CD Customization
The process of customizing or "remastering" ubuntu cd's is not espcially complex, but it is a little tedious and finicky. My knowledge of the process is also imperfect so hopefully other people will modify this page as appropriate.

The install cd has two main parts: an ?IsoLinux-derived ?OperatingSystem, which is the environment in which ?DebianInstaller runs; and a ?DebianRepository structure, which is what takes up all that space on the disk in the directories "pool" and "dists". Building a new CD involves modifications to both parts.

Modify installer behaviour using a Preseed file
When the CD boots up, a linux kernel is started and the installation tasks are initiated. The installer's default behaviour can be modified through the use of a "preseed" file, which feeds ?DebianInstaller ("d-i") answers to questions normally asked by debconf or in other contexts. If you look closely at your install cd, you'll see that certain options (e.g. "server", "expert", "oem") already have preseed files assigned to them.

So, suppose you are installing breezy on a bunch of identical computers and you already know the answers to certain questions (what country and time zone you're in, what keyboard you have, how the network should be configured, how you want to partition the hard disk, etc. etc.). You can "preseed" the answers to these questions in a very simple configuration file.

Changing isolinux.cfg to idnetify your preseed
First, though, you need to tell the kernel to look for your preseed file in the right place. The standard disk contains a directory /preseed; you should put your seed file there. You tell the isolinux kernel where to find this file by modifying its config file, located in isolinux/isolinux.cfg. My file has the following lines in it:

DEFAULT /install/vmlinuz
APPEND preseed/file=/cdrom/preseed/learnexchange.seed kbd-chooser/method=us debian-installer/locale=en_CA vga=normal initrd=/install/initrd.gz ramdisk_size=16384 root=/dev/rd/0 DEBCONF_PRIORITY=critical debconf/priority=critical rw --
DEFAULT isthe kernel loaded when I just press "enter" atthe boot prompt. APPEND contains the options passed to the kernel. preseed/file is the most important one; the next two identify my local and keyboard as Canadian; DEBCONF_PRIORITY ensures I don't see any unnecessary debconf questions.

Look carefully at your file and modify as you see fit.

Writing the preseed file
There are lots of example preseed files kicking around; here's one from the cd -- server.seed:

# Don't install usplash.
d-i base-installer/kernel/linux/extra-packages-2.6 string
# Desktop system not installed; don't waste time and disk space copying it.
d-i archive-copier/desktop-task string ubuntu-standard
d-i archive-copier/ship-task string
# Only install the standard system and language packs in the second stage.
base-config base-config/package-selection string ~tubuntu-standard
base-config base-config/language-pack-patterns string language-pack-$LL
# No language support packages.
base-config base-config/install-language-support boolean false
first notice the format. There are 4 fields:

identity of the program which will pick up this command

name of the variable whose value will be passed

variable type

value of variable

two important notes: currently, d-i expects there to be exactly one space between variable type and variable value; and the version of d-i used in breezy does not allow lines to be broken by the '\' character (newer versions do allow this).

I recommend starting with someone else' s preseed file and modifying it -- there's one available at [[ http://archive.ubuntulinux.org/ubuntu/d ... pcs01.html ]]. If you can't find what you're looking for, try executinghte following commands:

debconf-get-selections --installer > somefile.txt
debconf-get-selections >> somefile.txt
This will output a list of all debconf options you've chosen throughout your install; the file will be pretty long and not really suitable for inclusion on an install disk. in particular, NOTE: debconf-get-selections prints 2 spaces between variable type and variable value. You'll need to change that before putting such a file on a disk.

