Run Alpine Linux from RAM as a desktop OS

The goal is to have a system on an external USB drive that loads the entire OS to RAM and runs from there. The OS will include a full a graphical desktop (XFCE in this example). Home directories and other persistent storage will be on filesystems on internal laptop block devices.

Caution

Rule #1: Any changes to the OS or packages added by apk add must be followed by lbu commit -d to save the changes to the OS partition. You will lose work by forgetting to call lbu commit -d. See below for examples.

# a custom handler can we support both formats to go through __setstate__
