1 1 # rpi2-gen-image
2 2 ## Introduction
3 3 `rpi2-gen-image.sh` is an advanced Debian Linux bootstrapping shell script for generating Debian OS images for the Raspberry 2 (RPi2) computer. The script at this time only supports the bootstrapping of the current stable Debian 8 "jessie" release.
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 `rpi2-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 `rpi2-gen-image.sh` script.
12 12
13 13 #####Command-line examples:
14 14 ```shell
15 15 ENABLE_UBOOT=true ./rpi2-gen-image.sh
16 16 ENABLE_CONSOLE=false ENABLE_IPV6=false ./rpi2-gen-image.sh
17 17 ENABLE_WM=xfce4 ENABLE_FBTURBO=true ENABLE_MINBASE=true ./rpi2-gen-image.sh
18 18 ENABLE_HARDNET=true ENABLE_IPTABLES=true /rpi2-gen-image.sh
19 19 APT_SERVER=ftp.de.debian.org APT_PROXY="http://127.0.0.1:3142/" ./rpi2-gen-image.sh
20 20 ENABLE_MINBASE=true ./rpi2-gen-image.sh
21 21 BUILD_KERNEL=true ENABLE_MINBASE=true ENABLE_IPV6=false ./rpi2-gen-image.sh
22 22 BUILD_KERNEL=true KERNELSRC_DIR=/tmp/linux ./rpi2-gen-image.sh
23 23 ENABLE_MINBASE=true ENABLE_REDUCE=true ENABLE_MINGPU=true BUILD_KERNEL=true ./rpi2-gen-image.sh
24 24 ENABLE_CRYPTFS=true CRYPTFS_PASSWORD=changeme EXPANDROOT=false ENABLE_MINBASE=true ENABLE_REDUCE=true ENABLE_MINGPU=true BUILD_KERNEL=true ./rpi2-gen-image.sh
25 25 ```
26 26
27 27 #### APT settings:
28 28 ##### `APT_SERVER`="ftp.debian.org"
29 29 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.
30 30
31 31 ##### `APT_PROXY`=""
32 32 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.
33 33
34 34 ##### `APT_INCLUDES`=""
35 35 A comma separated list of additional packages to be installed during bootstrapping.
36 36
37 37 #### General system settings:
38 38 ##### `HOSTNAME`="rpi2-jessie"
39 39 Set system host name. It's recommended that the host name is unique in the corresponding subnet.
40 40
41 41 ##### `PASSWORD`="raspberry"
42 42 Set system `root` password. The same password is used for the created user `pi`. It's **STRONGLY** recommended that you choose a custom password.
43 43
44 44 ##### `DEFLOCAL`="en_US.UTF-8"
45 45 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`.
46 46
47 47 ##### `TIMEZONE`="Europe/Berlin"
48 48 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.
49 49
50 50 ##### `EXPANDROOT`=true
51 51 Expand the root partition and filesystem automatically on first boot.
52 52
53 53 #### Keyboard settings:
54 54 These options are used to configure keyboard layout in `/etc/default/keyboard` for console and Xorg. These settings can also be changed inside the running OS using the `dpkg-reconfigure keyboard-configuration` command.
55 55
56 56 ##### `XKB_MODEL`=""
57 57 Set the name of the model of your keyboard type.
58 58
59 59 ##### `XKB_LAYOUT`=""

62 62 ##### `XKB_VARIANT`=""
63 63 Set the supported variant(s) of the keyboard layout(s).
64 64
65 65 ##### `XKB_OPTIONS`=""
66 66 Set extra xkb configuration options.
67 67
68 68 #### Networking settings (DHCP):
69 69 This parameter is used to set up networking auto configuration in `/etc/systemd/network/eth.network`.
70 70
71 71 #####`ENABLE_DHCP`=true
72 72 Set the system to use DHCP. This requires an DHCP server.
73 73
74 74 #### Networking settings (static):
75 75 These parameters are used to set up a static networking configuration in /etc/systemd/network/eth.network. The following static networking parameters are only supported if `ENABLE_DHCP` was set to `false`.
76 76
77 77 #####`NET_ADDRESS`=""
78 78 Set a static IPv4 or IPv6 address and its prefix, separated by "/", eg. "192.169.0.3/24".
79 79
80 80 #####`NET_GATEWAY`=""
81 81 Set the IP address for the default gateway.
82 82

