1 ## Templates used at IFÉ ENS de Lyon for "Tremplin des sciences" project
2
3 These templates have been used to create Raspberry Pi images for the
4 project "Climate and meteorolgy springboard for teaching sciences".
5 These images are tuned andused as explained in the
6 [blog](http://blog.climatetmeteo.fr/GerardVidal/) (mostly in french
7 but under translation).
8
9 The aim is to share with teachers a Raspberry Pi3 binary image providing software resources to use commercial weatherstations or DIY weathersystems made with various sensors. The following images have been built :
10
11 * raspife2-stretch Debian stretch image for raspi 2
12 * raspife3-jessie Debian jessie image for raspi 3
13 * raspife3-stretch Debian stretch image for raspi 3
14 * raspife3W-stretch Debian stretch image for raspi 3 with single IPAddress and weewx service
15 * raspife3-buster Debian buster image for raspi 3
16
17 In these images language ichoosen is french and can easily be changed.
18 Pathes and other variables are the ones that have been used during
19 execution and personnal data are replaced by "*******", change the
20 values according to your needs.

1 1 # rpi23-gen-image
2 2 ## Introduction
3 3
4 4 `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```).
5 5
6
6 7 ## Build dependencies
7 8 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.
8 9
9 10 ```debootstrap debian-archive-keyring qemu-user-static binfmt-support dosfstools rsync bmap-tools whois git bc psmisc dbus sudo```
10 11
11 12 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.
12 13
13 14 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.
14 15
15 16 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:
16 17
17 18 ```
18 19 echo "deb http://emdebian.org/tools/debian/ jessie main" > /etc/apt/sources.list.d/crosstools.list
19 20 sudo -u nobody wget -O - http://emdebian.org/tools/debian/emdebian-toolchain-archive.key | apt-key add -
20 21 dpkg --add-architecture armhf
21 22 apt-get update
22 23 ```
23 24
24 25 ## Command-line parameters
25 26 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.
26 27
27 28 ##### Command-line examples:
28 29 ```shell
29 30 ENABLE_UBOOT=true ./rpi23-gen-image.sh
30 31 ENABLE_CONSOLE=false ENABLE_IPV6=false ./rpi23-gen-image.sh
31 32 ENABLE_WM=xfce4 ENABLE_FBTURBO=true ENABLE_MINBASE=true ./rpi23-gen-image.sh

41 42 RELEASE=stretch RPI_MODEL=3 ENABLE_WIRELESS=true ENABLE_MINBASE=true BUILD_KERNEL=true ./rpi23-gen-image.sh
42 43 ```
43 44
44 45 ## Configuration template files
45 46 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.
46 47
47 48 ##### Command-line examples:
48 49 ```shell
49 50 CONFIG_TEMPLATE=rpi3stretch ./rpi23-gen-image.sh
50 51 CONFIG_TEMPLATE=rpi2stretch ./rpi23-gen-image.sh

361 362 ##### `CRYPTFS_CIPHER`="aes-xts-plain64:sha512"
362 363 Set cipher specification string. `aes-xts*` ciphers are strongly recommended.
363 364
364 365 ##### `CRYPTFS_XTSKEYSIZE`=512
365 366 Sets key size in bits. The argument has to be a multiple of 8.
366 367
367 368 ---
368 369
369 370 #### Build settings:
370 371 ##### `BASEDIR`=$(pwd)/images/${RELEASE}
371 372 Set a path to a working directory used by the script to generate an image.
372 373
373 374 ##### `IMAGE_NAME`=${BASEDIR}/${DATE}-${KERNEL_ARCH}-${KERNEL_BRANCH}-rpi${RPI_MODEL}-${RELEASE}-${RELEASE_ARCH}
374 375 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.
375 376
376 377 ## Understanding the script
377 378 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:
378 379
379 380 | Script | Description |
380 381 | --- | --- |
381 382 | `10-bootstrap.sh` | Debootstrap basic system |
382 383 | `11-apt.sh` | Setup APT repositories |
383 384 | `12-locale.sh` | Setup Locales and keyboard settings |
384 385 | `13-kernel.sh` | Build and install RPi2/3 Kernel |
385 386 | `14-fstab.sh` | Setup fstab and initramfs |
386 387 | `15-rpi-config.sh` | Setup RPi2/3 config and cmdline |
387 388 | `20-networking.sh` | Setup Networking |
388 389 | `21-firewall.sh` | Setup Firewall |
389 390 | `30-security.sh` | Setup Users and Security settings |
390 391 | `31-logging.sh` | Setup Logging |
391 392 | `32-sshd.sh` | Setup SSH and public keys |
392 393 | `41-uboot.sh` | Build and Setup U-Boot |
393 394 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
394 395 | `50-firstboot.sh` | First boot actions |
395 396 | `99-reduce.sh` | Reduce the disk space usage |
396 397
397 398 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.
398 399
399 400 | Directory | Description |
400 401 | --- | --- |
401 402 | `apt` | APT management configuration files |
402 403 | `boot` | Boot and RPi2/3 configuration files |
403 404 | `dpkg` | Package Manager configuration |
404 405 | `etc` | Configuration files and rc scripts |
405 406 | `firstboot` | Scripts that get executed on first boot |
406 407 | `initramfs` | Initramfs scripts |
407 408 | `iptables` | Firewall configuration files |
408 409 | `locales` | Locales configuration |
409 410 | `modules` | Kernel Modules configuration |
410 411 | `mount` | Fstab configuration |
411 412 | `network` | Networking configuration files |
412 413 | `sysctl.d` | Swapping and Network Hardening configuration |
413 414 | `xorg` | fbturbo Xorg driver configuration |
414 415
415 416 ## Custom packages and scripts
416 417 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`.
417 418
418 419 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
419 420
420 421 ## Logging of the bootstrapping process
421 422 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:
422 423
423 424 ```shell
424 425 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
425 426 ```
426 427
427 428 ## Flashing the image file
428 429 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`.
429 430
430 431 ##### Flashing examples:
431 432 ```shell
432 433 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie.img /dev/mmcblk0
433 434 dd bs=4M if=./images/jessie/2017-01-23-rpi3-jessie.img of=/dev/mmcblk0
434 435 ```
435 436 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
436 437 ```shell
437 438 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-frmw.img /dev/mmcblk0
438 439 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-root.img /dev/sdc
439 440 ```
440 441 ## Weekly image builds
