Good article... but this shouldn't be a surprise... if you Google for moblin btrfs you'll find articles from September last year already ;-)

We've been using btrfs in our builds ever since, and the MeeGo code release a while ago also obviously was using btrfs. It's been very stable for us in all our testing since August/September of last year, and the feature set is very attractive obviously (as is the data integrity)

Mobile Operating systems are cloud based devices. You sync amost 100% of the user content: apps, pictures, music, contacts, email.... or even better view those on demand. So I don't think any mobile OS developers care that much about on-disk formats =) prime example apple loves to whipe your iAnything anytime it likes =) cause storing stuff on their devices isn't even supported without getting it into your iTunes library when you go to charge it ;-)

Errrr, I don't know about iPhones, but N900 very much support putting things on the device, and I certainly use the storage for apps, music and pictures without syncing.

Horseshit.

I've carried an n800 around for over a year now, and *precisely the fact that it has two 16GB capable SD slots* is the reason I wouldn't replace it with an n810, much less an n900.

The Cloud is *greatly* overrated; I give it about 5 years to implode under the accumulated weight of the failings inherent in it which the people flacking it never mention. :-)

Upstream (Chris Mason) already needs to, and committed, things to be compatible. (At least forwards compatible, eg he can add things but will support the older formats). Linus really asked him to do this already before

I'm glad to hear that. I like btrfs a lot but I thought the decision to go with it by default was a bit risky. Now I think it's the best option in the long run... good luck with that.

I've been running btrfs on laptops as /home since January 2009 without incident so far, though I'm not what you'd call a big disk space user.

Me too, I was using Btrfs for the whole system except for /boot because grub doesn't know how to handle it. I didn't hit any problem with it but after a good while I decided to go back with ext4 because boot times was slower with Btrfs.

But won't we need O_DIRECT for the new phone Oracle's releasing?

From the people who brought you Oracle*Mail, which took the world by storm, comes Oracle*Phone. (Requires constant always-on connection to your Oracle Enterprise Server, licensing fees only $6b per year per CPU, expiry of database logging complete content of all calls ever made extra. Comes with free whole-phone-network crash bugs. Oracle is not responsible for any side effects should you use this device in an unsupported manner, e.g. by using the device to communicate with any non-Oracle*Phone device, by plugging the device into the charger, or by holding the device above waist level while in use.)

I can't wait.

;)

(Oracle, at least pre-Sun-merger: pretty good backend software. Frontend software horrifically awful. Should they ever produce a mobile phone I suspect my silly litany above would be an *understatement*.)
