Arch Linux installation (lvm2)

After my power went out here while I was on an extended vacation, I realized the folly in having a completely encrypted drive that could only be unlocked via a locally entered password. Ideally GRUB and the kernel could be configured to probe the network to develop a fingerprint of its devices, and unlock automatically without any further keys if all devices are present. Otherwise, unlock via entered password. This is a task for another day.

My current task is to install a plain, unencrypted Arch Linux installation to my old workstation (lithium). I have a new SSD, and I want to document the process of installation (mainly so I can follow it again). It is adapted from my Encrypted Disk instructions.