If you want to instruct d-i to install extra packages, or to install only a minimal set you need to change the "base-config base-config/package-selection " directive in the preseed. I wanted to add support for Bengali and tamil, so I used this line:

base-config base-config/package-selection string ~tubuntu-standard|~tubuntu-desktop|language-pack-gnome-bn|language-support-bn|language-pack-bn|language-support-bn|language-support-ta|language-pack-ta|language-pack-gnome-ta

Modify pool structure to include/delete packages
Probably the main reason to build your own install cd's is to modify which packages are installed; in particular you may want to add some packages to the CD. There are several ways to do this, none of which I understand fully. The easiest thing to do is to build a minimal repository structure contianing only your own extra .debs, and merge these into the cd file hierarchy before rebuilding the iso image. The tricky parts here are: generate the Packages files that debian expects to see when it encounters a repository; generate the top-level Release file debian expects; and sing the release file with gpg. Here's what I did.

. designate a file directory as your staging area; in that directory,

mkdir -p dists/breezy/extras/binary-i386 pool/extras/ isolinux preseed

Put your modified isolinux.cfg in isolinux/, and your preseed file in preseed/.

. put all the extra debs you need on your cd into pool/extras/. You will also need to include a new version of ubuntu-keyring, which I'll explain about in a second.

. in a text editor or some other way make a new file dists/breezy/extras/binary-i386/Release with the following content:

Archive: breezy
Version: 5.10
Component: extras
Origin: Ubuntu
Label: Ubuntu
Architecture: i386
. merge your changes into the cd thusly:

mount your "clean" downloaded iso: mount /path/to/iso /some/mountpoint/ -o loop

b. copy all the files to a directory somewhere (you'll need a gigabyte or two off space); I use rsync: sudo rsync -azvb --delete --backup-dir=/yeowe/usr/cdbuilder/old/ $MOUNT $BUILD (where $MOUNT isthe mountpoint, $BUILD is the location of the extracted contents)

c. This is important. In just a minute we will generate the packages file and the top-level release file using the apt-ftparchive tool. Then we will need to sign the release file using a gpg key. The install system will then check the signature againstthe public keys held in the package ubuntu-keyring. But your signature isn't in that keyring. SO you need to make a new version of the ubuntu-keyring package. This is actually really easy, but it took me forever to do it right. So here's the necessary code:

apt-get source ubuntu-keyring
cd ubuntu-keyring--2005.01.11/keyring
gpg --import < ubuntu-archive-keyring.gpg
gpg --list-keys "Your Name"
gpg --export FBB75451 437D05B5 YOURKEYID > ubuntu-archive-keyring.gpg
cd ..
dpkg-buildpackage -rfakeroot -m"Your Name <your.email@your.host>
cp ubuntu-keyring*deb $BUILD/pool/extras/
ok -- what we've done here is import the 2 ubuntu keys into your main keyring, then exported them along with your own key into a replacement keyring. "YOURKEYID" should be replaced with the 8-digit hexadecimal code that gpg tells you when you do the --list-keys command above. And really, the best policy would be to do all that first, and copy a version into your $STAGE file structure so that you have it permanently available.

. Now use apt-ftparchive to make the Packages and Release files:

sudo apt-ftparchive packages $BUILD/pool/extras/ > $BUILD/dists/breezy/extras/binary-i386/Packages

sudo apt-ftparchive -c $APTCONF release $BUILD/dists/breezy > $BUILD/dists/breezy/Release
apt-conf is a file somewhere that looks about like this:

APT::FTPArchive::Release::Origin "Ubuntu";
APT::FTPArchive::Release::Label "Ubuntu";
APT::FTPArchive::Release::Suite "breezy";
APT::FTPArchive::Release::Version "5.10";
APT::FTPArchive::Release::Codename "breezy";
APT::FTPArchive::Release::Architectures "i386";
APT::FTPArchive::Release::Components "main restricted extras";
APT::FTPArchive::Release::Description "Ubuntu Breezy";
sign the Release file with gpg: sudo gpg --output $BUILD/dists/breezy/Release.gpg -ba $BUILD/dists/breezy/Release

. now you can build the iso file:

sudo mkisofs -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -J -hide-rr-moved -o $IMAGE -R $BUILD/

$IMAGE is just the location of your iso image.

