My install guide for arch.

Getting started

Changing keymap to swedish

loadkeys sv-latin1   

Connect to wifi

wifi-menu

Partitioning

Create one 500MB EFI-partition (+500M) and allocate the rest for the root-partition.

fdisk /dev/sda

Change type of the first partition to 1 (EFI) and the second one to 31 (LVM). Format /dev/sda1 to vfat.

mkfs.vfat -F32 /dev/sda1

Encryption and LVM

Encrypt the LVM by using the following:

cryptsetup --cipher aes-xts-plain64 --key-size 512 --hash sha512 luksFormat /dev/sda2

Open the crypt

cryptsetup luksOpen /dev/sda2 arch

Then setup the partitions inside.

pvcreate /dev/mapper/arch  
vgcreate vol /dev/mapper/arch  
lvcreate --size 8G vol --name swap  
lvcreate -l +100%FREE vol --name root  

And format them

mkfs.f2fs /dev/mapper/vol-root  
mkswap /dev/mapper/vol-swap

Mount partitions

Mount them all

mount /dev/mapper/vol-root /mnt  
mkdir /mnt/boot  
mount /dev/sda1 /mnt/boot  
swapon /dev/mapper/vol-swap  

Bootstrap the system, generate fstab and then chroot into it

Install the choosen packagesgroups. More can be added i.e gnome.

pacstrap /mnt base base-devel

Generate /etc/fstab

genfstab -U /mnt >> /mnt/etc/fstab

Chroot in to the system

arch-chroot /mnt

Now that we are in our new environment. Lets install some extra packages

pacman -S zsh networkmanager intel-ucode

Set up some basic things

Setup timezone and enable NTP

timedatectl set-timezone Europe/Stockholm
ln -sf /usr/share/zoneinfo/Europe/Stockholm /etc/localtime
timedatectl set-ntp True

Edit locale.gen and then generate locales

nano /etc/locale.gen  
locale-gen

Set hostname

echo  myfunnycomputername > /etc/hostname

Set up userstuff

Create a useraccount

useradd -m -G wheel -s /bin/zsh myhaxxorusername

Set a password

passwd samehaxxorusername

Configure sudo by opening the configration file and uncommenting the wheel-option

visudo

And lastly, disable the root-user

passwwd -l root

Generate a ramdisk

vi /etc/mkinitcpio.conf

And make sure it contains the following

MODULES="i915 dm_mod dm_crypt ext4 aes_x86_64 sha256 sha512"  
BINARIES=()  
FILES=""  
HOOKS="base systemd block autodetect modconf keyboard sd-vconsole sd-encrypt sd-lvm2 filesystems"  

Then generate it

mkinitcpio -p linux

Install bootloader

Install systemd-boot by running:

bootctl --path=/boot install

Time to identify all the necessary uuid:s

lsblk -o name,uuid  

NAME                                          UUID  
sda                                             
├─sda1                                        85FD-5ABB  
└─sda2                                        8cbdf380-fd94-4972-b19c-b25a7d14245a <-- for rd.luks.uuid  
  └─luks-8cbdf380-fd94-4972-b19c-b25a7d14245a l82dSB-TMw0-81MM-DLVW-85Xg-UZIX-M2fgq6  
    ├─vol-swap                                aee08b20-885f-4c38-9bfa-eb2f4ee19887  
    └─vol-root                                8f5c623f-f043-41c3-8b68-29e47c563c67 <-- for root=UUID  
  

And create a new file for the bootloader to use.

vi /boot/loader/entries/arch.conf

And make sure it contains this with need adjustments. The first rd.luks.uuid should be the uuid for the /dev/sda2

title	Arch  
linux	/vmlinuz-linux  
initrd	/intel-ucode.img  
initrd	/initramfs-linux.img  
options rd.luks.uuid=[uuid for /dev/sda2] rd.lvm.lv=arch/root rd.lvm.lv=arch/swap rd.luks.options=discard root=UUID=[uuid for encrypted root] ro quiet loglevel=3 vt.global_cursor_default=0 rd.systemd.show_status=0 rd.udev.log-priority=3 i915.fastboot=1  

Reboot

Just reboot!
