I found this line in the root crontab on our 3B2/600, which is now
running R3.2.2.  This smells a lot like a kludge fix/workaround to
some sort of bug, but I've never heard of it before: it doesn't
look like it can possibly be doing anything useful.

0 0 * * * dd if=/dev/mem of=/dev/null 2>/dev/null

My questions are:
1. Why is it there?
2. Does it still need to be there?  (Or is it there to fix a
   problem in a previous release which is now fixed right and
   doesn't need this?)
