rpm has had md5sums for a good, long time. Yet, when someone asks me 'why did my box break', its amazing how many times asking rpm to verify the md5sums finds ps, ls, etc. modified. Most attackers I've had to clean up after don't have a CLUE as to what they're doing.

If I have md5sums of each file, I know which files are damaged. That's quite different than knowing "something in xserver-xfree86 changed."
