deploy-enc-arch.sh

This script will allow a fast deployment of an Arch Linux server with:

Features

NTP enabled
LVM on LUKS with:
- An optional swap partition depending on installed RAM when the script is run
- An ext4 root partition using the remaining of the disk
Pacman mirrolist with french servers
Europe/Paris as timezone
fr_FR.UTF-8 and en_US.UTF-8 locales
A fr-latin1 keymap
Systemd resolved as DNS resolver
Systemd networkd with DHCP on eth0 (with interface renaming disabled)
A default privileged local admin
Grub + dropbear SSH to unlock server remotely on port 222
OpenSSH with root login and password authentication disabled

Usage

After booting on archiso, copy config and deploy.sh on the host to deploy. Edit config and replace ADMIN_NAME, PASSPHRASE and AUTHORIZED_KEY if required.

Then run bash deploy.sh -h HOSTNAME -d /path/to/device or bash deploy.sh -h HOSTNAME -d /path/to/device -s if you don't want a swap partition.

The script will detect if archiso was started in legacy or UEFI mode. If UEFI is available, Arch Linux will be installed on a UEFI partition.

Limitations

As I use this script to deploy my Arch Linux hosts before running Ansible playbooks, this script doesn't allow the creation of multiple users nor the addition of multiple SSH keys.
