Helper script to install Arch Linux with ZFSBootMenu from within a running Arch Linux live CD ISO image
|
|
|
|
# Prep
|
|
|
|
We expect minimal prep on your end. Please make sure that before execution the following conditions are met.
|
|
|
|
- Arch Linux live CD ISO image sees exactly one partition with partition type code `BF00` ("Solaris root")
|
|
- Arch Linux live CD ISO image sees exactly one partition with partition type code `EF00` ("EFI system partition")
|
|
- No ZFS zpool exists
|
|
|
|
The script will create a single ZFS zpool `zpool` on the `BF00` partition with dataset child `zpool/root` which itself has one child `zpool/root/archlinux`, that's where Arch Linux gets installed. Parallel to `zpool/root` it'll create `zpool/data` with a `zpool/data/home` child dataset that gets mounted at `/home`.
|
|
|
|
The script will use the `EF00` partition to install a ZFSBootMenu EFI executable if `efibootmgr` says that no such `ZFSBootMenu` entry exists. If ZFSBootMenu gets added to the EFI partition it'll become primary boot option.
|
|
|
|
# How to run this?
|
|
|
|
- Boot an Arch Linux live CD ISO image
|
|
- Run:
|
|
```
|
|
export SCRIPT_URL='https://quico.space/quico-os-setup/arch-zbm/raw/branch/main/setup.sh'
|
|
curl -s "${SCRIPT_URL}" | bash
|
|
```
|
|
During execution the script will call itself when it changes into its `chroot`, that's why we `export SCRIPT_URL`. Feel free to update `"${SCRIPT_URL}"` with whatever branch or revision you want to use from [quico.space/quico-os-setup/arch-zbm](https://quico.space/quico-os-setup/arch-zbm). Typically `.../branch/main/setup.sh` as shown above is what you want.
|
|
|
|
# Steps
|
|
|
|
The scripts takes the following installation steps.
|
|
|
|
1. Install ZFS tools and kernel module with [github.com/eoli3n/archiso-zfs](https://github.com/eoli3n/archiso-zfs)
|
|
1. Create one encrypted ZFS zpool on top of `BF00` partition, password `password`
|
|
1. Create dataset for Arch Linux and `/home`
|
|
1. Install Arch Linux into pool
|
|
1. Add ZFSBootMenu to `EF00` partition if it doesn't exist already
|
|
1. Exit into Arch Linux live CD ISO image shell for you to `reboot` and frolick
|

# Flavor choices
|
|
|
|
We make the following opinionated flavor choices. Feel free to change them to your liking.
|
|
|
|
* Arch Linux locale is set to `en_US.UTF-8`
|
|
* Keymap is set `de-latin1`
|
|
* Consult `/etc/vconsole.conf`
|
|
* Change `zfs set org.zfsbootmenu:commandline=...`
|
|
* No X.Org Server, Wayland compositors or other GUI elements get installed
|
|
|
|
# Post-run manual steps
|
|
|
|
After installation you're goig to want to at least touch these points in your new Arch Linux install:
|
|
|
|
* Hostname: Installation chose a pseudo-randomly generated 8-character string with `pwgen`
|
|
* Unprivileged user accounts: The OS was installed only with a `root` account
|
|
* Passwords
|
|
* ZFS: The password for all datasets underneath `zpool` is `password`.
|
|
* Local `root` account: The local `root` account's password is `password`.
|
|
* Arch User Repository (AUR) helper: We installed [paru](https://github.com/Morganamilo/paru) as our AUR helper, we installed from GitHub via `makepkg -si`. You may want to replace that by an AUR native installation e.g. by doing `paru paru`.
