Arch Installer

A simple installer for Arch Linux

Originally started on it back in 2018 and has been changing ever since. I've been primarily using it when building VMs with Packer

Pre-requisite:

• A new bare metal or virtual machine
• Booted an Arch ISO
• Internet access (can be avoided with f.ex preloading a USB with the installer)

Usage:

1. When the ISO has been booted run the following commands:

   cd /tmp
   wget https://github.com/husjon/arch_installer/archive/refs/tags/v0.2.0.tar.gz
   tar xfzv v0.2.0.tar.gz
   cd arch_installer-v0.2.0

2. Copy _template.sh in host-variables and make any changes you see fit.
3. When done, run the following command, replacing <HOSTNAME> with the name of the file you copied. The .sh extension should be omitted.

   ./arch-install.sh <HOSTNAME> INSTALL

4. The installer will now run through lall the steps.

What the installer does.

1. Loads in global-variables and a host-variables based on the input arguments.
2. Updates the mirror (if set).
3. Formats and partitions the disk defined in the host-variable.
4. Runs pacstrap with the packages defined in both global-variables and the host-variable
5. When the pacstrap finishes it uses arch-chroot to run the finalizing steps
   1. Set timezone
   2. Sets and generates locale and keymap
   3. Sets the hostname
   4. Creates a new initramfs
   5. Sets up the bootloader
   6. Sets a default password of the root user
   7. Enables systemd-networkd and systemd-resolved
   8. Enables sshd

After all this, the only requires step is to reboot the machine and shortly after it should be booting into the new installation.
