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.
91 91
92 92 #####`NET_NTP_1`=""

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)
111 111
112 112 ##### `ENABLE_SOUND`=true
113 113 Enable sound hardware and install Advanced Linux Sound Architecture.
114 114

117 117
118 118 ##### `ENABLE_MINGPU`=false
119 119 Minimize the amount of shared memory reserved for the GPU. It doesn't seem to be possible to fully disable the GPU.
120 120
121 121 ##### `ENABLE_DBUS`=true
122 122 Install and enable D-Bus message bus. Please note that systemd should work without D-bus but it's recommended to be enabled.
123 123
124 124 ##### `ENABLE_XORG`=false
125 125 Install Xorg open-source X Window System.
126 126
127 127 ##### `ENABLE_WM`=""
128 128 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 `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

154 154 password, use only in trusted environments.
155 155
156 156 ##### `ENABLE_HARDNET`=false
157 157 Enable IPv4/IPv6 network stack hardening settings.
158 158
159 159 ##### `ENABLE_SPLITFS`=false
160 160 Enable having root partition on an USB drive by creating two image files: one for the `/boot/firmware` mount point, and another for `/`.
161 161
162 162 ##### `CHROOT_SCRIPTS`=""

164 164
165 165 ##### `ENABLE_INITRAMFS`=false
166 166 Create an initramfs that that will be loaded during the Linux startup process. `ENABLE_INITRAMFS` will automatically get enabled if `ENABLE_CRYPTFS`=true. This parameter will be ignored if `BUILD_KERNEL`=false.
167 167
168 168 #### Kernel compilation:
169 169 ##### `BUILD_KERNEL`=false

174 174
175 175 ##### `KERNEL_THREADS`=1
176 176 Number of parallel kernel building threads. If the parameter is left untouched the script will automatically determine the number of CPU cores to set the number of parallel threads to speed the kernel compilation.
177 177
178 178 ##### `KERNEL_HEADERS`=true
179 179 Install kernel headers with built kernel.
180 180
181 181 ##### `KERNEL_MENUCONFIG`=false

189 189
190 190 ##### `KERNELSRC_CLEAN`=false
191 191 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.
192 192
193 193 ##### `KERNELSRC_CONFIG`=true
194 194 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.
195 195
196 196 ##### `KERNELSRC_PREBUILT`=false
197 197 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.
198 198
199 ##### `FIRMWAREDIR`=""
200 The directory 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.
201
199 202 #### Reduce disk usage:

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