Hi http://www.muktware.com/n/19/2011/846/tim-burke-ext4-not-going-anywhere-any-time-soon "Red Hat engineers work actively to develop these features in the upstream kernel, work both with the Fedora community and others to integrate them for early adopters and then evaluate when they are robust enough for enterprise users." "*//*File systems are very long lived in the field since users tend to maintain them for years and years. In many cases, enterprise users have external storage so the storage will survive several generations of servers. That means that ext4 is not going anywhere any time soon! That said, Red Hat is an active contributor to the btrfs project and we are actively working on getting some of the key inhibitors for wide btrfs deployment finished with the upstream community" Rahul -- marketing mailing list marketing@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/marketing
