Installation of Arch Linux on RAID with the BTRFS filesystem

Base system installation

Mount USB drive containing instalation scripts in the 'arch_install' directory

Assuming here that /dev/sda is USB stick containing arch linux installation and /dev/sdb contains our configuration scripts

mkdir /store
mount /dev/sdb1 /store
cd /store/arch_install

Run all the scripts that handle disk management

The script accepts "sata" and "nvme" as valid inputs

example:

sh 00_setup_scripts.sh sata

Download system files

./06_pacstrap.sh

Create fstab and mdadm config, remove resolv.conf

./07_pre_chroot.sh

Chroot into the new filesystem

cd
umount /store
arch-chroot /mnt
mount /dev/sdb1 /mnt
cd /mnt/arch_install

Setup timezone, language, ntworking, create ramdrive, update sudoers config

./10_post_chroot.sh

Install grub

./11_install_grub.sh

Setup root password

passwd

Instal KDE Plasma

./12_install_gui.sh

Setup snapper and make initial snapshot

./13_setup_snapper.sh

Exit chroot environment and reboot

exit
reboot

Optional steps

Add user

useradd -mG wheel herman
passwd herman

snapper -c root create —description 'Initial install, users'

Install nvidia drives (from local user in gnome)

pacman -S nvidia
echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf
mkdir -p /etc/pacman.d/hooks

vi /etc/pacman.d/hooks/nvidia.hook
