Now, this doesn't have anything to do with the "prelink" routine that cron
runs?  Prelink changes file sizes and signitures but I don't know if it
designed to hush up tripwire about these changes.

Woah... I just looked at /var/log/prelink.log, and every single file flagged by tripwire is also listed in the log. You may be on to something here, but then my question is, why now? The system's been up and running for a while now (a month at least) and only now does it start affecting them?

A preliminary test just done, shows that when I undo the prelink to one of the changed binaries, it reverts back to the original file size. Redoing the prelinking, and it goes back to the larger size. So maybe that's the answer, it's prelink doing this, and tripwire flagging them accordingly. So then the question still is: why now? Why not a week ago, or a month ago?
