Why oh why

I want to develop some scripts for things like Chrx, Chromebrew, MrChromebox scripts etc and I don't want to register a new SSH key to my account every time I need to powerwash or use recovery on one of my Chromebooks because I messed it up. I already use my Yubikey for GPG/FIDO/U2F/SSH on all the other systems I develop on, and I only needed the SSH portion to work for this particular use case. I also didn't want to deal with using Crouton or Crostini since that requires additional downloads and more configuration and complexity.

Challenges

Since the Crosh userland doesn't have scdaemon or pcscd for talking to the smart card, I had to come up with another way to access the Yubikey and make the SSH key available. I ended up trying a few different things to make it work, but overall the solution ended up being brilliantly straightforward. Originally I tried using Chromebrew to install one of the smartcard access/manager packages, but the dependency chain ended up pulling in Gnome keyring and a

About

This gist will show how to setup Raspbian Stretch as a headless Bluetooth A2DP audio sink. This will allow your phone, laptop or other Bluetooth device to play audio wirelessly through a Rasperry Pi.

Motivation

A quick search will turn up a plethora of tutorials on setting up A2DP on the Raspberry Pi. However, I felt this gist was necessary because this solution is:

• Automatic & Headless - Once setup, the system is entirely automatic. No user iteration is required to pair, connect or start playback. Therefore the Raspberry Pi can be run headless.
• Simple - This solution has few dependencies, readily available packages and minimal configuration.
• Up to date - As of December 2017. Written for Raspbian Stretch & Bluez 5.43
