1 1 # rpi23-gen-image
2 2 ## Introduction
3 3 `rpi23-gen-image.sh` is an advanced Debian Linux bootstrapping shell script for generating Debian OS images for Raspberry Pi 2 (RPi2) and Raspberry Pi 3 (RPi3) computers. The script at this time supports the bootstrapping of the Debian (armhf) releases `jessie`, `stretch` and `buster`. Raspberry Pi 3 images are generated for 32-bit mode only. Raspberry Pi 3 64-bit images can be generated using custom configuration parameters (```templates/rpi3-stretch-arm64-4.11.y```).
4 4
5 5 ## Build dependencies
6 6 The following list of Debian packages must be installed on the build system because they are essentially required for the bootstrapping process. The script will check if all required packages are installed and missing packages will be installed automatically if confirmed by the user.
7 7
8 8 ```debootstrap debian-archive-keyring qemu-user-static binfmt-support dosfstools rsync bmap-tools whois git bc psmisc dbus sudo```
9 9
10 10 It is recommended to configure the `rpi23-gen-image.sh` script to build and install the latest Raspberry Pi Linux kernel. For the RPi3 this is mandatory. Kernel compilation and linking will be performed on the build system using an ARM (armhf) cross-compiler toolchain.
11 11
12 12 The script has been tested using the default `crossbuild-essential-armhf` toolchain meta package on Debian Linux `jessie` and `stretch` build systems. Please check the [Debian CrossToolchains Wiki](https://wiki.debian.org/CrossToolchains) for further information.
13 13
14 14 If a Debian Linux `jessie` build system is used it will be required to add the [Debian Cross-toolchains repository](http://emdebian.org/tools/debian/) first:
15 15
16 16 ```
17 17 echo "deb http://emdebian.org/tools/debian/ jessie main" > /etc/apt/sources.list.d/crosstools.list
18 18 sudo -u nobody wget -O - http://emdebian.org/tools/debian/emdebian-toolchain-archive.key | apt-key add -
19 19 dpkg --add-architecture armhf
20 20 apt-get update
21 21 ```
22 22
23 23 ## Command-line parameters
24 24 The script accepts certain command-line parameters to enable or disable specific OS features, services and configuration settings. These parameters are passed to the `rpi23-gen-image.sh` script via (simple) shell-variables. Unlike environment shell-variables (simple) shell-variables are defined at the beginning of the command-line call of the `rpi23-gen-image.sh` script.
25 25
26 26 ##### Command-line examples:
27 27 ```shell
28 28 ENABLE_UBOOT=true ./rpi23-gen-image.sh
29 29 ENABLE_CONSOLE=false ENABLE_IPV6=false ./rpi23-gen-image.sh

39 39 RPI_MODEL=3 ENABLE_WIRELESS=true ENABLE_MINBASE=true BUILD_KERNEL=true ./rpi23-gen-image.sh
40 40 RELEASE=stretch RPI_MODEL=3 ENABLE_WIRELESS=true ENABLE_MINBASE=true BUILD_KERNEL=true ./rpi23-gen-image.sh
41 41 ```
42 42
43 43 ## Configuration template files
44 44 To avoid long lists of command-line parameters and to help to store the favourite parameter configurations the `rpi23-gen-image.sh` script supports so called configuration template files (`CONFIG_TEMPLATE`=template). These are simple text files located in the `./templates` directory that contain the list of configuration parameters that will be used. New configuration template files can be added to the `./templates` directory.
45 45
46 46 ##### Command-line examples:
47 47 ```shell
48 48 CONFIG_TEMPLATE=rpi3stretch ./rpi23-gen-image.sh
49 49 CONFIG_TEMPLATE=rpi2stretch ./rpi23-gen-image.sh
50 50 ```
51 51
52 52 ## Supported parameters and settings
53 53 #### APT settings:
54 54 ##### `APT_SERVER`="ftp.debian.org"
55 55 Set Debian packages server address. Choose a server from the list of Debian worldwide [mirror sites](https://www.debian.org/mirror/list). Using a nearby server will probably speed-up all required downloads within the bootstrapping process.
56 56
57 57 ##### `APT_PROXY`=""
58 58 Set Proxy server address. Using a local Proxy-Cache like `apt-cacher-ng` will speed-up the bootstrapping process because all required Debian packages will only be downloaded from the Debian mirror site once.
59 59
60 60 ##### `APT_INCLUDES`=""
61 61 A comma separated list of additional packages to be installed by debootstrap during bootstrapping.
62 62
63 63 ##### `APT_INCLUDES_LATE`=""
64 64 A comma separated list of additional packages to be installed by apt after bootstrapping and after APT sources are set up. This is useful for packages with pre-depends, which debootstrap do not handle well.

