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.
