Problem with data=journal on root file system.

I am using RedHat 7.2 w/ kernel 2.4.7-10.  My / filesystem is configured
as ext3.  I want to change it to use data=journaled instead of ordered.
If I mount it from a boot floppy, it mounts fine.  (mount /dev/hda2 /mnt
-t ext3 -o data=journal).  I have attempted to find the correct
procedure to start it up as journaled from grub to no avail.  I have
created a new initrd image that works fine with data=ordered.  I see
where one procedure is to use lilo -R linux rw rootflags=journal=update.
(I'm not using Lilo)  I'm confused about the read&write aspect as
well
as why they used journal=update instead of data=journal.  This
filesystem was created new with this system, so I should not have to
upgrade it.  Thanks.
