Ext4 is no longer in beta as of Kernel 2.6.28.x Ext4 requires that you use e2fsprogs v1.41.x or higher For other accurate and pertinent information, check out: http://kernelnewbies.org/Ext4 You *CAN* convert ext3 to ext4 AND use extents. Read how at the link above. And I am using ext4 for everything except /boot, and yes it *feels* faster, and though I don't do the benchmarking thing, I like the feeling. Know the truth :) Check the link above, and check kernel.org, the more official sources.
