Raspberry Pi 4BにArch Linux (64it)をインストールしてみました。

https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-4

環境

• Raspberry Pi 4B
• 32GB SDカード
  • Arch Linux

構築

作業PC

1. gpartedでSDカードのパーティションを削除しておく

2. rootで作業する

   su

3. Start fdisk to partition the SD card:

   fdisk /dev/sdX

   私の環境では/dev/sdaでした

4. At the fdisk prompt, delete old partitions and create a new one:

   入力	内容
   o	This will clear out any partitions on the drive
   p	list partitions. There should be no partitions left
   n p 1 ENTER +400M	the first partition on the drive
   t c	set the first partition to type W95 FAT32 (LBA).
   n p 2 ENTER ENTER	the second partition on the drive
   w	Write the partition table and exit

5. Create and mount the FAT filesystem:

   mkfs.vfat /dev/sdX1
   mkdir boot
   mount /dev/sdX1 boot

6. Create and mount the ext4 filesystem:

   mkfs.ext4 /dev/sdX2
   mkdir root
   mount /dev/sdX2 root

7. Download and extract the root filesystem (as root, not via sudo):

   wget http://os.archlinuxarm.org/os/ArchLinuxARM-rpi-aarch64-latest.tar.gz
   bsdtar -xpf ArchLinuxARM-rpi-aarch64-latest.tar.gz -C root
   sync

8. Move boot files to the first partition:

   mv root/boot/* boot

9. Edit fstab

   root/etc/fstab

   # Static information about the filesystems.
   # See fstab(5) for details.
   
   # <file system> <dir> <type> <options> <dump> <pass>
   #/dev/mmcblk0p1  /boot   vfat    defaults        0       0
   /dev/mmcblk1p1  /boot   vfat    defaults        0       0
   /dev/mmcblk1p2  /       ext4    defaults        0       0

10. Unmount the two partitions:

    umount boot root

Raspberry Pi (1)

11. Insert the SD card into the Raspberry Pi, connect ethernet, and apply 5V power.
12. Use the serial console or SSH to the IP address given to the board by your router.

• Login as the default user alarm with the password alarm.
• The default root password is root.

13. rootで作業する

    su

14. Initialize the pacman keyring and populate the Arch Linux ARM package signing keys:

    pacman-key --init
    pacman-key --populate archlinuxarm

15. ミラーの設定

    /etc/pacman.d/mirrorlist

    ### Japan
    ## Tokyo
    # Server = http://jp.mirror.archlinuxarm.org/$arch/$repo
    Server = http://jp.mirror.archlinuxarm.org/$arch/$repo

16. パッケージの更新

    pacman -Syu

17. base-develのインストール

    pacman -S base-devel
    reboot

Raspberry Pi (2)

17. gnomeのインストール

    pacman -S gnome

18. GDMのインストールと有効化

    pacman -S gdm
    systemctl enable gdm

19. タイムゾーンの設定

    curl https://ipapi.co/timezone
    timedatectl set-timezone "Asia/Tokyo"

20. ロケールの設定

    locale-gen
    localectl set-locale LANG="en_US.UTF-8"

21. 再起動

    reboot
