Step 5

dd if=/dev/urandom ... is used rather than the equivalent shred,
which is much faster, and also gives a progress report.
Also the following note is less than informative,

I've updated step 5 at the fedora wiki as to how I think it should read:
(I wouldn't include the mention of scrub or wipe from there)

Note I'm quite sure the PRNG within shred is good enough for this operation:
