Arch Linux & Crypt Root FS

The Problem

My last install of arch did not include the cryptsetup tool in the initrd.img


  • Kernel Boot Parameters
    • dm-crypt
    • arch linux bbs post
      • linux /vmlinuz26 root=/dev/mapper/your-encrypted-device cryptdevice=/dev/sdaX:your-encrypted-device
    • linuxmint forum
      • cd /dev; MAKEDEV generic (outside of chroot)
      • echo ‘CRYPTOPTS=target=sda5_crypt,source=/dev/sda5’ > /etc/initramfs-tools/conf.d/cryptroot
      • (sda5 is my encrypted volume)
      • cp /usr/share/initramfs-tools/hooks/cryptroot /etc/initramfs-tools/hooks/cryptroot
      • cp /usr/share/initramfs-tools/scripts/local-top/cryptroot /etc/initramfs-tools/scripts/local-top/cryptroot
      • update-grub
      • update-initramfs -u (of course)
  • Backup the Crypt Header

    • SHA-1:


    $ sha1sum -c 2013-02-09-wheezy-raspbian.zip.sha1

    2013-02-09-wheezy-raspbian.zip: OK

  3. unzip
  4. determine SD card device name
    • mine is /dev/mmcblk0p1
  5. dd the image to the SD Card – change mmcblk0p1 !!!

    dd bs=4M if=2013-02-09-wheezy-raspbian.zip.sha1 of=/dev/mmcblk0p1

    • check progress:
      • find pid

        ps aux | grep dd

        • my pid is 4149

          $ kill -USR1 4149

          77+0 records in 77+0 records out 322961408 bytes (323 MB) copied, 45.8116 s, 7.0 MB/s

  6. Optional check what’s written to the SD card by dd-ing back to HD and comparing
  7. sync &
  8. umount SD card and insert in Raspberry Pi
