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 `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`=""

320 315 ##### `KERNEL_CCACHE`=false
321 316 Compile the kernel using ccache. This speeds up kernel recompilation by caching previous compilations and detecting when the same compilation is being done again.
322 317
323 318 ##### `KERNEL_REMOVESRC`=true
324 319 Remove all kernel sources from the generated OS image after it was built and installed.
325 320
326 321 ##### `KERNELSRC_DIR`=""
327 322 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.
328 323
329 324 ##### `KERNELSRC_CLEAN`=false
330 325 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.
331 326
332 327 ##### `KERNELSRC_CONFIG`=true
333 328 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.
334 329
335 330 ##### `KERNELSRC_USRCONFIG`=""
336 331 Copy own config file to kernel `.config`. If `KERNEL_MENUCONFIG`=true then running after copy.
337 332
338 333 ##### `KERNELSRC_PREBUILT`=false
339 334 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.
340 335
341 336 ##### `RPI_FIRMWARE_DIR`=""
342 337 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.
343 338
344 339 ---
345 340
346 341 #### Reduce disk usage:
347 342 The following list of parameters is ignored if `ENABLE_REDUCE`=false.
348 343
349 344 ##### `REDUCE_APT`=true
350 345 Configure APT to use compressed package repository lists and no package caching files.
351 346
352 347 ##### `REDUCE_DOC`=true
353 348 Remove all doc files (harsh). Configure APT to not include doc files on future `apt-get` package installations.
354 349
355 350 ##### `REDUCE_MAN`=true
356 351 Remove all man pages and info files (harsh). Configure APT to not include man pages on future `apt-get` package installations.
357 352
358 353 ##### `REDUCE_VIM`=false
359 354 Replace `vim-tiny` package by `levee` a tiny vim clone.
360 355
361 356 ##### `REDUCE_BASH`=false
362 357 Remove `bash` package and switch to `dash` shell (experimental).
363 358
364 359 ##### `REDUCE_HWDB`=true
365 360 Remove PCI related hwdb files (experimental).
366 361
367 362 ##### `REDUCE_SSHD`=true

369 364
370 365 ##### `REDUCE_LOCALE`=true
371 366 Remove all `locale` translation files.
372 367
373 368 ---
374 369
375 370 #### Encrypted root partition:
376 371 ##### `ENABLE_CRYPTFS`=false
377 372 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.
378 373
379 374 ##### `CRYPTFS_PASSWORD`=""
380 375 Set password of the encrypted root partition. This parameter is mandatory if `ENABLE_CRYPTFS`=true.
381 376
382 377 ##### `CRYPTFS_MAPPING`="secure"
383 378 Set name of dm-crypt managed device-mapper mapping.
384 379
385 380 ##### `CRYPTFS_CIPHER`="aes-xts-plain64:sha512"
386 381 Set cipher specification string. `aes-xts*` ciphers are strongly recommended.
387 382
388 383 ##### `CRYPTFS_XTSKEYSIZE`=512
389 384 Sets key size in bits. The argument has to be a multiple of 8.
390 385

395 390 Set a path to a working directory used by the script to generate an image.
396 391
397 392 ##### `IMAGE_NAME`=${BASEDIR}/${DATE}-${KERNEL_ARCH}-${KERNEL_BRANCH}-rpi${RPI_MODEL}-${RELEASE}-${RELEASE_ARCH}
398 393 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.
399 394
400 395 ## Understanding the script
401 396 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:
402 397
403 398 | Script | Description |
404 399 | --- | --- |
405 400 | `10-bootstrap.sh` | Debootstrap basic system |
406 401 | `11-apt.sh` | Setup APT repositories |
407 402 | `12-locale.sh` | Setup Locales and keyboard settings |
408 403 | `13-kernel.sh` | Build and install RPi2/3 Kernel |
409 404 | `14-fstab.sh` | Setup fstab and initramfs |
410 405 | `15-rpi-config.sh` | Setup RPi2/3 config and cmdline |
411 406 | `20-networking.sh` | Setup Networking |
412 407 | `21-firewall.sh` | Setup Firewall |
413 408 | `30-security.sh` | Setup Users and Security settings |
414 409 | `31-logging.sh` | Setup Logging |
415 410 | `32-sshd.sh` | Setup SSH and public keys |
416 411 | `41-uboot.sh` | Build and Setup U-Boot |
417 412 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
418 413 | `50-firstboot.sh` | First boot actions |
419 414 | `99-reduce.sh` | Reduce the disk space usage |
420 415
421 416 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.
422 417
423 418 | Directory | Description |
424 419 | --- | --- |
425 420 | `apt` | APT management configuration files |
426 421 | `boot` | Boot and RPi2/3 configuration files |
427 422 | `dpkg` | Package Manager configuration |
428 423 | `etc` | Configuration files and rc scripts |
429 424 | `firstboot` | Scripts that get executed on first boot |
430 425 | `initramfs` | Initramfs scripts |
431 426 | `iptables` | Firewall configuration files |
432 427 | `locales` | Locales configuration |
433 428 | `modules` | Kernel Modules configuration |
434 429 | `mount` | Fstab configuration |
435 430 | `network` | Networking configuration files |
436 431 | `sysctl.d` | Swapping and Network Hardening configuration |
437 432 | `xorg` | fbturbo Xorg driver configuration |
438 433
439 434 ## Custom packages and scripts
440 435 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`.
441 436
442 437 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
443 438
444 439 ## Logging of the bootstrapping process
445 440 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:
446 441
447 442 ```shell
448 443 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
449 444 ```
450 445
451 446 ## Flashing the image file
452 447 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`.
453 448
454 449 ##### Flashing examples:
455 450 ```shell
456 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie.img /dev/mmcblk0
457 dd bs=4M if=./images/jessie/2017-01-23-rpi3-jessie.img of=/dev/mmcblk0
451 bmaptool copy ./images/buster/2017-01-23-rpi3-buster.img /dev/mmcblk0
452 dd bs=4M if=./images/buster/2017-01-23-rpi3-buster.img of=/dev/mmcblk0
458 453 ```
459 454 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
460 455 ```shell
461 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-frmw.img /dev/mmcblk0
462 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-root.img /dev/sdc
456 bmaptool copy ./images/buster/2017-01-23-rpi3-buster-frmw.img /dev/mmcblk0
457 bmaptool copy ./images/buster/2017-01-23-rpi3-buster-root.img /dev/sdc
463 458 ```
464 459
465 460 ## QEMU emulation
466 461 Start QEMU full system emulation:
467 462 ```shell
468 463 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"
469 464 ```
470 465
471 466 Start QEMU full system emulation and output to console:
472 467 ```shell
473 468 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
474 469 ```
475 470
476 471 Start QEMU full system emulation with SMP and output to console:
477 472 ```shell
478 473 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
479 474 ```
480 475
481 476 Start QEMU full system emulation with cryptfs, initramfs and output to console:
482 477 ```shell
483 478 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
484 479 ```