. finally, burn your cd using cdrecord:

sudo nice -18 cdrecord dev=ATA:1,1,0 speed=12 --blank=fast -v -gracetime=2 -tao $IMAGE that will burn the image on the second cd drive; if your cd-burner is the first or only cd-drive, change dev argument to 1,0,0. I strongly recommend using rewritable media -- I've burned a LOT of coasters on this project.

OK, that should do it! If anyone's interested, I've written a little script (very simple) to mostly-automate this process. I'll just include it here I guess:

#!/bin/bash
# usage
# update-learningexchange.sh kubuntu|ubuntu|xubuntu

# a very primitive script with no structure of controls etc
# no default behaviour, etc etc
# all ofthis should be trivial to implement but my
# bash syntax sucks
# obvious thing to do would be to conver to python
# & add a simple gtk front end too
# but I'm rushed at the moment

# Notes;Bugs:
# REMEMBER: this absolutely will not work if you haven't built a new version of ubuntu-keyring
# package & included that in $STAGE/pool/extras/! You do that thusly:
# apt-get source ubuntu-keyring

这儿再贴一次吧

定制Ubuntu安装CD

定制 CD

定制 Ubuntu CD 的过程并不复杂,但是她有一些繁琐和过分讲究。我对这过程所知并不完美,所以希望谁谁可以适当修改。

这安装 CD 有两个主要部分:一个 isolinux 上的操作系统,用来提供Debian安装程序的运行环境;一个 Debian 软件仓库,用来在光盘上放软件包和软件包索引。重建一个 CD 就包涵了这两部分的修改。

用 Presseed 文件修改安装行为

当这 CD 引导的时候,一个Linux内核启动和开始安装任务。这安装程序的行为可以用一个"preseed"文件来修改,这些feeds会告诉Debian安装程序("d-i")如何回答debconf或其它的问题。如果您注意看你的安装CD,您会看见这些选项(例如 "server","expert","oem")都有对应的preseed文件。

所以,假设您想在相当多的相同配置机器上安装breezy,并且您知道如何回答这些安装时候会问的问题(您所在的国家和时区,您你的键盘布局,您的网络设置,您需要如何分区等等)。您可以 "preseed" 这些问题的回答在一个和简单的配置文件里。

用 isolinux.cfg 识别您的 preseed

首先,您必须告诉内核您的 preseed 文件的位置。在标准的光盘上有个目录 /preseed ;您可以把您的 seed 文件放这儿。您要修改 isolinux/isolinux.cfg 来告诉内核哪儿可以找到这文件,在文件 isolinux/isolinux.cfg 里。我的文件里有这些行

DEFAULT /install/vmlinuz
APPEND preseed/file=/cdrom/preseed/learnexchange.seed kbd-chooser/method=us debian-installer/locale=en_CA vga=normal initrd=/install/initrd.gz ramdisk_size=16384 root=/dev/rd/0 DEBCONF_PRIORITY=critical debconf/priority=critical rw --

DEFAULT 是指我在 boot 提示符下直接按回车的情况。APPEND 包涵了要传给内核的参数。 preseed/file 是这儿最重要的;接着的那个指出我的将盘布局是加拿大;DEBCONF_PRIORITY 用来确定我不想看到不必要的 debconf 提问。

按您的情况小心修改这文件

写 preseed 文件

有很多例子可以用;这儿一个在安装盘里的 server.seed:

# Don't install usplash.
d-i base-installer/kernel/linux/extra-packages-2.6 string
# Desktop system not installed; don't waste time and disk space copying it.
d-i archive-copier/desktop-task string ubuntu-standard
d-i archive-copier/ship-task string
# Only install the standard system and language packs in the second stage.
base-config base-config/package-selection string ~tubuntu-standard
base-config base-config/language-pack-patterns string language-pack-$LL
# No language support packages.
base-config base-config/install-language-support boolean false

首先注意格式,有 4 个部分:

1.

指出是程序的那个部分
2.

命令
3.

变量类型
4.