333 336 The directory (`firmware`) containing a local copy of the firmware from the [RaspberryPi firmware project](https://github.com/raspberrypi/firmware). Default is to download the latest firmware directly from the project.
334 337
335 338 ---
336 339
337 340 #### Reduce disk usage:
338 341 The following list of parameters is ignored if `ENABLE_REDUCE`=false.
339 342
340 343 ##### `REDUCE_APT`=true
341 344 Configure APT to use compressed package repository lists and no package caching files.
342 345
343 346 ##### `REDUCE_DOC`=true
344 347 Remove all doc files (harsh). Configure APT to not include doc files on future `apt-get` package installations.
345 348
346 349 ##### `REDUCE_MAN`=true
347 350 Remove all man pages and info files (harsh). Configure APT to not include man pages on future `apt-get` package installations.
348 351
349 352 ##### `REDUCE_VIM`=false
350 353 Replace `vim-tiny` package by `levee` a tiny vim clone.
351 354
352 355 ##### `REDUCE_BASH`=false
353 356 Remove `bash` package and switch to `dash` shell (experimental).
354 357
355 358 ##### `REDUCE_HWDB`=true
356 359 Remove PCI related hwdb files (experimental).
357 360
358 361 ##### `REDUCE_SSHD`=true
359 362 Replace `openssh-server` with `dropbear`.
360 363
361 364 ##### `REDUCE_LOCALE`=true
362 365 Remove all `locale` translation files.
363 366
364 367 ---
365 368
366 369 #### Encrypted root partition:
367 370 ##### `ENABLE_CRYPTFS`=false
368 371 Enable full system encryption with dm-crypt. Setup a fully LUKS encrypted root partition (aes-xts-plain64:sha512) and generate required initramfs. The /boot directory will not be encrypted. This parameter will be ignored if `BUILD_KERNEL`=false. `ENABLE_CRYPTFS` is experimental. SSH-to-initramfs is currently not supported but will be soon - feel free to help.
369 372
370 373 ##### `CRYPTFS_PASSWORD`=""
371 374 Set password of the encrypted root partition. This parameter is mandatory if `ENABLE_CRYPTFS`=true.
372 375
373 376 ##### `CRYPTFS_MAPPING`="secure"
374 377 Set name of dm-crypt managed device-mapper mapping.
375 378
376 379 ##### `CRYPTFS_CIPHER`="aes-xts-plain64:sha512"
377 380 Set cipher specification string. `aes-xts*` ciphers are strongly recommended.
378 381
379 382 ##### `CRYPTFS_XTSKEYSIZE`=512
380 383 Sets key size in bits. The argument has to be a multiple of 8.
381 384
382 385 ---
383 386
384 387 #### Build settings:
385 388 ##### `BASEDIR`=$(pwd)/images/${RELEASE}
386 389 Set a path to a working directory used by the script to generate an image.
387 390
388 391 ##### `IMAGE_NAME`=${BASEDIR}/${DATE}-${KERNEL_ARCH}-${KERNEL_BRANCH}-rpi${RPI_MODEL}-${RELEASE}-${RELEASE_ARCH}
389 392 Set a filename for the output file(s). Note: the script will create $IMAGE_NAME.img if `ENABLE_SPLITFS`=false or $IMAGE_NAME-frmw.img and $IMAGE_NAME-root.img if `ENABLE_SPLITFS`=true. Note 2: If the KERNEL_BRANCH is not set, the word "CURRENT" is used.
390 393
391 394 ## Understanding the script
392 395 The functions of this script that are required for the different stages of the bootstrapping are split up into single files located inside the `bootstrap.d` directory. During the bootstrapping every script in this directory gets executed in lexicographical order:
393 396
394 397 | Script | Description |
395 398 | --- | --- |
396 399 | `10-bootstrap.sh` | Debootstrap basic system |
397 400 | `11-apt.sh` | Setup APT repositories |
398 401 | `12-locale.sh` | Setup Locales and keyboard settings |
399 402 | `13-kernel.sh` | Build and install RPi2/3 Kernel |
400 403 | `14-fstab.sh` | Setup fstab and initramfs |
401 404 | `15-rpi-config.sh` | Setup RPi2/3 config and cmdline |
402 405 | `20-networking.sh` | Setup Networking |
403 406 | `21-firewall.sh` | Setup Firewall |
404 407 | `30-security.sh` | Setup Users and Security settings |
405 408 | `31-logging.sh` | Setup Logging |
406 409 | `32-sshd.sh` | Setup SSH and public keys |
407 410 | `41-uboot.sh` | Build and Setup U-Boot |
408 411 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
409 412 | `50-firstboot.sh` | First boot actions |
410 413 | `99-reduce.sh` | Reduce the disk space usage |
411 414
412 415 All the required configuration files that will be copied to the generated OS image are located inside the `files` directory. It is not recommended to modify these configuration files manually.
