1 1 # rpi23-gen-image
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`, `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 ## 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 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
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
16 ```
17 echo "deb http://emdebian.org/tools/debian/ jessie main" > /etc/apt/sources.list.d/crosstools.list
18 sudo -u nobody wget -O - http://emdebian.org/tools/debian/emdebian-toolchain-archive.key | apt-key add -
19 dpkg --add-architecture armhf
20 apt-get update
21 ```
12 The script has been tested using the default `crossbuild-essential-armhf` toolchain meta package on Debian Linux and `stretch` build systems. Please check the [Debian CrossToolchains Wiki](https://wiki.debian.org/CrossToolchains) for further information.
22 13
23 14 ## Command-line parameters
24 15 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 16
26 17 ##### Command-line examples:
27 18 ```shell
28 19 ENABLE_UBOOT=true ./rpi23-gen-image.sh

41 32 ```
42 33
43 34 ## Configuration template files
44 35 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 36
46 37 ##### Command-line examples:
47 38 ```shell
48 39 CONFIG_TEMPLATE=rpi3stretch ./rpi23-gen-image.sh
49 40 CONFIG_TEMPLATE=rpi2stretch ./rpi23-gen-image.sh
50 41 ```
51 42
52 43 ## Supported parameters and settings
53 44 #### APT settings:
54 45 ##### `APT_SERVER`="ftp.debian.org"
55 46 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 47
57 48 ##### `APT_PROXY`=""
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.
49 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. If `apt-cacher-ng` is running on default `http://127.0.0.1:3142` it is autodetected and you don't need to set this.
59 50
60 51 ##### `APT_INCLUDES`=""
61 52 A comma separated list of additional packages to be installed by debootstrap during bootstrapping.
62 53
63 54 ##### `APT_INCLUDES_LATE`=""
64 55 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.

327 318 Path to a directory (`linux`) of [RaspberryPi Linux kernel sources](https://github.com/raspberrypi/linux) that will be copied, configured, build and installed inside the chroot.
328 319
329 320 ##### `KERNELSRC_CLEAN`=false
330 321 Clean the existing kernel sources directory `KERNELSRC_DIR` (using `make mrproper`) after it was copied to the chroot and before the compilation of the kernel has started. This parameter will be ignored if no `KERNELSRC_DIR` was specified or if `KERNELSRC_PREBUILT`=true.
331 322
332 323 ##### `KERNELSRC_CONFIG`=true
333 324 Run `make bcm2709_defconfig` (and optional `make menuconfig`) to configure the kernel sources before building. This parameter is automatically set to `true` if no existing kernel sources directory was specified using `KERNELSRC_DIR`. This parameter is ignored if `KERNELSRC_PREBUILT`=true.
334 325
335 326 ##### `KERNELSRC_USRCONFIG`=""
336 327 Copy own config file to kernel `.config`. If `KERNEL_MENUCONFIG`=true then running after copy.
337 328
338 329 ##### `KERNELSRC_PREBUILT`=false
339 330 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.
340 331
341 332 ##### `RPI_FIRMWARE_DIR`=""
342 333 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.
343 334
344 335 ---
345 336
346 337 #### Reduce disk usage:
347 338 The following list of parameters is ignored if `ENABLE_REDUCE`=false.
348 339
349 340 ##### `REDUCE_APT`=true
350 341 Configure APT to use compressed package repository lists and no package caching files.
351 342
352 343 ##### `REDUCE_DOC`=true
353 344 Remove all doc files (harsh). Configure APT to not include doc files on future `apt-get` package installations.
354 345
355 346 ##### `REDUCE_MAN`=true
356 347 Remove all man pages and info files (harsh). Configure APT to not include man pages on future `apt-get` package installations.
357 348
358 349 ##### `REDUCE_VIM`=false
359 350 Replace `vim-tiny` package by `levee` a tiny vim clone.
360 351
361 352 ##### `REDUCE_BASH`=false
362 353 Remove `bash` package and switch to `dash` shell (experimental).
363 354
364 355 ##### `REDUCE_HWDB`=true
365 356 Remove PCI related hwdb files (experimental).
366 357
367 358 ##### `REDUCE_SSHD`=true
368 359 Replace `openssh-server` with `dropbear`.
369 360
370 361 ##### `REDUCE_LOCALE`=true
371 362 Remove all `locale` translation files.
372 363
373 364 ---
374 365
375 366 #### Encrypted root partition:
376 367 ##### `ENABLE_CRYPTFS`=false
377 368 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.
