No, that (journalling) and some extra options like directory indexing
is the difference between ext3 and ext2.
Ext4 is completely rewritten, finally adds extends and a LOT of other
fs capabilities (like larger then 8 TB partitions) to ext3.
I'll need to dig around one of these days to really grasp the available
filesystems. Aside from support for larger than 8TB partitions, do you
still consider ext4 the new go-to system?
