Bluetooth Pairing one device on Dual Boot of Windows & Linux - Stop having to Pair Devices

You may have experienced when dual booting that you need to re-pair your bluetooth devices (ie., Headphones, mouse, keyboard, etc) this usually happens because you have already paired the device with another operating system using the same bluetooth adapter when dual booting (either Linux or Windows).

Some devices cannot handle multiple pairings associated with the same MAC address (ie., bluetooth adapter). As per suggested on the ArchWiki you can fix this by re-pairing the device each time, but there's actually another solution to not do so each time you choose to use your device on a different OS.

How can we accomplish this?

Easy, just pair the device on a OS and copy the bluetooth keys generated to the other OS so our device doesn't notice the difference.

KISS instructions on how stow works and how to easily set it up

Create a git repo directly in your home folder, .g. ~/dotfiles

In this directory, you create a folder with a "package name" and in it the exact folder structure this app has it's config files in your home folder.

Let's take i3 for example, which has its config file in ~/.config/i3/config

Move this file into ~/dotfiles/i3/.config/i3/config. Now you can git add and git commit it, like usual.

Advice

Before starting I highly suggest you create a new directory on your /home/user directory with an appropiate name for this task like rpi0alarm so you can change directory to /home/user/rpi0alarm and go through the following steps.

As I wrote this guide after collecting info from different sources (listed at the end) be mindful of your current path and the commands you are running to not damage your current installation on the host computer you are creating the SD Card.
