Linux While Ext4 was originally merged in 2.6.19, it was marked as a development filesystem. It has been a long time coming but as planned, Ext4dev has been renamed to Ext4 in 2.6.28 to indicate its level of maturity and paving the way for production level deployments. Ext4 filesystem developer Ted Tso also endorsed Btrfs as a multi-vendor, next generation filesystem and along with the interest from Andrew Morton, Btrfs is planned to be merged before 2.6.29 is released. It will follow a similar development process to Ext4 and be initially marked as development only.

BTRFS, Reiser4 without the stigma?

Seems like BTRFS is much more along the lines of a modern filesystem like ZFS or Reiser4.

If BTRFS is to be merged in 2.6.29, would it be stable enough for desktop use then? Though not suitable for critical production use.

It won't be ready for the desktop. It is still in development.

Oracle, Red Hat, IBM and Novell want something that has even more features than ZFS (when combined with a logical volume manager).
But it will take until 2010 until you will see it in production. Maybe the next RHEL will ship it. That is just a guess though.

Hmm .... i don't think you will see brtfs in 2010 in real production. The development of a totally new filesystem is a longer process. Just think about the time ext needed to get production ready. Or the fact that reiserfs is still suspected to loose files when loaded with millions of files. brtfs it's not like ext[1-4], which is a evolutionary development, it's something completely new.

BTW: The whole brtfs development looks like a "Oh, heck, we need something similar to ZFS ...". I hope they make a better job with brtfs as with systemtap. And i do not believe that the ZFS development will stop ... in 2010 ZFS will have more features, too.

Well according to the topic above, it'll be merged into 2.6.29. So it must be ready in some shape or form to be merged into the mainstream kernel. The question is whether it'll be EXPERIMENTAL or an initial release?

I think 2.6.29 will be ready sooner than 2010.

Doubt it.
I'd venture and guess that RHEL will continue using ext3 by default, but will offer ext4 is a certain command line option is used during installation/boot.

If indeed btrfs will be released within 2010, I -may- end up in RHEL 7.
