镜像生成器
映像生成器 是一个创建自定义固件的预编译环境，可以在现有固件的基础编辑创建镜像。
使用映像生成器的原因：
- 创建最小化镜像如去除WEB界面
- 软件包直接嵌入squashfs，减少目标平台的空间需求
- 配置文件直接嵌入squashfs作为预配置
下载
ImageBuilder随着OpenWrt Kamikaze神风8.09.2版本中，并就在服务器上提供下载。
- 浏览OpenWrt下载目录
http://kamikaze.openwrt.org/8.09.2/
- 点击你路由器的架构, 例如brcm-2.4 架构的WRT54GL映像
- 下载ImageBuilder存档。使用 i686在32位系统或x86_64 基于64位的系统
- 提取档案和目录更改到ImageBuilder
$ wget http://kamikaze.openwrt.org/...-for-Linux-i686.tar.bz2
$ tar -xjf OpenWrt-ImageBuilder-brcm-2.4-for-Linux-i686.tar.bz2
$ cd OpenWrt-ImageBuilder-brcm-2.4-for-Linux-i686/ |
用法
The make image command will create a minimal image with just essential packages included, the behaviour can be controlled with three variables passed as arguments:
PROFILE- specifies the target image to buildPACKAGES- a list of packages to embed into the imageFILES- directory with custom files to include
见下一章节的阐释。
After the make command is finished, the generated images are stored in the bin directory.
$ ls bin/
md5sums openwrt-wrt350n_v1-squashfs.bin
openwrt-brcm-2.4-squashfs.trx openwrt-wrt54g-squashfs.bin

概况
Run make info to obtain a list of defined profiles:
$ make info
Current Target: "brcm-2.4"
Default Packages: base-files libgcc … kmod-switch kmod-diag nvram
Available Profiles:
Broadcom:
Generic, Broadcom WiFi (default)
Packages: kmod-brcm-wl wlc nas kmod-wlcompat
BroadcomMimo:
Generic, Broadcom WiFi (MIMO)
Packages: kmod-brcm-wl-mimo wlc nas kmod-wlcompat
None:
Generic, No WiFi
Packages:
USBGeneric:

Packages: kmod-brcm-wl kmod-usb-core kmod-usb-ohci kmod-usb2 …
WL500G:
ASUS WL-500g

WRT54G3G:
Linksys WRT54G3G
Packages: kmod-brcm-wl kmod-usb-core kmod-usb-ohci kmod-usb2 … |
… and pass the appropriate profile to the make command:
$ make image PROFILE=WL500GP |
软件包
The PACKAGES variable specifies a list of packages to include when building an image. If a name is prefixed with - then the corresponding package will be excluded from the image.
$ make image PROFILE=WL500GP PACKAGES="nano openvpn -ppp -ppp-mod-pppoe" |
Tip贴士: 查看当前已安装的软件包列表可以使用如下命令:
root@OpenWrt:~# echo `opkg list_installed | awk '{ print $1 }'` |
文件
A directory with custom files to add can be specified using the FILES variable. Custom files will replace default ones if necessary.
$ mkdir -p files/etc/config
$ scp root@192.168.1.1:/etc/config/network files/etc/config/
$ scp root@192.168.1.1:/etc/config/wireless files/etc/config/
$ scp root@192.168.1.1:/etc/config/firewall files/etc/config/
$ make image PROFILE=WL500GP PACKAGES="nano openvpn -ppp -ppp-mod-pppoe" FILES=files/ |

清理临时文件
要清理建立和生成映像时的临时文件，请使用make clean 命令。
