Hi Chris

The last line is essentially the result of the fact that ext2 is the
same as ext3 on most accounts. A pure ext2 driver will indeed be able
to read and write and do anything on ext3. However, there are some
improvements on ext3, the journaling function is the most known one
(and the only one I know). The pure ext2 driver will not be able to
use journaling. So if your system crashes while writing, the data will
be seriously damaged.
Also the pure ext2 driver will not be able to restore an ext3 system
that has crashed, while a true ext3 driver can (if the crash happend
with a true ext3 driver, and some luck of course).
