  • I’m using Arch because you start with nothing and you can make any system you want. I have disk encryption, btrfs as a filesystem, secure boot with my own custom keys, I’m running self-build kernel, I’m using apparmor and I can use any program from AUR, etc. Thats my personality. Things that you can’t see but are important to me.

    On other distros some of these things would be very hard to do. Especially without Arch Wiki.

    I switched from Docker to Podman, because Podman is more secure (if rootless) but it was just hard to autostart containars. You have to start one by one because they don’t have a central service like docker. And watchtower and nextcloud AIO don’t work on Podman. So I switched back to docker.








  • That was really hard to do. I created a note for myself and I will also publish it on my website. You can also decrypt the sd using fido2 hardware key (I have a nitrokey). If you don’t need that just skip steps that are for fido2.

    The note:

    Download the image.

    Format SD card to new DOS table:

    • Boot: 512M 0c W95 FAT32 (LBA)
    • Root: 83 Linux

    As root:

    xz -d 2023-12-11-raspios-bookworm-arm64-lite.img.xz
    losetup -fP 2023-12-11-raspios-bookworm-arm64-lite.img
    dd if=/dev/loop0p1 of=/dev/mmcblk0p1 bs=1M
    cryptsetup luksFormat --type=luks2 --cipher=xchacha20,aes-adiantum-plain64 /dev/mmcblk0p2
    systemd-cryptenroll --fido2-device=auto /dev/mmcblk0p2
    cryptsetup open /dev/mmcblk0p2 root
    dd if=/dev/loop0p2 of=/dev/mapper/root bs=1M
    e2fsck -f /dev/mapper/root
    resize2fs -f /dev/mapper/root
    mount /dev/mapper/root /mnt
    mount /dev/mmcblk0p1 /mnt/boot/firmware
    arch-chroot /mnt
    

    In chroot:

    apt update && apt full-upgrade -y && apt autoremove -y && apt install cryptsetup-initramfs fido2-tools jq debhelper git vim -y
    git clone https://github.com/bertogg/fido2luks && cd fido2luks
    fakeroot debian/rules binary && sudo apt install ../fido2luks*.deb
    cd .. && rm -rf fido2luks*
    

    Edit /etc/crypttab:

    root            /dev/mmcblk0p2          none            luks,keyscript=/lib/fido2luks/keyscript.sh
    

    Edit /etc/fstab:

    /dev/mmcblk0p1    /boot/firmware  vfat    defaults          0       2
    /dev/mapper/root  /               ext4    defaults,noatime  0       1
    

    Change root to /dev/mapper/root and add cryptdevice=/dev/mmcblk0p2:root to /boot/firmware/cmdline.txt.

    PATH="$PATH:/sbin"
    update-initramfs -u
    

    Exit chroot and finish!

    umount -R /mnt
