A newly created ext4 partition created with e2fsprogs 1.41.x will have
all of the various goodies enabled.  Note that some of what "goodies"
are enabled are controlled by the mke2fs.conf file, which some
distribution packages treat as a config file, so you need to make sure
it is appropriately updated when you update e2fsprogs.
