- A webcast with OTN's Rick Ramsey at 10:30 AM (Pacific) on Tuesday
- A session at the "Unconference" at Hotel Parc 55 at 3 PM on Tuesday
I'm planning to be generally hanging around the conference on Monday. @dave_miner on Twitter will be one way to find me if you like.
If your main interest is Solaris, I should note that my friend Deirdre has kindly posted a schedule of the Solaris Unconference Sessions at Oracle Open World 2010.

First up is the addition of iSCSI support to Automated Installation (or AI). You can now specify an iSCSI target for installation in the AI manifest. It'll work on both SPARC and x86, provided you have firmware that can support iSCSI boot; on SPARC you'll need a very recent OBP patch to enable this support. Official docs are in the works, but the design document should have enough info to piece it together if you're interested.
Next is the bootable AI image, which allows use of AI in a number of additional scenarios. Probably the most generally interesting one is that you can now install OpenSolaris on SPARC without setting up an AI server first, by using the default AI manifest that's included on the ISO image. One caveat is that the default manifest installs from the release repository; due to ZFS version changes between 2009.06 and present, this results in an installation that won't boot. You'll want to make a copy of the default manifest and change the main url for the ai_pkg_repo_default_authority element to point to http://pkg.opensolaris.org/dev and put it at a URL that you can supply to the AI client once it boots. Alok's mail and blog entry have more details.
Building on bootable AI, we've extended the Distribution Constructor (or DC) with a project known as Virtual Machine Constructor (VMC). Succinctly, it extends DC to construct a pre-built virtual machine image that can be imported into hypervisors that support OVF 1.0, such as VirtualBox or VMware. Glenn's mail notes a few limitations that will be addressed in the next few builds. Anyone interested in building virtualization-heavy infrastructures should find this quite useful.
Finally, one more barrier to adding OpenSolaris on x86 to a system that's multi-booted with other OS's has fallen with the addition of extended partition support to both the live CD GUI installer and Automated Installation. You can now install OpenSolaris into a logical partition carved from the extended partition. Jean's mail has some brief notes on how to use this new feature. I should also note at this point that a couple of builds ago the parted command and GParted GUI were added to the live CD, so the more complex preparations sometimes needed to free up space for OpenSolaris can now be done directly from the CD.
I'd like to thank my team for all the hard work that went into all of the above; they accomplished all of it with precious little help from me, as I spent most of the past three months either traveling around talking to literally hundreds of customers or working on architecture and design tasks. Speaking of those, the review of the installer architecture is open, and I've also just this week posted the first draft design for AI service management improvements.
What's next? Well, that will be the topic of my next post in early January. It's time for a vacation!

[Phoronix] Fedora 13 May Support Btrfs System Rollbacks
Nice to see Fedora planning to add features we in OpenSolaris take for granted! I'd certainly be more inclined to use Fedora for the occasional times I need Linux if this came in, as I've suffered in the past from RPM disasters. It does look like they've got some design work to do yet on the file system organization, as for rollbacks like this it's critical to ensure that system software state, operational data such as logs and audit trails, and user state are separated. Though this is something we haven't yet completed satisfactorily in OpenSolaris, either. We mostly do well on user state since home directories are outside the boot environment section of a root pool, but separating the invariant parts of /var (logs, mail queues) out from the variant parts is a problem we still need to resolve.

Unfortunately the set of supported platforms for the supported reader, Adobe Digital Editions, is not too friendly for those of us on open-source platforms. My best suggestion, though I haven't tried it yet, is to put it on a copy of Windows in VirtualBox.

Two things going on that I thought worth mentioning:
- The OpenSolaris update to build 121 was released a couple of days ago. We hope recent quality problems are behind us so that updates will be back on the regular cadence.
- As part of our continuing efforts to educate the community about OpenSolaris installation, the BigAdmin guys asked me to spend a week answering questions as part of their XPert series, starting today. If you have a burning question you haven't seen answered, fire away. I must also say that Rick is (or at least was, we've both aged a bit) a better basketball player than he admits

Thanks to all of you who came to our various talks. If you're interested in the slides, they should all be available from the OpenSolaris @ C1 wiki.

Jerry and Nick are also doing deep dive sessions on Tuesday about their respective specialties: zones and HA clustering. I'm planning to kick back and relax a bit that day :-)
Since this is the first time the three of us have been in the same place, there's also a signing session for the book being planned; as soon as that's scheduled, we'll get it posted.
Oh, and it's important to mention that Tuesday's deep dives are free if you use the promotion code OSDDT when you register for them; the easiest way is to just click on the widget below. I hope to see you there!

OpenSolaris Live USB Creator (Windows/.NET) (PID0.ORG DevZone)
If you do try it out, I recommend build 111, which we just released a couple of days ago. It's getting pretty close to the end of development for the 2009.06 release, so we'd love some additional testing.
Anyone up for doing a similar tool for Linux (and adding a GUI to the OpenSolaris tool)?

Now we just need to include copies of OpenSolaris Bible with each one for the perfect bundle ;-)

Since I was traveling and missed posting a note about build 109, it's probably a good idea to mention one of the changes that appeared there and continues with 110: going to only a single, global CD image. This had been our intention all along since starting the distribution, but it depended on the LZMA (de)compression support in lofi; we got that done before the 2008.05 release, but its performance was judged to be too slow at the time so we made the expedient decision to ship two different CD's, with the primary CD using the better-performing gzip algorithm. We figured we'd come back to that issue once we got the LZMA code integrated into the ON gate, which just finally happened a couple of weeks ago.
In the meantime, OpenSolaris community member (and super-contributor!) Juergen Keil took an interest in the performance issue, and found the primary culprit in the lofi code, which was repeated decompression of the same data (see bug 1119 for the discussion if you're curious). The performance improvement is, we believe, good enough to return to just the single image for the next release. But we would like data to confirm that, so if you do an install from the build 109 or 110 CD, please send info on the time it took (you can just send the installation log if you like; it's found at /var/sadm/system/logs/install_log after installation) and the basic stats on your hardware (processor speed and number of cores, memory size) to firstname.lastname@example.org, we'd appreciate it.
