+# Debian unattended install
+
+> **ATTENTION:** this repo is focused on my thesis work so expect some mess and low generalization.
+
+## Usage
+
+Get help:
+
+```sh
+./regeniso-sid.sh -h
+```
+
+### Examples:
+
+> **Note:** `preseed/kube.cfg` at the moment works only with the _netinst_ image. The reason is that with the _netinst-minimal_ I should manually install some kernel modules (`cdrom` for example) and at the moment I don't know how to do this.
+
+Generate a _netinst_ with a _kube_ preseed:
+
+```sh
+./regeniso-sid.sh preseed/kube.cfg netinst stable amd64 auto "bluetooth.blacklist=yes bnep.blacklist=yes"
+```
+
+## Initialize the VM
+
+Create a VM and launch the unattended install.
+
+Minimal requirements:
+
++ 2 Cores
++ 3GB RAM (8GB for a decent experience)
+
+Once the unattended installation finished successfully we should prepare the environment inside the VM.
+
+Launch this script:
+
+```sh
+/srv/custom/main.sh
+```
+
+Once it concluded successfully shut down the VM.
+
+Use the image of the first VM as a base and create 3 different linked volumes:
+
+```sh
+qemu-img create -f qcow2 -b baseImage.qcow2 deltaImage.qcow2
+```
+
+Create 3 clones of the base VM and associate at each one a delta image. Beware that each VM **_must_** have a different MAC address.
+
+Launch the 3 VM clones and in one of them (usually the first) login and then install Rancher:
+
+Login without polluting the _known hosts_ file:
+
+```sh
+ssh virtualuser@ipAddress -o "StrictHostKeyChecking=no" -o "UserKnownHostsFile=/dev/null"
+```
+
+And then launch this to install Rancher:
+```sh
+docker run -d --restart=unless-stopped -p 80:80 -p 443:443 --privileged rancher/rancher
+```