378 369
379 370 ##### `CRYPTFS_PASSWORD`=""
380 371 Set password of the encrypted root partition. This parameter is mandatory if `ENABLE_CRYPTFS`=true.
381 372
382 373 ##### `CRYPTFS_MAPPING`="secure"
383 374 Set name of dm-crypt managed device-mapper mapping.
384 375
385 376 ##### `CRYPTFS_CIPHER`="aes-xts-plain64:sha512"
386 377 Set cipher specification string. `aes-xts*` ciphers are strongly recommended.
387 378
388 379 ##### `CRYPTFS_XTSKEYSIZE`=512
389 380 Sets key size in bits. The argument has to be a multiple of 8.
390 381
391 382 ---
392 383
393 384 #### Build settings:
394 385 ##### `BASEDIR`=$(pwd)/images/${RELEASE}
395 386 Set a path to a working directory used by the script to generate an image.
396 387
397 388 ##### `IMAGE_NAME`=${BASEDIR}/${DATE}-${KERNEL_ARCH}-${KERNEL_BRANCH}-rpi${RPI_MODEL}-${RELEASE}-${RELEASE_ARCH}
398 389 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.
399 390
400 391 ## Understanding the script
401 392 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:
402 393
403 394 | Script | Description |
404 395 | --- | --- |
405 396 | `10-bootstrap.sh` | Debootstrap basic system |
406 397 | `11-apt.sh` | Setup APT repositories |
407 398 | `12-locale.sh` | Setup Locales and keyboard settings |
408 399 | `13-kernel.sh` | Build and install RPi2/3 Kernel |
409 400 | `14-fstab.sh` | Setup fstab and initramfs |
410 401 | `15-rpi-config.sh` | Setup RPi2/3 config and cmdline |
411 402 | `20-networking.sh` | Setup Networking |
412 403 | `21-firewall.sh` | Setup Firewall |
413 404 | `30-security.sh` | Setup Users and Security settings |
414 405 | `31-logging.sh` | Setup Logging |
415 406 | `32-sshd.sh` | Setup SSH and public keys |
416 407 | `41-uboot.sh` | Build and Setup U-Boot |
417 408 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
418 409 | `50-firstboot.sh` | First boot actions |
419 410 | `99-reduce.sh` | Reduce the disk space usage |
420 411
421 412 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.
422 413
423 414 | Directory | Description |
424 415 | --- | --- |
425 416 | `apt` | APT management configuration files |
426 417 | `boot` | Boot and RPi2/3 configuration files |
427 418 | `dpkg` | Package Manager configuration |
428 419 | `etc` | Configuration files and rc scripts |
429 420 | `firstboot` | Scripts that get executed on first boot |
430 421 | `initramfs` | Initramfs scripts |
431 422 | `iptables` | Firewall configuration files |
432 423 | `locales` | Locales configuration |
433 424 | `modules` | Kernel Modules configuration |
434 425 | `mount` | Fstab configuration |
435 426 | `network` | Networking configuration files |
436 427 | `sysctl.d` | Swapping and Network Hardening configuration |
437 428 | `xorg` | fbturbo Xorg driver configuration |
438 429
439 430 ## Custom packages and scripts
440 431 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`.
441 432
442 433 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
443 434
444 435 ## Logging of the bootstrapping process
445 436 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:
446 437
447 438 ```shell
448 439 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
449 440 ```
450 441
451 442 ## Flashing the image file
452 443 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`.
453 444
454 445 ##### Flashing examples:
455 446 ```shell
456 447 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie.img /dev/mmcblk0
457 448 dd bs=4M if=./images/jessie/2017-01-23-rpi3-jessie.img of=/dev/mmcblk0
458 449 ```
459 450 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
460 451 ```shell
461 452 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-frmw.img /dev/mmcblk0
462 453 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-root.img /dev/sdc
463 454 ```
464 455
465 456 ## QEMU emulation
466 457 Start QEMU full system emulation:
467 458 ```shell
468 459 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"
469 460 ```
470 461
471 462 Start QEMU full system emulation and output to console:
472 463 ```shell
473 464 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
474 465 ```
475 466
476 467 Start QEMU full system emulation with SMP and output to console:
477 468 ```shell
478 469 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
479 470 ```
480 471
481 472 Start QEMU full system emulation with cryptfs, initramfs and output to console:
482 473 ```shell
483 474 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
484 475 ```
