[Milhouse]

Just giving Milhouse's instructions another go, and when I do the parted commands, setting the partition sizes, I get

Warning: The resulting partition is not properly aligned for best performance

I'm ignoring this so I can keep going, but is it something I should be concerned with?

I've amended my original instructions to correctly align the first partition, I've also added a couple of checks which will confirm if both partitions are correctly aligned.
