No, but if you plan to use geli to encrypt data that will end up on the
slice it may be a useful thing to:
a) keep a backup copy of the data in its unencrypted form
b) overwrite the entire partition with random bytes (increased entropy
means that it is harder to 'attack' the final encrypted data stream
when geli starts writing over parts of the encrypted slice)
c) attach the randomized partition with geli
d) newfs the xxx.eli device
