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 ```debootstrap debian-archive-keyring qemu-user-static binfmt-support dosfstools rsync bmap-tools whois git-core```
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`=""
93 93 Set the IP address for the first NTP server.
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.

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
132 132 Use debootstrap script variant `minbase` which only includes essential packages and apt. This will reduce the disk usage by about 65 MB.
133 133

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.

277 278 ## Logging of the bootstrapping process
278 279 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:
279 280
280 281 ```shell
281 282 script -c 'APT_SERVER=ftp.de.debian.org ./rpi2-gen-image.sh' ./build.log
282 283 ```
283 284
284 285 ## Flashing the image file
285 286 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`.
286 287
287 288 #####Flashing examples:
288 289 ```shell
289 290 bmaptool copy ./images/jessie/2015-12-13-debian-jessie.img /dev/mmcblk0
290 291 dd bs=4M if=./images/jessie/2015-12-13-debian-jessie.img of=/dev/mmcblk0
291 292 ```
292 293 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
293 294 ```shell
294 295 bmaptool copy ./images/jessie/2015-12-13-debian-jessie-frmw.img /dev/mmcblk0
295 296 bmaptool copy ./images/jessie/2015-12-13-debian-jessie-root.img /dev/sdc
296 297 ```
