2 2 ## Introduction
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` and `stretch`. Raspberry Pi 3 images are currently generated for 32-bit mode only.
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` and `stretch`. 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 mandetory. 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

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 A comma separated list of additional packages to be installed during bootstrapping.
61 A comma separated list of additional packages to be installed by debootstrap during bootstrapping.

304 328 Remove all doc files (harsh). Configure APT to not include doc files on future `apt-get` package installations.
305 329
306 330 ##### `REDUCE_MAN`=true
307 331 Remove all man pages and info files (harsh). Configure APT to not include man pages on future `apt-get` package installations.
308 332
309 333 ##### `REDUCE_VIM`=false
310 334 Replace `vim-tiny` package by `levee` a tiny vim clone.
311 335
312 336 ##### `REDUCE_BASH`=false
313 337 Remove `bash` package and switch to `dash` shell (experimental).
314 338
315 339 ##### `REDUCE_HWDB`=true
316 340 Remove PCI related hwdb files (experimental).
317 341
318 342 ##### `REDUCE_SSHD`=true
319 343 Replace `openssh-server` with `dropbear`.
320 344

325 349
326 350 #### Encrypted root partition:
327 351 ##### `ENABLE_CRYPTFS`=false
328 352 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.
329 353
330 354 ##### `CRYPTFS_PASSWORD`=""
331 355 Set password of the encrypted root partition. This parameter is mandatory if `ENABLE_CRYPTFS`=true.
332 356
333 357 ##### `CRYPTFS_MAPPING`="secure"
334 358 Set name of dm-crypt managed device-mapper mapping.
335 359
336 360 ##### `CRYPTFS_CIPHER`="aes-xts-plain64:sha512"
337 361 Set cipher specification string. `aes-xts*` ciphers are strongly recommended.
338 362
339 363 ##### `CRYPTFS_XTSKEYSIZE`=512
340 364 Sets key size in bits. The argument has to be a multiple of 8.
341 365
342 366 ---
343 367
344 368 #### Build settings:
345 369 ##### `BASEDIR`=$(pwd)/images/${RELEASE}
346 370 Set a path to a working directory used by the script to generate an image.
347 371
348 ##### `IMAGE_NAME`=${BASEDIR}/${DATE}-rpi${RPI_MODEL}-${RELEASE}
349 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 $IMAGE_NAME-root.img if `ENABLE_SPLITFS`=true.
372 ##### `IMAGE_NAME`=${BASEDIR}/${DATE}-${KERNEL_ARCH}-${KERNEL_BRANCH}-rpi${RPI_MODEL}-${RELEASE}-${RELEASE_ARCH}
373 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.
350 374
351 375 ## Understanding the script
352 376 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:
353 377
354 378 | Script | Description |
355 379 | --- | --- |
356 380 | `10-bootstrap.sh` | Debootstrap basic system |
357 381 | `11-apt.sh` | Setup APT repositories |
358 382 | `12-locale.sh` | Setup Locales and keyboard settings |
359 383 | `13-kernel.sh` | Build and install RPi2/3 Kernel |
360 384 | `14-fstab.sh` | Setup fstab and initramfs |
361 385 | `15-rpi-config.sh` | Setup RPi2/3 config and cmdline |
362 386 | `20-networking.sh` | Setup Networking |
363 387 | `21-firewall.sh` | Setup Firewall |
364 388 | `30-security.sh` | Setup Users and Security settings |
365 389 | `31-logging.sh` | Setup Logging |
366 390 | `32-sshd.sh` | Setup SSH and public keys |
367 391 | `41-uboot.sh` | Build and Setup U-Boot |
368 392 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
369 393 | `50-firstboot.sh` | First boot actions |
370 394 | `99-reduce.sh` | Reduce the disk space usage |
371 395
372 396 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.
373 397
374 398 | Directory | Description |
375 399 | --- | --- |
376 400 | `apt` | APT management configuration files |
377 401 | `boot` | Boot and RPi2/3 configuration files |
378 402 | `dpkg` | Package Manager configuration |
379 403 | `etc` | Configuration files and rc scripts |
380 404 | `firstboot` | Scripts that get executed on first boot |
381 405 | `initramfs` | Initramfs scripts |
382 406 | `iptables` | Firewall configuration files |
383 407 | `locales` | Locales configuration |
384 408 | `modules` | Kernel Modules configuration |
385 409 | `mount` | Fstab configuration |
386 410 | `network` | Networking configuration files |
387 411 | `sysctl.d` | Swapping and Network Hardening configuration |
388 412 | `xorg` | fbturbo Xorg driver configuration |
389 413
390 414 ## Custom packages and scripts
391 415 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`.
392 416
393 417 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
394 418
395 419 ## Logging of the bootstrapping process
396 420 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:
397 421
398 422 ```shell
399 423 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
400 424 ```
401 425
402 426 ## Flashing the image file
403 427 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`.
404 428
405 429 #####Flashing examples:
406 430 ```shell
407 431 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie.img /dev/mmcblk0
408 432 dd bs=4M if=./images/jessie/2017-01-23-rpi3-jessie.img of=/dev/mmcblk0
409 433 ```
410 434 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
411 435 ```shell
412 436 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-frmw.img /dev/mmcblk0
413 437 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-root.img /dev/sdc
414 438 ```
439 ## Weekly image builds
440 The image files are provided by JRWR'S I/O PORT and are built once a Sunday at midnight UTC!
