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 dosfstools rsync bmap-tools whois git-core```
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 ```
23 23
24 24 #### APT settings:
25 25 ##### `APT_SERVER`="ftp.debian.org"
26 26 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.
27 27
28 28 ##### `APT_PROXY`=""
29 29 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.
30 30
31 31 ##### `APT_INCLUDES`=""
32 32 A comma seperated list of additional packages to be installed during bootstrapping.
33 33
34 34 #### General system settings:
35 35 ##### `HOSTNAME`="rpi2-jessie"
36 36 Set system host name. It's recommended that the host name is unique in the corresponding subnet.
37 37
38 38 ##### `PASSWORD`="raspberry"
39 39 Set system `root` password. The same password is used for the created user `pi`. It's **STRONGLY** recommended that you choose a custom password.
40 40
41 41 ##### `DEFLOCAL`="en_US.UTF-8"
42 42 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`.
43 43
44 44 ##### `TIMEZONE`="Europe/Berlin"
45 45 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.
46 46
47 47 ##### `EXPANDROOT`=true
48 48 Expand the root partition and filesystem automatically on first boot.
49 49
50 50 #### Keyboard settings:
51 51 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.
52 52
53 53 ##### `XKB_MODEL`=""
54 54 Set the name of the model of your keyboard type.
55 55
56 56 ##### `XKB_LAYOUT`=""
57 57 Set the supported keyboard layout(s).
58 58
59 59 ##### `XKB_VARIANT`=""
60 60 Set the supported variant(s) of the keyboard layout(s).
61 61
62 62 ##### `XKB_OPTIONS`=""
63 63 Set extra xkb configuration options.
64 64
65 65 #### Networking settings (DHCP):
66 66 This setting is used to set up networking auto configuration in `/etc/systemd/network/eth.network`.
67 67
68 68 #####`ENABLE_DHCP`=true
69 69 Set the system to use DHCP. This requires an DHCP server.
70 70
71 71 #### Networking settings (static):
72 72 These settings are used to set up a static networking configuration in /etc/systemd/network/eth.network. The following static networking settings are only supported if `ENABLE_DHCP` was set to `false`.
73 73
74 74 #####`NET_ADDRESS`=""
75 75 Set a static IPv4 or IPv6 address and its prefix, separated by "/", eg. "192.169.0.3/24".
76 76
77 77 #####`NET_GATEWAY`=""
78 78 Set the IP address for the default gateway.
79 79
80 80 #####`NET_DNS_1`=""
81 81 Set the IP address for the first DNS server.
82 82
83 83 #####`NET_DNS_2`=""
84 84 Set the IP address for the second DNS server.
85 85
86 86 #####`NET_DNS_DOMAINS`=""
87 87 Set the default DNS search domains to use for non fully qualified host names.
88 88
89 89 #####`NET_NTP_1`=""
90 90 Set the IP address for the first NTP server.
91 91
92 92 #####`NET_NTP_2`=""
93 93 Set the IP address for the second NTP server.
94 94
95 95 #### Basic system features:
96 96 ##### `ENABLE_CONSOLE`=true
97 97 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.
98 98
99 99 ##### `ENABLE_IPV6`=true
100 100 Enable IPv6 support. The network interface configuration is managed via systemd-networkd.
101 101
102 102 ##### `ENABLE_SSHD`=true
103 103 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.
104 104
105 105 ##### `ENABLE_RSYSLOG`=true
106 106 If set to false, disable and uninstall rsyslog (so logs will be available only
107 107 in journal files)
108 108
109 109 ##### `ENABLE_SOUND`=true
110 110 Enable sound hardware and install Advanced Linux Sound Architecture.
111 111
112 112 ##### `ENABLE_HWRANDOM`=true
113 113 Enable Hardware Random Number Generator. Strong random numbers are important for most network based communications that use encryption. It's recommended to be enabled.
114 114
115 115 ##### `ENABLE_MINGPU`=false
116 116 Minimize the amount of shared memory reserved for the GPU. It doesn't seem to be possible to fully disable the GPU.
117 117
118 118 ##### `ENABLE_DBUS`=true
119 119 Install and enable D-Bus message bus. Please note that systemd should work without D-bus but it's recommended to be enabled.
120 120
121 121 ##### `ENABLE_XORG`=false
122 122 Install Xorg open-source X Window System.
123 123
124 124 ##### `ENABLE_WM`=""
125 125 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`.
126 126
127 127 #### Advanced system features:
128 128 ##### `ENABLE_MINBASE`=false
129 129 Use debootstrap script variant `minbase` which only includes essential packages and apt. This will reduce the disk usage by about 65 MB.
130 130
131 131 ##### `ENABLE_UBOOT`=false
132 132 Replace default RPi2 second stage bootloader (bootcode.bin) with U-Boot bootloader. U-Boot can boot images via the network using the BOOTP/TFTP protocol.
133 133
134 134 ##### `ENABLE_FBTURBO`=false
135 135 Install and enable the hardware accelerated Xorg video driver `fbturbo`. Please note that this driver is currently limited to hardware accelerated window moving and scrolling.
136 136
137 137 ##### `ENABLE_IPTABLES`=false
138 138 Enable iptables IPv4/IPv6 firewall. Simplified ruleset: Allow all outgoing connections. Block all incoming connections except to OpenSSH service.
139 139
140 140 ##### `ENABLE_USER`=true
141 141 Create pi user with password raspberry
142 142
143 143 ##### `ENABLE_ROOT`=true
144 144 Set root user password so root login will be enabled
145 145
146 146 ##### `ENABLE_ROOT_SSH`=true
147 147 Enable password root login via SSH. May be a security risk with default
148 148 password, use only in trusted environments.
149 149
150 150 ##### `ENABLE_HARDNET`=false
151 151 Enable IPv4/IPv6 network stack hardening settings.
152 152
153 153 ##### `ENABLE_SPLITFS`=false
154 154 Enable having root partition on an USB drive by creating two image files: one for the `/boot/firmware` mount point, and another for `/`.
155 155
156 156 ##### `CHROOT_SCRIPTS`=""
157 157 Path to a directory with scripts that should be run in the chroot before the image is finally built. Every executable file in this direcory is run in lexicographical order.
158 158
159 159 #### Kernel compilation:
160 160 ##### `BUILD_KERNEL`=false
161 161 Build and install the latest RPi2 linux kernel. Currently only the default RPi2 kernel configuration is used. Detailed configuration parameters for customizing the kernel and minor bug fixes still need to get implemented. feel free to help.
162 162
163 163 ##### `KERNEL_THREADS`=1
164 164 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.
165 165
166 166 ##### `KERNEL_HEADERS`=true
167 167 Install kernel headers with built kernel.
168 168
169 ##### `KERNEL_MENUCONFIG`=false
170 Start `make menuconfig` interactive menu-driven kernel configuration. The script will continue after `make menuconfig` was terminated.
171
169 172 ##### `KERNEL_RMSRC`=true
170 173 Remove all kernel sources from the generated OS image after building.
171 174
172 175 ## Understanding the script
173 176 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:
174 177
175 178 | Script | Description |
176 179 | --- | --- |
177 180 | `10-bootstrap.sh` | Debootstrap basic system |
178 181 | `11-apt.sh` | Setup APT repositories |
179 182 | `12-locale.sh` | Setup Locales and keyboard settings |
180 183 | `13-kernel.sh` | Build and install RPi2 Kernel |
181 184 | `20-networking.sh` | Setup Networking |
182 185 | `21-firewall.sh` | Setup Firewall |
183 186 | `30-security.sh` | Setup Users and Security settings |
184 187 | `31-logging.sh` | Setup Logging |
185 | `41-uboot.sh` | Build and Setup Uboot |
188 | `41-uboot.sh` | Build and Setup U-Boot |
186 189 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
187 190 | `50-firstboot.sh` | First boot actions |
188 191
189 192 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.
190 193
191 194 | Directory | Description |
192 195 | --- | --- |
193 196 | `boot` | Boot and RPi2 configuration files |
194 197 | `firstboot` | Scripts that get executed on first boot |
195 198 | `iptables` | Firewall configuration files |
196 199 | `locales` | Locales configuration |
197 | `modprobe.d` | Kernel Module Blacklist configuration |
200 | `modules` | Kernel Modules configuration |
198 201 | `mount` | Fstab configuration |
199 202 | `network` | Networking configuration files |
200 203 | `sysctl.d` | Swapping and Network Hardening configuration |
201 204 | `xorg` | fbturbo Xorg driver configuration |
202 205
203 206 ## Logging of the bootstrapping process
204 207 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:
205 208
206 209 ```shell
207 210 script -c 'APT_SERVER=ftp.de.debian.org ./rpi2-gen-image.sh' ./build.log
208 211 ```
209 212
210 213 ## Flashing the image file
211 214 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`.
212 215
213 216 #####Flashing examples:
214 217 ```shell
215 218 bmaptool copy ./images/jessie/2015-12-13-debian-jessie.img /dev/mmcblk0
216 219 dd bs=4M if=./images/jessie/2015-12-13-debian-jessie.img of=/dev/mmcblk0
217 220 ```
218 221 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
219 222 ```shell
220 223 bmaptool copy ./images/jessie/2015-12-13-debian-jessie-frmw.img /dev/mmcblk0
221 224 bmaptool copy ./images/jessie/2015-12-13-debian-jessie-root.img /dev/sdc
222 225 ```
