That's kind of funny.  It's there for files to "overwrite"!   But maybe you
mean instead something like what happened to me recently.  A new rpm
installed in an old Redhat system actually replaced this device with a
file, and I didn't notice till I rebooted. Booting up, some commands are
outputting to /dev/null while the filesystem is still read-only (ok if a
device, error if a file), causing a boot failure.  Very irritating and took
me a while to resolve.
