# Install ARCH Linux with UEFI
# The official installation guide (https://wiki.archlinux.org/index.php/Installation_Guide) contains a more verbose description.

# Download the archiso image from https://www.archlinux.org/
# Copy to a usb-drive
dd if=archlinux.img of=/dev/sdX bs=16M && sync # on linux

# Boot from the usb. If the usb fails to boot, make sure that secure boot is disabled in the BIOS configuration.

# Set finnish keymap
loadkeys fi

# This assumes a wifi only system...
wifi-menu

# Create partitions
cgdisk /dev/sda
1 512MB EFI partition # Hex code ef00 ;sda1
2 100% size partiton # (to be encrypted) Hex code 8300 ;sda2

# Create EFI partition
mkfs.vfat -F32 /dev/sda1

# Create filesystem on  root partition
mkfs.ext4 /dev/sda2

# Create swapfile
fallocate -l 4G /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile

# Mount the new system
mount /dev/sda2 /mnt # /mnt is the installed system
mkdir /mnt/boot
mount /dev/sda1 /mnt/boot

# Install the system also includes stuff needed for starting wifi when first booting into the newly installed system
# Unless nvim and zsh are desired these can be removed from the command. Dialog is needed by wifi-menu
pacstrap /mnt base base-devel zsh nvim git sudo networkmanager dialog wifi-menu wpa_supplicant wireless_tools gnome-keyring

# 'install' fstab
genfstab -pU /mnt >> /mnt/etc/fstab

# Make /tmp a ramdisk (add the following line to /mnt/etc/fstab)
tmpfs	/tmp	tmpfs	defaults,noatime,mode=1777	0	0

# Add swapfile to fstab
/swapfile none swap defaults 0 0

# Change relatime on all non-boot partitions to noatime (reduces wear if using an SSD)

# Enter the new system
