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 releases `jessie` and `stretch`. Raspberry Pi 3 images are currently generated for 32-bit mode only.
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```
9 9
10 10 ## Command-line parameters
11 11 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.
12 12
13 13 #####Command-line examples:
14 14 ```shell
15 15 ENABLE_UBOOT=true ./rpi23-gen-image.sh
16 16 ENABLE_CONSOLE=false ENABLE_IPV6=false ./rpi23-gen-image.sh
17 17 ENABLE_WM=xfce4 ENABLE_FBTURBO=true ENABLE_MINBASE=true ./rpi23-gen-image.sh

30 30 #### APT settings:
31 31 ##### `APT_SERVER`="ftp.debian.org"
32 32 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.
33 33
34 34 ##### `APT_PROXY`=""
35 35 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.
36 36
37 37 ##### `APT_INCLUDES`=""
38 38 A comma separated list of additional packages to be installed during bootstrapping.
39 39
40 40 #### General system settings:
41 41 ##### `RPI_MODEL`=2
42 42 Specifiy the target Raspberry Pi hardware model. The script at this time supports the Raspberry Pi models `2` and `3`. `BUILD_KERNEL`=true will automatically be set if the Raspberry Pi model `3` is used.
43 43
44 44 ##### `RELEASE`="jessie"
45 45 Set the desired Debian release name. The script at this time supports the bootstrapping of the Debian releases "jessie" and "stretch". `BUILD_KERNEL`=true will automatically be set if the Debian release `stretch` is used.
46 46
47 47 ##### `HOSTNAME`="rpi$RPI_MODEL-$RELEASE"
48 48 Set system host name. It's recommended that the host name is unique in the corresponding subnet.
49 49
50 50 ##### `PASSWORD`="raspberry"
51 51 Set system `root` password. The same password is used for the created user `pi`. It's **STRONGLY** recommended that you choose a custom password.
52 52
53 53 ##### `DEFLOCAL`="en_US.UTF-8"
54 54 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`.
55 55
56 56 ##### `TIMEZONE`="Europe/Berlin"
57 57 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.

76 76
77 77 #### Networking settings (DHCP):
78 78 This parameter is used to set up networking auto configuration in `/etc/systemd/network/eth.network`. The default location of network configuration files in the Debian `stretch` release was changed to `/lib/systemd/network`.`
79 79
80 80 #####`ENABLE_DHCP`=true
81 81 Set the system to use DHCP. This requires an DHCP server.
82 82

266 269
267 270 ## Understanding the script
268 271 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:
269 272
270 273 | Script | Description |
271 274 | --- | --- |
272 275 | `10-bootstrap.sh` | Debootstrap basic system |
273 276 | `11-apt.sh` | Setup APT repositories |
274 277 | `12-locale.sh` | Setup Locales and keyboard settings |
275 278 | `13-kernel.sh` | Build and install RPi2/3 Kernel |
276 279 | `20-networking.sh` | Setup Networking |
277 280 | `21-firewall.sh` | Setup Firewall |
278 281 | `30-security.sh` | Setup Users and Security settings |
279 282 | `31-logging.sh` | Setup Logging |
280 283 | `41-uboot.sh` | Build and Setup U-Boot |
281 284 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
282 285 | `50-firstboot.sh` | First boot actions |
283 286 | `99-reduce.sh` | Reduce the disk space usage |
284 287
285 288 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.
286 289
287 290 | Directory | Description |
288 291 | --- | --- |
289 292 | `apt` | APT management configuration files |
290 293 | `boot` | Boot and RPi2/3 configuration files |
291 294 | `dpkg` | Package Manager configuration |
292 295 | `etc` | Configuration files and rc scripts |
293 296 | `firstboot` | Scripts that get executed on first boot |
294 297 | `initramfs` | Initramfs scripts |
295 298 | `iptables` | Firewall configuration files |
296 299 | `locales` | Locales configuration |
297 300 | `modules` | Kernel Modules configuration |
298 301 | `mount` | Fstab configuration |
299 302 | `network` | Networking configuration files |
300 303 | `sysctl.d` | Swapping and Network Hardening configuration |
301 304 | `xorg` | fbturbo Xorg driver configuration |
302 305
303 306 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`.
304 307
305 308 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
306 309
307 310 ## Logging of the bootstrapping process
308 311 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:
309 312
310 313 ```shell
311 314 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
312 315 ```
313 316
314 317 ## Flashing the image file
315 318 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`.
316 319
317 320 #####Flashing examples:
318 321 ```shell
319 322 bmaptool copy ./images/jessie/2015-12-13-debian-jessie.img /dev/mmcblk0
320 323 dd bs=4M if=./images/jessie/2015-12-13-debian-jessie.img of=/dev/mmcblk0
321 324 ```
322 325 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
323 326 ```shell
324 327 bmaptool copy ./images/jessie/2015-12-13-debian-jessie-frmw.img /dev/mmcblk0
325 328 bmaptool copy ./images/jessie/2015-12-13-debian-jessie-root.img /dev/sdc
326 329 ```
