Running the initial command `lotus-seal-worker run` gave an error about `--address` being a required parameter.
After setting that to `127.0.0.1:2345` the miner started to freak out and sectors broke as the mining process locked up.
It seems like in the mean time the sealing work has already been moved into the `lotus-storage-miner` and thus doesn't need to run alongside the miner.
Changed the docs to what I think is correct now - but please check, I could be horribly wrong :)
