# Installation *** A lot of the information for the installation below were obtained from, {% embed url="" %} Arch Linux wiki for most of the information {% endembed %} {% embed url="" %} This guide showed the correct way to mount btrfs and generate fstab for it {% endembed %} {% embed url="" %} Contains some good information that I could not figure out easily from wiki {% endembed %} *** ## To-Do * Use [Discoverable Partitions](https://uapi-group.org/specifications/specs/discoverable_partitions_specification/) to remove the need for UUID. Ensure it is supported for btrfs. * btrfs based swap support might be nice to add just to safeguard against applications that might need it. ## Useful Resources * [Zapping](https://www.rodsbooks.com/gdisk/wipegpt.html) MBR and/or GPT on the disk. *** ## ArchISO Commands {% code overflow="wrap" %} ```bash # check if internet connection is available ping archlinux.org # Wi-Fi iwctl --passphrase station connect # Activate SSH for ArchISO passwd ip add localectl list-keymaps loadkeys ie # 64 for UEFI cat /sys/firmware/efi/fw_platform_size # check if time is right timedatectl # check which drive to use, nvme0nX or sdaX lsblk # gdisk /dev/sda, expert mode to zap it if needed. cfdisk /dev/sda # EFI 1GB, rest linux filesystem # format the partitions mkfs.fat -F 32 /dev/sda1 mkfs.btrfs /dev/sda2 # mount, create subvolumes, unmount mount /dev/sda2 /mnt btrfs subvolume create /mnt/@ btrfs subvolume create /mnt/@home umount -R /mnt # mount the subvolumes and efi mount -o defaults,compress=zstd,subvol=@ /dev/sda2 /mnt mount --mkdir -o defaults,compress=zstd,subvol=@home /dev/sda2 /mnt/home mount --mkdir /dev/sda1 /mnt/efi # check mirrors, set parallel downloads on cat /etc/pacman.d/mirrorlist vim /etc/pacman.conf # pacstrap stuff # install either amd-ucode or intel-ucode pacstrap -K /mnt base base-devel linux linux-firmware bash-completion btrfs-progs timeshift sbctl zram-generator nano neovim networkmanager iwd openssh git wget reflector zsh man-db man-pages texinfo tldr amd-ucode # Add grub and efibootmgr if installing GRUB # generate fstab genfstab -U /mnt >> /mnt/etc/fstab cat /mnt/etc/fstab # CHROOT INTO SYSTEM arch-chroot /mnt ln -sf /usr/share/zoneinfo/Europe/Dublin /etc/localtime hwclock --systohc nvim /etc/locale.gen # uncomment locale locale-gen echo "LANG=en_IE.UTF-8" > /etc/locale.conf echo "KEYMAP=ie" > /etc/vconsole.conf echo "arch" > /etc/hostname # users n stuff passwd useradd -m -G wheel -s /bin/zsh spec passwd spec EDITOR=nvim visudo # uncomment wheel # parallel downloads nvim /etc/pacman.conf # 32 bit support # !!! enable multilib here too !!! pacman -Syy # zsh init su spec # 1 10 21 31e0 0 exit # systemd-boot install ls /sys/firmware/efi/efivars # if files are available, UEFI boot is on # check wiki otherwise bootctl install # Kernel parameters echo "root=UUID=$(blkid -s UUID -o value /dev/sda2) rootflags=subvol=@ rw quiet splash" > /etc/kernel/cmdline # UKI (i couldnt get the normal systemd-boot to work with btrfs lole) # this is better anyway we ball sbctl create-keys sbctl enroll-keys -m # verify won't work within chroot, it is to check which files to sign sbctl verify sbctl sign -s /boot/vmlinuz-linux sbctl sign -s /boot/EFI/BOOT/BOOTX64.EFI sbctl bundle --amducode /boot/amd-ucode.img --save /efi/EFI/Linux/arch-linux.efi sbctl generate-bundles --sign # set iwd as wifi backend for networkmanager nvim /etc/NetworkManager/conf.d/wifi_backend.conf [device] wifi.backend=iwd # install zram nvim /etc/systemd/zram-generator.conf [zram0] zram-size = min(ram / 2, 4096) compression-algorithm = zstd swap-priority = 100 fs-type = swap nvim /etc/sysctl.d/99-vm-zram-parameters.conf vm.swappiness = 180 vm.watermark_boost_factor = 0 vm.watermark_scale_factor = 125 vm.page-cluster = 0 # if zram schtuff was done outside of chroot systemctl daemon-reload systemctl enable /dev/zram0 systemctl start /dev/zram0 systemctl status systemd-zram-setup@zram0.service # systemd stuff systemctl enable NetworkManager.service systemctl enable systemd-timesyncd.service systemctl enable sshd.service # exit chroot exit # or C-d umount -R /mnt reboot ``` {% endcode %} *** ## NVIDIA (Sadge)
