cool.
It's a crying shame the licensing issues keep it from being ported to Linux as part of the kernel
I came to the datacenter drunk with a fake ID, don't you want to be just like me?
I'm installing it right now. It looks like a copy of Ubuntu. It has a LiveCD, standard GNOME desktop, and an online package manager (called pkg).
Don't take that as criticism. Cloning Ubuntu is probably the best design decision an OS team can make these days.
Personally, I don't care whether it's Solaris or Ubuntu or *BSD underneath it all, so long as it supports my hardware and runs my applications.
A slashdotter who didn't build his own computer is like a Jedi who didn't build his own lightsaber.
Not bloody likely. Even a "clean-room" interpretation of ZFS will run afoul of Sun's patents, and those patents are only licensed under the CDDL.
Jesus is coming -- look busy!
Then you don't really understand the file system. Seriously, I think this is the BEST reason to look at Solaris .. ZFS is amazing: snapshots; Z-RAID; Zetabyte file ssytem; prevention of bit rot ...
... you don't care about your photos, docs and music???
They have also forcibly crashed it over a million time and it has never lost data even once. Try doing that with your home PC.
And what
is that ZFS, despite all its goodness, lacks some incredibly basic features compared to 99% of the hardware and software RAID and LVM systems out there. You can't grow (please pay attention here) a ZFS pool except by adding similarly-redundant vdevs, and there is no way to remove a vdev from a pool, unlike LVM2.
So. Got a 4-drive RAID-Z2 array, and you want to add more space by buying another drive to add in to your 5-bay hot-swap cage? You're shit outta luck. If you have a zpool with a vdev that consists of a pair of mirrored drives, you CAN add another vdev of two drives, then another, etc. You also CAN replace the drives in a vdev with larger drives. That's kind of half-okay, but still not on par with RAID cards of a DECADE ago. Even Linux's MD can grow RAID5/6 across more devices!
Someone suggested the ability to grow redundant pools by single devices, and the reaction amongst solaris ZFS developers (!!!) was "now why would you want to do that?", and then when THAT was explained, "well shucks, I wonder how they do that" (they = almost every hardware and software RAID solution on the planet.)
Absolutely astounding that a Solaris filesystem developer would not be able to at least guess as to how a RAID5 array would be re-striped to add a new drive.
Far as I know, they've been working on the grow capability for more than a year and we have yet to see it.
Please help metamoderate.
No this is Debian.
Sorry, I'm calling you on your B.S. Sun fanboy.
ZFS is *not* ready for production.
I'm a working Solaris admin. I can point to several ZFS raidz arrays that have had to be recovered from tape due to ZFS bugs losing & corrupting data.
This is clearly a case of ZFS marketing outstripping ZFS reality. They have implemented all the cool features, but have dropped the ball on robustness.
Do a sunsolve search for ZFS panics or ZFS corruption. There are a half-dozen major bugs that are still un-resolved, and won't be until Sol10u6 - if then. [u5 was just released in the last week or so]
