This change is a response to recent customer demand. Novell is seeing increasing numbers of customers who prefer ext3 to ReiserFS, and our choice of default for SUSE® Linux Enterprise 11 reflects this. Today, ext3 and ReiserFS v3 are mostly on par: ext3 has very recently gained some scalability enhancements (h-trees) and online expansion support (in SUSE Linux Enterprise Server 10). Furthermore, ext3 now features more than three years of journaling hardening, which makes it competitive with ReiserFS v3. OCFS2 is a parallel cluster file system designed for specific workloads, but it is unlikely that it will have root/boot support by SUSE Linux Enterprise 11. Finally, Novell is following the development of ext4, and expects it to become a solid nextgeneration enterprise file system.
