Don't emit extra output at init invocation
Many users have complained that they're database is corrupt because
they tried to start the database and it refuses to do so, and at
the same time emitting a message with the word "corrupt". this is
just plain wrong and confusing, so I'm removing it.

Anyway init scripts should not emit any extra messages apart from
start OK / failed.
