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 all Raspberry Pi computers. The script at this time supports the bootstrapping of the Debian (armhf/armel) releases `stretch` and `buster`. Raspberry Pi 0/1/2/3 images are generated for 32-bit mode only. Raspberry Pi 3 supports 64-bit images that 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 Raspberry 3 this is mandatory. Kernel compilation and linking will be performed on the build system using an ARM (armhf/armel) cross-compiler toolchain.
11 11
12 12 The script has been tested using the default `crossbuild-essential-armhf` and `crossbuild-essential-armel` toolchain meta packages 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
22 22 ENABLE_HARDNET=true ENABLE_IPTABLES=true /rpi23-gen-image.sh
23 23 APT_SERVER=ftp.de.debian.org APT_PROXY="http://127.0.0.1:3142/" ./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.
56 56
57 57 ---
58 58
59 59 #### General system settings:
60 60 ##### `SET_ARCH`=32
61 61 Set Architecture to default 32bit. If you want to compile 64-bit (RPI3 or RPI3+) set it to `64`. This option will set every needed cross-compiler or board specific option for a successful build.
62 62
63 63 ##### `RPI_MODEL`=2
64 64 Specify the target Raspberry Pi hardware model. The script at this time supports the following Raspberry Pi models:
65 65 - `0` = Raspberry Pi 0 and Raspberry Pi 0 W
66 66 - `1` = Raspberry Pi 1 model A and B
67 67 - `1P` = Raspberry Pi 1 model B+ and A+
68 68 - `2` = Raspberry Pi 2 model B
69 69 - `3` = Raspberry Pi 3 model B
70 70 - `3P` = Raspberry Pi 3 model B+
71 71
72 72 ##### `RELEASE`="buster"
73 73 Set the desired Debian release name. The script at this time supports the bootstrapping of the Debian releases `stretch` and `buster`.
74 74
75 75 ##### `RELEASE_ARCH`="armhf"
76 76 Set the desired Debian release architecture.
77 77
78 78 ##### `HOSTNAME`="rpi$RPI_MODEL-$RELEASE"
79 79 Set system hostname. It's recommended that the hostname is unique in the corresponding subnet.
80 80
81 81 ##### `PASSWORD`="raspberry"
82 82 Set system `root` password. It's **STRONGLY** recommended that you choose a custom password.
83 83
84 84 ##### `USER_PASSWORD`="raspberry"
85 85 Set password for the created non-root user `USER_NAME`=pi. Ignored if `ENABLE_USER`=false. It's **STRONGLY** recommended that you choose a custom password.
86 86
87 87 ##### `DEFLOCAL`="en_US.UTF-8"
88 88 Set default system locale. This setting can also be changed inside the running OS using the `dpkg-reconfigure locales` command. Please note that on using this parameter the script will automatically install the required packages `locales`, `keyboard-configuration` and `console-setup`.
89 89
90 90 ##### `TIMEZONE`="Europe/Berlin"
91 91 Set default system timezone. All available timezones can be found in the `/usr/share/zoneinfo/` directory. This setting can also be changed inside the running OS using the `dpkg-reconfigure tzdata` command.
92 92
93 93 ##### `EXPANDROOT`=true
94 94 Expand the root partition and filesystem automatically on first boot.
95 95
96 96 ##### `ENABLE_QEMU`=false

149 149
150 150 ---
151 151
152 152 #### Basic system features:
153 153 ##### `ENABLE_CONSOLE`=true
154 154 Enable serial console interface. Recommended if no monitor or keyboard is connected to the RPi2/3. In case of problems fe. if the network (auto) configuration failed - the serial console can be used to access the system. On RPI `0` `3` `3P` the CPU speed is locked at lowest speed.
155 155
156 156 ##### `ENABLE_PRINTK`=false
157 157 Enables printing kernel messages to konsole. printk is `3 4 1 3` as in raspbian.
158 158
159 159 ##### `ENABLE_BLUETOOTH`=false
160 160 Enable onboard Bluetooth interface on the RPi0/3/3P. See: [Configuring the GPIO serial port on Raspbian jessie and stretch](https://spellfoundry.com/2016/05/29/configuring-gpio-serial-port-raspbian-jessie-including-pi-3/).