413 416
414 417 | Directory | Description |
415 418 | --- | --- |
416 419 | `apt` | APT management configuration files |
417 420 | `boot` | Boot and RPi2/3 configuration files |
418 421 | `dpkg` | Package Manager configuration |
419 422 | `etc` | Configuration files and rc scripts |
420 423 | `firstboot` | Scripts that get executed on first boot |
421 424 | `initramfs` | Initramfs scripts |
422 425 | `iptables` | Firewall configuration files |
423 426 | `locales` | Locales configuration |
424 427 | `modules` | Kernel Modules configuration |
425 428 | `mount` | Fstab configuration |
426 429 | `network` | Networking configuration files |
427 430 | `sysctl.d` | Swapping and Network Hardening configuration |
428 431 | `xorg` | fbturbo Xorg driver configuration |
429 432
430 433 ## Custom packages and scripts
431 434 Debian custom packages, i.e. those not in the debian repositories, can be installed by placing them in the `packages` directory. They are installed immediately after packages from the repositories are installed. Any dependencies listed in the custom packages will be downloaded automatically from the repositories. Do not list these custom packages in `APT_INCLUDES`.
432 435
433 436 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
434 437
435 438 ## Logging of the bootstrapping process
436 439 All information related to the bootstrapping process and the commands executed by the `rpi23-gen-image.sh` script can easily be saved into a logfile. The common shell command `script` can be used for this purpose:
437 440
438 441 ```shell
439 442 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
440 443 ```
441 444
442 445 ## Flashing the image file
443 446 After the image file was successfully created by the `rpi23-gen-image.sh` script it can be copied to the microSD card that will be used by the RPi2/3 computer. This can be performed by using the tools `bmaptool` or `dd`. Using `bmaptool` will probably speed-up the copy process because `bmaptool` copies more wisely than `dd`.
444 447
445 448 ##### Flashing examples:
446 449 ```shell
447 450 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie.img /dev/mmcblk0
448 451 dd bs=4M if=./images/jessie/2017-01-23-rpi3-jessie.img of=/dev/mmcblk0
449 452 ```
450 453 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
451 454 ```shell
452 455 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-frmw.img /dev/mmcblk0
453 456 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-root.img /dev/sdc
454 457 ```
455 458
456 459 ## QEMU emulation
457 460 Start QEMU full system emulation:
458 461 ```shell
459 462 qemu-system-arm -m 2048M -M vexpress-a15 -cpu cortex-a15 -kernel kernel7.img -no-reboot -dtb vexpress-v2p-ca15_a7.dtb -sd ${IMAGE_NAME}.qcow2 -append "root=/dev/mmcblk0p2 rw rootfstype=ext4 console=tty1"
460 463 ```
461 464
462 465 Start QEMU full system emulation and output to console:
463 466 ```shell
464 467 qemu-system-arm -m 2048M -M vexpress-a15 -cpu cortex-a15 -kernel kernel7.img -no-reboot -dtb vexpress-v2p-ca15_a7.dtb -sd ${IMAGE_NAME}.qcow2 -append "root=/dev/mmcblk0p2 rw rootfstype=ext4 console=ttyAMA0,115200 init=/bin/systemd" -serial stdio
465 468 ```
466 469
467 470 Start QEMU full system emulation with SMP and output to console:
468 471 ```shell
469 472 qemu-system-arm -m 2048M -M vexpress-a15 -cpu cortex-a15 -smp cpus=2,maxcpus=2 -kernel kernel7.img -no-reboot -dtb vexpress-v2p-ca15_a7.dtb -sd ${IMAGE_NAME}.qcow2 -append "root=/dev/mmcblk0p2 rw rootfstype=ext4 console=ttyAMA0,115200 init=/bin/systemd" -serial stdio
470 473 ```
471 474
472 475 Start QEMU full system emulation with cryptfs, initramfs and output to console:
473 476 ```shell
474 477 qemu-system-arm -m 2048M -M vexpress-a15 -cpu cortex-a15 -kernel kernel7.img -no-reboot -dtb vexpress-v2p-ca15_a7.dtb -sd ${IMAGE_NAME}.qcow2 -initrd "initramfs-${KERNEL_VERSION}" -append "root=/dev/mapper/secure cryptdevice=/dev/mmcblk0p2:secure rw rootfstype=ext4 console=ttyAMA0,115200 init=/bin/systemd" -serial stdio
475 478 ```
