I think you mean "Red Hat Linux 7.1 to 7.2"... distro version numbers
are only meaningful if you identify the distro you're referring to.

tune2fs -j /dev/hda1

(or whatever the partition's device is)

If you do this while the partition is mounted, you'll see a file called
.journal in the root directory of the partition. If you don't want this,
do it while the partition is unmounted. (It doesn't really matter either
way -- it doesn't hurt anything for it to be visible.)

Yes, as long as your kernel does. Any 2.4 kernel should be okay.

Well, there you go.
