Replace Debian install with NixOS on Scaleway

This is based on nixos-infect.

These instructions assume you have x86 scaleway machines that use UEFI and DHCP. You have may have to change /dev/vda15 if your machines are partitioned differently.

Run:

A way to install Alpine Linux on a Scaleway Stardust instance without the use of a rescue image, but by booting into the install image over the network using https://netboot.xyz.

Connect to the serial console, using scw instance server console {uuid} zone={zone}
Reboot the VM into UEFI settings
- either by executing systemctl reboot --firmware on the machine
- or by using scw instance server reboot {uuid} zone={zone} locally and repeatedly mashing the escape key on the serial console
Go to Device Manager -> Network Device List -> the only network device -> HTTP Boot Configuration -> Boot URI

	Just to avoid confusion, I wanted to point out a few things here.

	For reference, all of the info I've gathered below is directly from the documentation found by running the following two lines of code through your Python interpreter:

	>>> from Crypto.Cipher import AES
	>>> help(AES)
	Block Size vs Key Size

	AES has a fixed data block size of 16 bytes (128 bits)
	AES can have a key size of 128, 192, or 256 bits (16, 24, or 32 bytes)
