[ale] PSA: Pay attention to your sector alignment

[James Sumners]

Actually, could start the partition on sector 64 if you really want[1]. The
important thing is that it be a multiple of 4. You might also consider
switching to gdisk[2] instead of fdisk (provided your motherboard is
capable).

personalities. It is not that power corrupts but that it is magnetic to the
corruptible. Such people have a tendency to become drunk on violence, a
condition to which they are quickly addicted."
