According to Sean Michael Kerner from InternetNews.com, the upcoming Red Hat Enterprise Linux 7 operating system will have support for the Btrfs filesystem.
The Vice-President of Linux Engineering at Red Hat, Tim Burke, talked with Sean Michael Kerner, explaining him that Btrfs has been implemented and marked as experimental in the recently released Red Hat Enterprise Linux 6.3 release, and the next major version, RHEL 7, will have full support for the Btrfs filesystem.
Moreover, Sean Michael Kerner also talked with Wim Coekaerts, vice president of Linux Engineering at Oracle, who said that Oracle Linux would also have built-in support for the Btrfs filesystem.
Well, we can only hope that more upcoming Linux distributions will adopt the Btrfs filesystem, including Fedora and Ubuntu.
