These scripts allow you to have a wireguard connection in your initrd. Make sure you have wireguard installed on your system and a busybox which supports ip, nslookup. If it does not work, change the copy_exec line for busybox in the hook and replace it with a better one. It reads /etc/wireguard/initramdisk.conf and expects at least one comment specifying all ip addresses like so: # Address = 1.2.3.4/12. Tested on Ubuntu 19.10.
