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. The script variant `minbase` (ENABLE_MINBASE=true) doesn't install `locales`.
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`=""
60 60 Set the supported keyboard layout(s).
61 61
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
83 83 #####`NET_DNS_1`=""
84 84 Set the IP address for the first DNS server.
85 85
86 86 #####`NET_DNS_2`=""
87 87 Set the IP address for the second DNS server.
88 88
89 89 #####`NET_DNS_DOMAINS`=""
90 90 Set the default DNS search domains to use for non fully qualified host names.

94 94
95 95 #####`NET_NTP_2`=""
96 96 Set the IP address for the second NTP server.
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
108 108 ##### `ENABLE_RSYSLOG`=true
109 109 If set to false, disable and uninstall rsyslog (so logs will be available only
110 110 in journal files)

To make sure all X related package dependencies are getting installed `ENABLE_XORG` will automatically get enabled if `ENABLE_WM` is used. The `rpi2-gen-image.sh` script has been tested with the following list of window managers: `blackbox`, `openbox`, `fluxbox`, `jwm`, `dwm`, `xfce4`, `awesome`.
129 129
130 130 #### Advanced system features:
131 131 ##### `ENABLE_MINBASE`=false

190 193 ##### `KERNELSRC_CLEAN`=false
191 194 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.
192 195
193 196 ##### `KERNELSRC_CONFIG`=true
194 197 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.
195 198
196 199 ##### `KERNELSRC_PREBUILT`=false
197 200 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` and `KERNEL_MENUCONFIG` are ignored and no kernel compilation tasks are performed.
198 201
202 ##### `FIRMWAREDIR`=""

241 247 Sets key size in bits. The argument has to be a multiple of 8.
242 248
243 249 ## Understanding the script
244 250 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:
245 251
246 252 | Script | Description |
247 253 | --- | --- |
248 254 | `10-bootstrap.sh` | Debootstrap basic system |
249 255 | `11-apt.sh` | Setup APT repositories |
250 256 | `12-locale.sh` | Setup Locales and keyboard settings |
251 257 | `13-kernel.sh` | Build and install RPi2 Kernel |
252 258 | `20-networking.sh` | Setup Networking |
253 259 | `21-firewall.sh` | Setup Firewall |
254 260 | `30-security.sh` | Setup Users and Security settings |
255 261 | `31-logging.sh` | Setup Logging |
256 262 | `41-uboot.sh` | Build and Setup U-Boot |
257 263 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
258 264 | `50-firstboot.sh` | First boot actions |
259 265 | `99-reduce.sh` | Reduce the disk space usage |
260 266
261 267 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.
262 268
263 269 | Directory | Description |
264 270 | --- | --- |
265 271 | `apt` | APT management configuration files |
266 272 | `boot` | Boot and RPi2 configuration files |
267 273 | `dpkg` | Package Manager configuration |
268 274 | `firstboot` | Scripts that get executed on first boot |
269 275 | `initramfs` | Initramfs scripts |
270 276 | `iptables` | Firewall configuration files |
271 277 | `locales` | Locales configuration |
272 278 | `modules` | Kernel Modules configuration |
273 279 | `mount` | Fstab configuration |
274 280 | `network` | Networking configuration files |
275 281 | `sysctl.d` | Swapping and Network Hardening configuration |
276 282 | `xorg` | fbturbo Xorg driver configuration |
277 283
284 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
286 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
287
278 288 ## Logging of the bootstrapping process
279 289 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:
280 290
281 291 ```shell
282 292 script -c 'APT_SERVER=ftp.de.debian.org ./rpi2-gen-image.sh' ./build.log
283 293 ```
284 294
285 295 ## Flashing the image file
286 296 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`.
287 297
288 298 #####Flashing examples:
289 299 ```shell
290 300 bmaptool copy ./images/jessie/2015-12-13-debian-jessie.img /dev/mmcblk0
291 301 dd bs=4M if=./images/jessie/2015-12-13-debian-jessie.img of=/dev/mmcblk0
292 302 ```
293 303 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
294 304 ```shell
295 305 bmaptool copy ./images/jessie/2015-12-13-debian-jessie-frmw.img /dev/mmcblk0
296 306 bmaptool copy ./images/jessie/2015-12-13-debian-jessie-root.img /dev/sdc
297 307 ```
