System Configuration

1. Generate fstab:

   mkdir -p /mnt/etc/
   genfstab -t PARTUUID /mnt | grep -v swap > /mnt/etc/fstab
   sed -i "s|vfat.*rw|vfat rw,x-systemd.idle-timeout=1min,x-systemd.automount,noauto,nofail|" /mnt/etc/fstab
   

2. Install packages:

   pacstrap /mnt base mg mandoc grub efibootmgr mkinitcpio
   
   CompatibleVer=$(pacman -Si zfs-linux \
   | grep 'Depends On' \
   | sed "s|.*linux=||" \
   | awk '{ print $1 }')
   
   pacstrap -U /mnt https://archive.archlinux.org/packages/l/linux/linux-${CompatibleVer}-x86_64.pkg.tar.zst
   
   pacstrap /mnt zfs-linux zfs-utils
   
   pacstrap /mnt linux-firmware intel-ucode amd-ucode
   

3. Configure mkinitcpio:

   mv /mnt/etc/mkinitcpio.conf /mnt/etc/mkinitcpio.conf.original
   tee /mnt/etc/mkinitcpio.conf <<EOF
   HOOKS=(base udev autodetect modconf block keyboard zfs filesystems)
   EOF
   

4. Enable internet time synchronisation:

   hwclock --systohc
   systemctl enable systemd-timesyncd --root=/mnt
   

5. Generate host id:

   zgenhostid -f -o /mnt/etc/hostid
   

6. Add archzfs repo:

   curl -L https://archzfs.com/archzfs.gpg |  pacman-key -a - --gpgdir /mnt/etc/pacman.d/gnupg
   pacman-key --lsign-key --gpgdir /mnt/etc/pacman.d/gnupg $(curl -L https://git.io/JsfVS)
   curl -L https://git.io/Jsfw2 > /mnt/etc/pacman.d/mirrorlist-archzfs
   
   tee -a /mnt/etc/pacman.conf <<- 'EOF'
   
   #[archzfs-testing]
   #Include = /etc/pacman.d/mirrorlist-archzfs
   
   [archzfs]
   Include = /etc/pacman.d/mirrorlist-archzfs
   EOF
   

7. Chroot:

   history -w /mnt/home/sys-install-pre-chroot.txt
   arch-chroot /mnt /usr/bin/env DISK="$DISK" bash
   

8. Generate locales:

   echo "en_US.UTF-8 UTF-8" >> /etc/locale.gen
   locale-gen
   

9. Generate initrd:

   mkinitcpio -P
   

10. Import from by-id:

    echo GRUB_CMDLINE_LINUX=\"zfs_import_dir=/dev/disk/by-id/\" >> /etc/default/grub
    

11. Set locale, keymap, timezone, hostname and root password:

    rm -f /etc/localtime
    systemd-firstboot --prompt --force
