+# Bootstrapping
+
+This will help you boostrap a bare host with the help of the 
+[bespoke iso](./iso) live installer.
+
+_Note: nothing prevents you from remotely executing the boostrapping 
+process. See below._
+
+Once your target host has booted into the live iso, you need to partion
+and format your disk according to the [official manual][manual].
+
+## Mount partitions
+
+Then properly mount the formatted partitions at `/mnt`, so that you can
+install your system to those new partitions.
+
+Mount `nixos` partition to `/mnt` and — for UEFI — `boot` 
+partition to `/mnt/boot`:
+
+```console
+$ mount /dev/disk/by-label/nixos /mnt
+$ mkdir -p /mnt/boot && mount /dev/disk/by-label/boot /mnt/boot # UEFI only
+$ swapon /dev/$your_swap_partition
+```
+
+## Install
+
+Install using the `flk` wrapper baked into the iso off of a copy of devos 
+from the time the iso was built:
+
+```console
+$ cd /iso/devos
+$ nix develop
+$ flk install NixOS --impure # use same host as above
+```
+
+<!-- TODO: find out why --impure is necesary / PRs welcome! -->
+
+## Notes of interest
+
+### Remote access to the live installer
+
+The iso live installer comes preconfigured with a network configuration
+which announces it's hostname via [MulticastDNS][mDNS] as `hostname.local`, 
+that is `NixOS.local` in the [iso example](./iso).
+
+In the rare case that [MulticastDNS][mDNS] is not availabe or turned off
+in your network, there is a static link-local IPv6 address configured to
+`fe80::47`(mnemonic from the letter's position in the english alphabet:
+`n=14 i=9 x=24; 47 = n+i+x`).
+
+Provided that you have added your public key to the authorized keys of the
+`root` user _(hint: [`deploy-rs`](../integrations/deploy) needs passwordless
+sudo access)_:
+
+```nix
+{ ... }:
+{
+  users.users.root.openssh.authorizedKeys.keyFiles = [
+    ../secrets/path/to/key.pub
+  ];
+}
+```
+
+You can then ssh into the live installer through one of the 
+following options:
+
+```console
+ssh root@NixOS.local
+
+ssh root@fe80::47%eno1  # where eno1 is your network interface on which you are linked to the target
+```
+
+_Note: the [static link-local IPv6 address][staticLLA] and [MulticastDNS][mDNS] is only
+configured on the live installer. If you wish to enable [MulticastDNS][mDNS]
+for your environment, you ought to configure that in a regular [profile](../../profiles)._
+
+### EUI-64 LLA & Host Identity
+
+The iso's IPv6 Link Local Address (LLA) is configured with a static 64-bit Extended
+Unique Identifiers (EUI-64) that is derived from the host interface's Message
+Authentication Code (MAC) address.
+
+After a little while (a few seconds), you can remotely discover this unique and host
+specific address over [NDP][NDP] for example with:
+
+```console
+ip -6 neigh show # also shows fe80::47
+```
+
+***This LLA is stable for the host, unless you need to swap that particular network card.*** 
+Under this reservation, though, you may use this EUI-64 to wire up a specific
+(cryptographic) host identity.
