If anyone is bored and wants to run through an Alpine Linux headless install on a Raspberry Pi (or x86_64), I updated the wiki page I made for it and provided a link there to an overlay file that's already built.
The basic steps are to:
- download the appropriate RPi Alpine tarball
- format an sd card and mount it
- untar the Alpine files onto the sd card
- copy the headless.apkovl.tar.gz file to the root of the sd card (do not untar)
- create a wifi.txt in the root of the sd card (or skip this if using ethernet)
- insert card and boot, pi should dhcp itself onto the network
- ssh as root with no password to finish setup
