Sun CEO Says ZFS Will Be 'the File System' for OSX
Fjan11 writes "Sun's Jonathan Schwartz has announced that Apple will be making ZFS 'the file system' in Mac OS 10.5 Leopard. It's possible that Leopard's Time Machine feature will require ZFS to run, because ZFS has back-up and snapshots build right in to the filesystem as well as a host of other features. 'Rumors of Apple's interest in ZFS began in April 2006, when an OpenSolaris mailing list revealed that Apple had contacted Sun regarding porting ZFS to OS 10. The file system later began making appearances in Leopard builds. ZFS has a long list of improvements over Apple's current file system, Journaled HFS+.'"
Jobs is probably not happy about his thunder being stolen right before for the June 11th keynote
I strongly doubt he didn't know about it. This is Jonathan Schwartz, not a OS X rumors blogger. At any rate, ZFS in OS X is Sun's thunder; Time Machine is Apple's thunder, and that's already announced. How many OS X users (other than slashdot readers) will care in the slightest about the underlying filesystem? What they care about are the features, like Time Machine, that it enables.
I think Slashdot would benefit from adopting some of K5's approach to story submissions. The Firehose is a great start, but instead of simply saying yes or no, users should be able to give feedback to the submitter. The summary for this article is a great example. The submitter typed "build" instead of "built," resulting in an annoying distraction in an otherwise concise description of the story.
Newspapers have Copy Editors (at least they used to; most seem not-too-bothered by spelling these days). It would be nice if interested Firehose users were given the opportunity to help make sure the summary was fit for publication before it hits the front page.
I guess this should have been a journal entry, but it seemed like an opportune time to bring this up.
I don't care why you're posting AC
Apple is "well known" for massive backwards compatibility updates... except they aren't... They always handle transitions over a couple of versions, intelligently bringing people along. They swapped processor architectures twice and each time brought people along with emulators, in the Intel case it wasn't faster than the fasted G5 machines, but those of us upgrading 3+ year old machines (Powerbook G4 1Ghz -> Macbook Pro in my case) found our PPC apps running faster and Intel code flying.
We all expected the Intel migration to happen with 10.5, they shocked us when they did it off the 10.4 base.
While they did abandon Mac OS to move to OS X, they provided a migration strategy (Carbon) and a compatibility layer (Classic). Classic support shipped with 10.0/10.1, 10.2, and was supported in 10.3 if you already had it, as well as 10.4 I think, but they kept classic for around 5 years, which gave everyone time to migrate to Carbon. Its unfortunate that there is no long-term Classic via Rosetta just from a classic application point of view, but they didn't leave anyone in the lurch.
I expect 10.5 to introduce this OS, which will be useful for new installs, or for external drive arrays, especially for the Video market, but I wouldn't expect it to be the default. OS X has supported a Unix filed system, but defaulted to HFS+, because HFS+ was compatible with Mac OS, so you could dual-boot OS 9 and OS X for a good 2 years on new hardware to maintain compatibility. If they hadn't done that, they would have lost the Pro-Audio and Pro-Video markets that took a few years to get native OS X applications.
Getting it in the wild and for professionals would help that market, while not breaking ANYONE's compatibility. Sometime in 10.5's lifetime they may ship new computers with it, or they may wait for 10.6 in two years. But giving everyone two years is plenty of time to get utilities and applications compatible with the new file system.
The flashy consumer features are touted for the OS, but the underlying architecture has always followed a 2-cycle release. If you've used OS X Server for 10.2/10.3/10.4, you'd notice that they introduced stuff in one version with limited exposed functionality (with the rest via the Unix layer), enhanced the functionality in the next rev, and polished thereafter.
The Apple Mail Server -> Cyrus migration was someone poorly handled, but mostly because AMS was garbage. But the 10.4 Mail tools are night and day beyond the 10.3 ones.
They are actually far more careful than people give them credit for.
The different is, they don't keep backward compatibility as a long-term goal, they do a two-stage migration, giving people 2-4 years to transition.
