Exercise 4-2: Kali Linux Unattended Install

1. Minimum requirements: 2GB RAM, 20 GB disk space. You know this by now, RIGHT?
2. This is pretty much a standard install with modified boot parameters. Here are suggested boot parameters:

preseed/url=https://www.kali.training/dojo/preseed.cfg locale=en_US keymap=us hostname=kali domain=local.lan

Note that the locale, keymap, hostname and domain parameters are set on the kernel command line!

Note: The above screenshot is for reference only, and you should use the following URL vs what is in the image: https://www.kali.training/dojo/preseed.cfg

Zen question: "Why can't the fancy preseed thing handle the locale, keymap, hostname and domain parameters?"

Good question. Preseeding parameters depends on the preseed method. If you use a preseed file in the initrd, then you can preseed all parameters even those that are very early in the process. If you use a preseed file from the network or from the ISO image itself, then the preseed gets applied a bit later in the installation process and the early parameters need to be preseeded on the kernel command line.

Alternatively, you could also use the auto=true and priority=critical preseed parameters.

If you didn't know this, step up your game! Pay attention! The auto and priority boot parameters are specifically mentioned in chapter 4.3. Don't think you can skim all the material and slide by. We're keeping an eye on you.
