It's not /dev he's backing up -- its /home, /usr, and others. GNU tar saves the device and inode numbers from the {,l}stat() call on each file and decides it is a new file if either number changes from run to run. You are correct about /dev -- who'd back it up if it is dynamically created? But that is also not the problem Gene is having.