161 161
162 162 ##### `ENABLE_MINIUART_OVERLAY`=false
163 163 Enable Bluetooth to use this. Adds overlay to swap UART0 with UART1. Enabling (slower) Bluetooth and full speed serial console. - RPI `0` `3` `3P` have a fast `hardware UART0` (ttyAMA0) and a `mini UART1` (ttyS0)! RPI `1` `1P` `2` only have a `hardware UART0`. `UART0` is considered better, because is faster and more stable than `mini UART1`. By default the Bluetooth modem is mapped to the `hardware UART0` and `mini UART` is used for console. The `mini UART` is a problem for the serial console, because its baudrate depends on the CPU frequency, which is changing on runtime. Resulting in a volatile baudrate and thus in an unusable serial console.
164 164
165 165 ##### `ENABLE_TURBO`=false
166 166 Enable Turbo mode. This setting locks cpu at the highest frequency. As setting ENABLE_CONSOLE=true locks RPI to lowest CPU speed, this is can be used additionally to lock cpu hat max speed. Need a good power supply and probably cooling for the Raspberry PI.
167 167
168 168 ##### `ENABLE_I2C`=false
169 169 Enable I2C interface on the RPi 0/1/2/3. Please check the [RPi 0/1/2/3 pinout diagrams](https://elinux.org/RPi_Low-level_peripherals) to connect the right GPIO pins.
170 170
171 171 ##### `ENABLE_SPI`=false
172 172 Enable SPI interface on the RPi 0/1/2/3. Please check the [RPi 0/1/2/3 pinout diagrams](https://elinux.org/RPi_Low-level_peripherals) to connect the right GPIO pins.
173 173
174 174 ##### `ENABLE_IPV6`=true
175 175 Enable IPv6 support. The network interface configuration is managed via systemd-networkd.
176 176
177 177 ##### `ENABLE_SSHD`=true
178 178 Install and enable OpenSSH service. The default configuration of the service doesn't allow `root` to login. Please use the user `pi` instead and `su -` or `sudo` to execute commands as root.
179 179
180 180 ##### `ENABLE_NONFREE`=false
181 181 Allow the installation of non-free Debian packages that do not comply with the DFSG. This is required to install closed-source firmware binary blobs.
182 182
183 183 ##### `ENABLE_WIRELESS`=false
184 184 Download and install the [closed-source firmware binary blob](https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm) that is required to run the internal wireless interface of the Raspberry Pi model `3`. This parameter is ignored if the specified `RPI_MODEL` is not `3`.
185 185
186 186 ##### `ENABLE_RSYSLOG`=true
187 187 If set to false, disable and uninstall rsyslog (so logs will be available only in journal files)
188 188
189 189 ##### `ENABLE_SOUND`=true
190 190 Enable sound hardware and install Advanced Linux Sound Architecture.
191 191
192 192 ##### `ENABLE_HWRANDOM`=true
193 193 Enable Hardware Random Number Generator. Strong random numbers are important for most network-based communications that use encryption. It's recommended to be enabled.
194 194
195 195 ##### `ENABLE_MINGPU`=false
196 196 Minimize the amount of shared memory reserved for the GPU. It doesn't seem to be possible to fully disable the GPU.
197 197
198 198 ##### `ENABLE_DBUS`=true
199 199 Install and enable D-Bus message bus. Please note that systemd should work without D-bus but it's recommended to be enabled.
200 200
201 201 ##### `ENABLE_XORG`=false
202 202 Install Xorg open-source X Window System.
203 203
204 204 ##### `ENABLE_WM`=""
205 205 Install a user-defined window manager for the X Window System. To make sure all X related package dependencies are getting installed `ENABLE_XORG` will automatically get enabled if `ENABLE_WM` is used. The `rpi23-gen-image.sh` script has been tested with the following list of window managers: `blackbox`, `openbox`, `fluxbox`, `jwm`, `dwm`, `xfce4`, `awesome`.
