My personal ArchLinux/NixOS installer

Usage

• start the live environment
• curl --proto '=https' -sSfO https://raw.githubusercontent.com/as3ii/as3ii-installer/master/setup-base.sh to download the script
• chmod +x setup-base.sh to make it executable
• ./setup-base.sh to execute it

If you want, you can pass some parameters:

• -d /dev/sdX select device to be wiped and formatted
• -e /mnt/boot/efi select partition or mountpoint to use as EFI
• -b /mnt/boot select partition or mountpoint to use as Boot
• -r /mnt select partition or mountpoint to use as Root
• -k uk select keyboard layout
• -c enable root partition encryption with luks2 Use -e, -b and -r if you have manually created (and optionally formatted and mounted) the needed partitions. In this case -d option will be ignored if present. If -e, -b, -r and -d are not set, then this script will try to install the system on the default folders (the ones specified above)

What setup-base.sh does

This script will wipe the given device, these are the partitions that will be created:

1: boot partition
            FS: vfat
            Size: 500M (499M if efi is not detected)
            Mount Point: /boot
2: luks2 encrypted partition (when enabled)
            Mount Point: /dev/mapper/cryptroot
    2.1: root partition
            FS: btrfs
            Size: rest of the disk
            Hash: xxhash
            Mount Point: none
            Mount Options: autodefrag,space_cache=v2,noatime,compress=zstd:2
                           'discard=async' will be added when ssd is detected
            Subvolumes:
                Subolume         : Mount Point       : specific options
                @                : /
                @snapshot        : /snapshot
                @home            : /home
                @opt             : /opt
                @root            : /root
                @swap            : /swap             : nocow
                @tmp             : /tmp              : nocow
                @usr_local       : /usr/local
                @var_cache       : /var/cache        : nocow
                @var_log         : /var/log
                @var_tmp         : /var/tmp          : nocow

Then it will create swapfile, update archlinux-keyring, update pacman's mirrors list, install base system (base linux linux-firmware btrfs-progs man-db man-pages neovim git grub efibootmgr), generate fstab and crypttab, configure mkinitcpio, configure and install grub, and setting some base things such as keymap and locale.

To Do:

• add more checks
• add more options for more customizability (in progress)
• add zram
• more verbose output
• grub installation and configuration
• rEFInd installation and configuration
• make luks's cryptography optional
• /boot encryption
• snapshot after installation
• post-base-install script download & launch
