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
30 30 ENABLE_WM=xfce4 ENABLE_FBTURBO=true ENABLE_MINBASE=true ./rpi23-gen-image.sh

33 33 ENABLE_MINBASE=true ./rpi23-gen-image.sh
34 34 BUILD_KERNEL=true ENABLE_MINBASE=true ENABLE_IPV6=false ./rpi23-gen-image.sh
35 35 BUILD_KERNEL=true KERNELSRC_DIR=/tmp/linux ./rpi23-gen-image.sh
36 36 ENABLE_MINBASE=true ENABLE_REDUCE=true ENABLE_MINGPU=true BUILD_KERNEL=true ./rpi23-gen-image.sh
37 37 ENABLE_CRYPTFS=true CRYPTFS_PASSWORD=changeme EXPANDROOT=false ENABLE_MINBASE=true ENABLE_REDUCE=true ENABLE_MINGPU=true BUILD_KERNEL=true ./rpi23-gen-image.sh
38 38 RELEASE=stretch BUILD_KERNEL=true ./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.

327 327 Copy own config file to kernel `.config`. If `KERNEL_MENUCONFIG`=true then running after copy.
328 328
329 329 ##### `KERNELSRC_PREBUILT`=false
330 330 With this parameter set to true the script expects the existing kernel sources directory to be already successfully cross-compiled. The parameters `KERNELSRC_CLEAN`, `KERNELSRC_CONFIG`, `KERNELSRC_USRCONFIG` and `KERNEL_MENUCONFIG` are ignored and no kernel compilation tasks are performed.
331 331
332 332 ##### `RPI_FIRMWARE_DIR`=""
333 333 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.
334 334
335 335 ---
336 336
337 337 #### Reduce disk usage:
338 338 The following list of parameters is ignored if `ENABLE_REDUCE`=false.
339 339
340 340 ##### `REDUCE_APT`=true
341 341 Configure APT to use compressed package repository lists and no package caching files.
342 342
343 343 ##### `REDUCE_DOC`=true
344 344 Remove all doc files (harsh). Configure APT to not include doc files on future `apt-get` package installations.
345 345
346 346 ##### `REDUCE_MAN`=true
347 347 Remove all man pages and info files (harsh). Configure APT to not include man pages on future `apt-get` package installations.
348 348
349 349 ##### `REDUCE_VIM`=false
350 350 Replace `vim-tiny` package by `levee` a tiny vim clone.
351 351
352 352 ##### `REDUCE_BASH`=false
353 353 Remove `bash` package and switch to `dash` shell (experimental).
354 354
355 355 ##### `REDUCE_HWDB`=true
356 356 Remove PCI related hwdb files (experimental).
357 357
358 358 ##### `REDUCE_SSHD`=true
359 359 Replace `openssh-server` with `dropbear`.
360 360
361 361 ##### `REDUCE_LOCALE`=true
362 362 Remove all `locale` translation files.
363 363
364 364 ---
365 365
366 366 #### Encrypted root partition:
367 367 ##### `ENABLE_CRYPTFS`=false
368 368 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.
369 369
370 370 ##### `CRYPTFS_PASSWORD`=""
371 371 Set password of the encrypted root partition. This parameter is mandatory if `ENABLE_CRYPTFS`=true.
372 372
373 373 ##### `CRYPTFS_MAPPING`="secure"
374 374 Set name of dm-crypt managed device-mapper mapping.
375 375
376 376 ##### `CRYPTFS_CIPHER`="aes-xts-plain64:sha512"
377 377 Set cipher specification string. `aes-xts*` ciphers are strongly recommended.
378 378
379 379 ##### `CRYPTFS_XTSKEYSIZE`=512
380 380 Sets key size in bits. The argument has to be a multiple of 8.
381 381
382 382 ---
383 383
384 384 #### Build settings:
385 385 ##### `BASEDIR`=$(pwd)/images/${RELEASE}
386 386 Set a path to a working directory used by the script to generate an image.
387 387
388 388 ##### `IMAGE_NAME`=${BASEDIR}/${DATE}-${KERNEL_ARCH}-${KERNEL_BRANCH}-rpi${RPI_MODEL}-${RELEASE}-${RELEASE_ARCH}
389 389 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.

391 391 ## Understanding the script
392 392 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:
393 393
394 394 | Script | Description |
395 395 | --- | --- |
396 396 | `10-bootstrap.sh` | Debootstrap basic system |
397 397 | `11-apt.sh` | Setup APT repositories |
398 398 | `12-locale.sh` | Setup Locales and keyboard settings |
399 399 | `13-kernel.sh` | Build and install RPi2/3 Kernel |
400 400 | `14-fstab.sh` | Setup fstab and initramfs |
401 401 | `15-rpi-config.sh` | Setup RPi2/3 config and cmdline |
402 402 | `20-networking.sh` | Setup Networking |
403 403 | `21-firewall.sh` | Setup Firewall |
404 404 | `30-security.sh` | Setup Users and Security settings |
405 405 | `31-logging.sh` | Setup Logging |
406 406 | `32-sshd.sh` | Setup SSH and public keys |
407 407 | `41-uboot.sh` | Build and Setup U-Boot |
408 408 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
409 409 | `50-firstboot.sh` | First boot actions |
410 410 | `99-reduce.sh` | Reduce the disk space usage |
411 411
412 412 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.
413 413
414 414 | Directory | Description |
415 415 | --- | --- |
416 416 | `apt` | APT management configuration files |
417 417 | `boot` | Boot and RPi2/3 configuration files |
418 418 | `dpkg` | Package Manager configuration |
419 419 | `etc` | Configuration files and rc scripts |
420 420 | `firstboot` | Scripts that get executed on first boot |
421 421 | `initramfs` | Initramfs scripts |
422 422 | `iptables` | Firewall configuration files |
423 423 | `locales` | Locales configuration |
424 424 | `modules` | Kernel Modules configuration |
425 425 | `mount` | Fstab configuration |
426 426 | `network` | Networking configuration files |
427 427 | `sysctl.d` | Swapping and Network Hardening configuration |
428 428 | `xorg` | fbturbo Xorg driver configuration |
429 429
430 430 ## Custom packages and scripts
431 431 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`.
432 432
433 433 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
434 434
435 435 ## Logging of the bootstrapping process
436 436 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:
437 437
438 438 ```shell
439 439 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
440 440 ```
441 441
442 442 ## Flashing the image file
443 443 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`.
444 444
445 445 ##### Flashing examples:
446 446 ```shell
447 447 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie.img /dev/mmcblk0
448 448 dd bs=4M if=./images/jessie/2017-01-23-rpi3-jessie.img of=/dev/mmcblk0
449 449 ```
450 450 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
451 451 ```shell
452 452 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-frmw.img /dev/mmcblk0
453 453 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-root.img /dev/sdc
454 454 ```
455 455
456 456 ## QEMU emulation
457 457 Start QEMU full system emulation:
458 458 ```shell
459 459 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"
460 460 ```
461 461
462 462 Start QEMU full system emulation and output to console:
463 463 ```shell
464 464 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
465 465 ```
466 466
467 Start QEMU full system emulation with cryptfs, initramfs and output to console. (NOT WORKING yey!) :
467 Start QEMU full system emulation with cryptfs, initramfs and output to console:
468 468 ```shell
