制作debian live CD

debian live cd工程的主页在这里：
http://live.debian.net/
所有关于制作debian live cd的资料都有。debian live cd的维基在这里：
http://wiki.debian.org/DebianLive/

以下是主要的制作过程：

1. 安装基本制作工具live-helper:

   $ aptitude install live-helper

2. 建立制作配置，生成两个目录config和scripts：

   $ lh_config --mirror-bootstrap "ftp://mirror.cpsc.ucalgary.ca/mirror/debian.org/debian/" --mirror-chroot "ftp://mirror.cpsc.ucalgary.ca/mirror/debian.org/debian/" --mirror-binary "http://ftp.debian.org/debian/" --debian-installer netinst

   头两个参数指定用于制作live CD的包源；第三个参数指定最终生成的live CD中使用的包源；参数debian-installer指定生成的live CD将包括一个debian网络安装接口；编辑配置文件config/chroot定制额外的包。例如，制作包括gnome桌面环境的live CD，可以通过修改变量LH_PACKAGES_LISTS：

   LH_PACKAGES_LISTS="gnome"

   这个变量实际上引用了live-helper预先定义的“宏”，类似于apt中pseudo包的意思。要包含具体的软件包，可以编辑变量LH_PACKAGES：

   LH_PACKAGES="gparted dosfstools ntfsprogs emacs wodim apt-spy less mplayer"

3. 配置完毕，正式生成镜像文件binary.iso：

   $ lh_build

4. 生成镜像文件后，用虚拟机测试一下：

   $ qemu -cdrom binary.iso

5. 测试满意，烧成CD：

   $ wodim binary.iso

creating a debian live cd

Above all, the debian live cd project's home is:
http://live.debian.net/
There are all about debian live cd. Another resource is its wiki:
http://wiki.debian.org/DebianLive/

The following shows the main process:

1. The basic utility bundle is live-helper:

   $ aptitude install live-helper

2. Make a configuration base in which two directories, config and scripts, are created:

   $ lh_config --mirror-bootstrap "ftp://mirror.cpsc.ucalgary.ca/mirror/debian.org/debian/" --mirror-chroot "ftp://mirror.cpsc.ucalgary.ca/mirror/debian.org/debian/" --mirror-binary "http://ftp.debian.org/debian/" --debian-installer netinst

   The first two options specify the package retrieval source for building a live CD; The third option specifies the apt source used by the final live system; option debian-installer instructs to create a live CD with debian net installer interface.User may want to include extra pakcages into the live CD, which can be done by editing the file config/chroot. For example, if a user wants to make a live CD with gnome, edit the variable LH_PACKAGES_LISTS:

   LH_PACKAGES_LISTS="gnome"

   Actually, this variable refers live-helper predefined 'macro', like the pseudo package name in APT. Another similar variable LH_PACKAGES can be used to include atom package:

   LH_PACKAGES="gparted dosfstools ntfsprogs emacs wodim apt-spy less mplayer"

3. Then build a ISO file in terms of the configuration:

   $ lh_build

4. User may want to test the ISO image:

   $ qemu -cdrom binary.iso

5. Finally, burn the ISO image:

   $ wodim binary.iso
