install guide

very wip arch guide

set keyboard layout:
```
loadkeys sv-latin1
```
set system clock:
```
timedatectl set-ntp true
```

optional: connect to wifi if no ethernet:

nmcli d wifi connect <ssid> password <pass>

find and partition disk:

(WARNING: WILL NUKE DRIVE!!!!!!!!!)

fdisk -l
fdisk /dev/<disk>

g                         # create efi partition table
n [enter] [enter] +1G     # create boot part
n [enter] [enter] [enter] # create root part
t 1 1                     # set type of first to "EFI"
t 2 23                    # set type of second to "Linux Root"
w                         # apply changes

format partitions:
```
mkfs.fat -F32 /dev/<disk>1
mkfs.btrfs --csum xxhash /dev/<disk>2
```
xxhash checksum is very fast and very much good enough for detecting accidental errors.
mount root:
- no compression:
```
mount -o defaults,lazytime /dev/<disk>2 /mnt
```
  lazytime stores access times in memory and only commits periodically to reduce drive wear.
- light zstd compression
```
mount -o defaults,lazytime,compress=zstd:1 /dev/<disk>2 /mnt
```
  simple and almost transparent compression for reducing size of smaller files.

mount boot:

mount -o defaults,noatime --mkdir /dev/<disk>1 /mnt/efi

don't need access time on the boot partition.

bootstrap base packages:

pacstrap /mnt base linux-zen linux-firmware nano networkmanager man-db man-pages texinfo openssh sudo

generate fstab from current mounts:
```
genfstab -U /mnt >> /mnt/etc/fstab
```
change root into target system:
```
arch-chroot /mnt
```

set timezone and sync hardware clock:

ln -sf /usr/share/zoneinfo/<region>/<city> /etc/localtime
hwclock --systohc

open up /etc/locale.gen and uncomment en_US.UTF-8 UTF-8 plus any other wanted languages. then we can generate em:
```
locale-gen
```
set lang variables by putting the following in /etc/locale.conf:
```
LANG=en_US.UTF-8
LANGUAGE=en_US.UTF-8
LC_ALL=en_US.UTF-8
```
set keyboard layout for cli in /etc/vconsole.conf:
```
KEYMAP=sv-latin1
```
set hostname in /etc/hostname (just an example, can be almost whatever):
```
arch
```
optional: set root password
```
passwd
```

open up /etc/mkinitcpio.conf, comment out any existing hooks and replace with the following ones instead:

#HOOKS=(...)
HOOKS=(systemd autodetect microcode modconf kms keyboard sd-vconsole block filesystems fsck)

enable efi instead of initramfs:
```
cp /etc/mkinitcpio.d/linux-zen.preset /etc/mkinitcpio.d/linux-zen.preset.bak
nano /etc/mkinitcpio.d/linux-zen.preset
```
comment out default_image=... and fallback_image=.... uncomment default_uki=... and fallback_uki=....
configure your kernel parameters in /etc/kernel/cmdline (very basic setup):
```
rw zswap.enabled=0
```
install systemd-boot and generate boot files:
```
bootctl install
mkinitcpio -P
```
enable NetworkManager on boot:
```
systemctl enable NetworkManager
```
optional: enable ssh server:
```
systemctl enable sshd
```
disable remote root login in /etc/ssh/sshd_config:
```
PermitRootLogin no
```
optional: enable sudoers (wheel) group:
```
groupadd wheel
EDITOR=nano visudo
```
uncomment %wheel ALL=(ALL:ALL) ALL.
optional: create a user account:
- if using sudo, also add sudoers group:
```
useradd -m -G wheel -s /bin/bash <username>
```
- if not using sudo:
```
useradd -m -s /bin/bash <username>
```
change password:
```
passwd <username>
```
exit and reboot:
```
exit
reboot
```
