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 `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-arm64-4.14.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 `stretch` build systems. Please check the [Debian CrossToolchains Wiki](https://wiki.debian.org/CrossToolchains) for further information.
13 13
14 14 ## Command-line parameters
15 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.
16 16
17 17 ##### Command-line examples:
18 18 ```shell
19 19 ENABLE_UBOOT=true ./rpi23-gen-image.sh
20 20 ENABLE_CONSOLE=false ENABLE_IPV6=false ./rpi23-gen-image.sh
21 21 ENABLE_WM=xfce4 ENABLE_FBTURBO=true ENABLE_MINBASE=true ./rpi23-gen-image.sh

24 24 ENABLE_MINBASE=true ./rpi23-gen-image.sh
25 25 BUILD_KERNEL=true ENABLE_MINBASE=true ENABLE_IPV6=false ./rpi23-gen-image.sh
26 26 BUILD_KERNEL=true KERNELSRC_DIR=/tmp/linux ./rpi23-gen-image.sh
27 27 ENABLE_MINBASE=true ENABLE_REDUCE=true ENABLE_MINGPU=true BUILD_KERNEL=true ./rpi23-gen-image.sh
28 28 ENABLE_CRYPTFS=true CRYPTFS_PASSWORD=changeme EXPANDROOT=false ENABLE_MINBASE=true ENABLE_REDUCE=true ENABLE_MINGPU=true BUILD_KERNEL=true ./rpi23-gen-image.sh
29 29 RELEASE=stretch BUILD_KERNEL=true ./rpi23-gen-image.sh
30 30 RPI_MODEL=3 ENABLE_WIRELESS=true ENABLE_MINBASE=true BUILD_KERNEL=true ./rpi23-gen-image.sh
31 31 RELEASE=stretch RPI_MODEL=3 ENABLE_WIRELESS=true ENABLE_MINBASE=true BUILD_KERNEL=true ./rpi23-gen-image.sh
32 32 ```
33 33
34 34 ## Configuration template files
35 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.
36 36
37 37 ##### Command-line examples:
38 38 ```shell
39 39 CONFIG_TEMPLATE=rpi3stretch ./rpi23-gen-image.sh
40 40 CONFIG_TEMPLATE=rpi2stretch ./rpi23-gen-image.sh
41 41 ```
42 42
43 43 ## Supported parameters and settings
44 44 #### APT settings:
45 45 ##### `APT_SERVER`="ftp.debian.org"
46 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.
47 47
48 48 ##### `APT_PROXY`=""
49 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.
50 50
51 51 ##### `APT_INCLUDES`=""
52 52 A comma separated list of additional packages to be installed by debootstrap during bootstrapping.
53 53
54 54 ##### `APT_INCLUDES_LATE`=""
55 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.

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