A bunch of files for enabling Wifi in Debian initramfs

Introduction

If you have encryted root partition, you can unlock your root partition over the network using dropbear-initramfs and/or mandos-client. However Debian does not seem to provide a turnkey package that allow you to use Wifi at the initramfs stage. There doesn't seem to be that many tutorials around telling you how to do it. I decided to create this repository to help everyone.

Installation

1. You need to add kernel module of your Wifi device to /etc/initramfs-tools/modules. For a lot of Intel devices (including Intel Corporation AC 1550i Wireless), it is iwlwifi and iwlmvm.
2. You need to create wpa_supplicant.conf. You can create one by using wpa_supplicant.conf.example as a template.
3. Execute install.sh

To uninstall, run uninstall.sh.

Testing

This has been tested on the following systems:

• Lenovo IdeaPad Duet 3