97 97
98 98 #### Basic system features:
99 99 ##### `ENABLE_CONSOLE`=true
100 100 Enable serial console interface. Recommended if no monitor or keyboard is connected to the RPi2. In case of problems fe. if the network (auto) configuration failed - the serial console can be used to access the system.
101 101
102 102 ##### `ENABLE_IPV6`=true
103 103 Enable IPv6 support. The network interface configuration is managed via systemd-networkd.
104 104
105 105 ##### `ENABLE_SSHD`=true
106 106 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.
107 107
108 ##### `ENABLE_NONFREE`=false
109 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.
110

248 251
249 252 ## Understanding the script
250 253 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:
251 254
252 255 | Script | Description |
253 256 | --- | --- |
254 257 | `10-bootstrap.sh` | Debootstrap basic system |
255 258 | `11-apt.sh` | Setup APT repositories |
256 259 | `12-locale.sh` | Setup Locales and keyboard settings |
257 260 | `13-kernel.sh` | Build and install RPi2 Kernel |
258 261 | `20-networking.sh` | Setup Networking |
259 262 | `21-firewall.sh` | Setup Firewall |
260 263 | `30-security.sh` | Setup Users and Security settings |
261 264 | `31-logging.sh` | Setup Logging |
262 265 | `41-uboot.sh` | Build and Setup U-Boot |
263 266 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
264 267 | `50-firstboot.sh` | First boot actions |
265 268 | `99-reduce.sh` | Reduce the disk space usage |
266 269
267 270 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.
268 271
269 272 | Directory | Description |
270 273 | --- | --- |
271 274 | `apt` | APT management configuration files |
272 275 | `boot` | Boot and RPi2 configuration files |
273 276 | `dpkg` | Package Manager configuration |
274 277 | `firstboot` | Scripts that get executed on first boot |
275 278 | `initramfs` | Initramfs scripts |
276 279 | `iptables` | Firewall configuration files |
277 280 | `locales` | Locales configuration |
278 281 | `modules` | Kernel Modules configuration |
279 282 | `mount` | Fstab configuration |
280 283 | `network` | Networking configuration files |
281 284 | `sysctl.d` | Swapping and Network Hardening configuration |
282 285 | `xorg` | fbturbo Xorg driver configuration |
283 286
284 287 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`.
285 288
286 289 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
287 290
288 291 ## Logging of the bootstrapping process
289 292 All information related to the bootstrapping process and the commands executed by the `rpi2-gen-image.sh` script can easily be saved into a logfile. The common shell command `script` can be used for this purpose:
290 293
291 294 ```shell
292 295 script -c 'APT_SERVER=ftp.de.debian.org ./rpi2-gen-image.sh' ./build.log
293 296 ```
294 297
295 298 ## Flashing the image file
296 299 After the image file was successfully created by the `rpi2-gen-image.sh` script it can be copied to the microSD card that will be used by the RPi2 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`.
297 300
298 301 #####Flashing examples:
299 302 ```shell
300 303 bmaptool copy ./images/jessie/2015-12-13-debian-jessie.img /dev/mmcblk0
301 304 dd bs=4M if=./images/jessie/2015-12-13-debian-jessie.img of=/dev/mmcblk0
302 305 ```
303 306 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
304 307 ```shell
305 308 bmaptool copy ./images/jessie/2015-12-13-debian-jessie-frmw.img /dev/mmcblk0
306 309 bmaptool copy ./images/jessie/2015-12-13-debian-jessie-root.img /dev/sdc
307 310 ```