206 206
207 207 ##### `ENABLE_SYSVINIT`=false
208 208 Support for halt,init,poweroff,reboot,runlevel,shutdown,telinit commands

214 Enables [Systemd-swap service](https://github.com/Nefelim4ag/systemd-swap). Usefull if `KERNEL_ZSWAP` is enabled.
215
213 216 ##### `ENABLE_MINBASE`=false
214 217 Use debootstrap script variant `minbase` which only includes essential packages and apt. This will reduce the disk usage by about 65 MB.
215 218
216 219 ##### `ENABLE_REDUCE`=false
217 220 Reduce the disk space usage by deleting packages and files. See `REDUCE_*` parameters for detailed information.

409 435
410 436 ## Understanding the script
411 437 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:
412 438
413 439 | Script | Description |
414 440 | --- | --- |
415 441 | `10-bootstrap.sh` | Debootstrap basic system |
416 442 | `11-apt.sh` | Setup APT repositories |
417 443 | `12-locale.sh` | Setup Locales and keyboard settings |
418 444 | `13-kernel.sh` | Build and install RPi 0/1/2/3 Kernel |
419 445 | `14-fstab.sh` | Setup fstab and initramfs |
420 446 | `15-rpi-config.sh` | Setup RPi 0/1/2/3 config and cmdline |
421 447 | `20-networking.sh` | Setup Networking |
422 448 | `21-firewall.sh` | Setup Firewall |
423 449 | `30-security.sh` | Setup Users and Security settings |
424 450 | `31-logging.sh` | Setup Logging |
425 451 | `32-sshd.sh` | Setup SSH and public keys |
426 452 | `41-uboot.sh` | Build and Setup U-Boot |
427 453 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
428 454 | `43-videocore.sh` | Build and Setup videocore libraries |
429 455 | `50-firstboot.sh` | First boot actions |
430 456 | `99-reduce.sh` | Reduce the disk space usage |
431 457
432 458 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.
433 459
434 460 | Directory | Description |
435 461 | --- | --- |
436 462 | `apt` | APT management configuration files |
437 463 | `boot` | Boot and RPi 0/1/2/3 configuration files |
438 464 | `dpkg` | Package Manager configuration |
439 465 | `etc` | Configuration files and rc scripts |
440 466 | `firstboot` | Scripts that get executed on first boot |
441 467 | `initramfs` | Initramfs scripts |
442 468 | `iptables` | Firewall configuration files |
443 469 | `locales` | Locales configuration |
444 470 | `modules` | Kernel Modules configuration |
445 471 | `mount` | Fstab configuration |
446 472 | `network` | Networking configuration files |
447 473 | `sysctl.d` | Swapping and Network Hardening configuration |
448 474 | `xorg` | fbturbo Xorg driver configuration |
449 475
450 476 ## Custom packages and scripts
451 477 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`.
452 478
453 479 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
454 480
455 481 ## Logging of the bootstrapping process
456 482 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:
457 483
458 484 ```shell
459 485 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
460 486 ```
461 487
462 488 ## Flashing the image file
463 489 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 RPi 0/1/2/3 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`.
464 490
465 491 ##### Flashing examples:
466 492 ```shell
467 493 bmaptool copy ./images/buster/2017-01-23-rpi3-buster.img /dev/mmcblk0
468 494 dd bs=4M if=./images/buster/2017-01-23-rpi3-buster.img of=/dev/mmcblk0
469 495 ```
470 496 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
471 497 ```shell
472 498 bmaptool copy ./images/buster/2017-01-23-rpi3-buster-frmw.img /dev/mmcblk0
473 499 bmaptool copy ./images/buster/2017-01-23-rpi3-buster-root.img /dev/sdc
474 500 ```
475 501
476 502 ## QEMU emulation
477 503 Start QEMU full system emulation:
478 504 ```shell
479 505 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"
480 506 ```
481 507
482 508 Start QEMU full system emulation and output to console:
483 509 ```shell
484 510 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
485 511 ```
486 512
487 513 Start QEMU full system emulation with SMP and output to console:
488 514 ```shell
489 515 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
490 516 ```
491 517
492 518 Start QEMU full system emulation with cryptfs, initramfs and output to console:
493 519 ```shell
494 520 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
