========================
you forgot cosmic rays, nuclear war and zombie apocalypse, among other
failure modes. *NOTHING* is capable of protecting against everything; a
good solution will most always have pitfalls; as a
sysadmin/engineer/manager one has to either accept the pitfalls or find a
more acceptable solution, which usually means different pitfalls. that
doesn't mean a given solution is useless.