变量值

两个要注意的地方:现在,d-i 期望有精确的类型和值;breezy 里的这个版本不支持用 \ 来处理多行(新的版本支持)。

我建议您从一些现有的 preseed 来修改,这儿有一个可以用的 [[[WWW] http://archive.ubuntulinux.org/ubuntu/d ... pcs01.html ]]. 如果您没能在这儿找到,那就试着执行这些命令

debconf-get-selections --installer > somefile.txt
debconf-get-selections >> somefile.txt

这会输出一个您在安装时候作出的选择的列表;这文件相当地长,并且实际上不那么适合用在安装盘里。特别是,NOTE: debconf-get-selections 会在类型和只之间放 2 个空格。您得在把她放在安装盘上以前修改他们。

如果您想让 d-i 安装额外的包,或一个最小的系统,您需要在 preseed 里修改 "base-config base-config/package-selection " 。 我想给她增加对孟加拉语和泰米尔语的支持,所以我用了这一行:

base-config base-config/package-selection string ~tubuntu-standard|~tubuntu-desktop|language-pack-gnome-bn|language-support-bn|language-pack-bn|language-support-bn|language-support-ta|language-pack-ta|language-pack-gnome-ta

修改 pool 目录,增加或删除一些包

或许是您主要想修改您的安装盘安装哪些包;特别是您想在 CD 里增加一些包。这有好几个方法来做到,不过我都不是完全地了解。最容易的事情是建立一个最小的仓库放您想要增加的包,再在制作光盘镜像文件以前合并到光盘文件里。这儿棘手的地方是:制作一个 Debian 本来就要安装的包;写一个更高版本的 Release 文件;并签上 GPG 。下面是我所做的。

*

. 选定一个文件目录作为您的工作空间;在这个目录里,

mkdir -p dists/breezy/extras/binary-i386 pool/extras/ isolinux preseed

把您修改过的 isolinux.cfg 放在目录 isolinux 里,把您的 preseed 文件放在目录 preseed 里。

*

. 把您需要的所有额外的包放在目录 pool/extras/ 里。您还需要包括一个新版本的 ubuntu-keyring 包,我将马上解释一下。

*

. 创建并编辑文件 dists/breezy/extras/binary-i386/Release ,写入

Archive: breezy
Version: 5.10
Component: extras
Origin: Ubuntu
Label: Ubuntu
Architecture: i386

*

. 把您做的修改合并到 CD 里

1.

挂载您下载的官方 ISO 光盘镜像文件: mount /path/to/iso /some/mountpoint/ -o loop

*

b. 把光盘里的全部文件拷贝到某个目录(您会需要 1 到 2 G 的空间);我用 rsync 来做: sudo rsync -azvb --delete --backup-dir=/yeowe/usr/cdbuilder/old/ $MOUNT $BUILD ( 这儿的 $MOUNT 是挂载点,$BUILD 是额外的包的目录)

*

c. 最重要的地方 。 我们将用 apt-ftparchive 工具来产生软件包和更高版本的 Release 文件。我们还要用 GPG 来签这个 Release 文件。安装程序会用包 ubuntu-keyring 里的公匙来检测签名。 但是您的签名不一样。所以您得建立一个新版本的 ubuntu-keyring 包。这做起来很容易

但是要确保正确无误。下面是执行的命令:

*

apt-get source ubuntu-keyring
cd ubuntu-keyring--2005.01.11/keyring
gpg --import < ubuntu-archive-keyring.gpg
gpg --list-keys "Your Name"
gpg --export FBB75451 437D05B5 YOURKEYID > ubuntu-archive-keyring.gpg
cd ..
dpkg-buildpackage -rfakeroot -m"Your Name <your.email@your.host>
cp ubuntu-keyring*deb $BUILD/pool/extras/

ok -- what we've done here is import the 2 ubuntu keys into your main keyring, then exported them along with your own key into a replacement keyring. "YOURKEYID" should be replaced with the 8-digit hexadecimal code that gpg tells you when you do the --list-keys command above. And really, the best policy would be to do all that first, and copy a version into your $STAGE file structure so that you have it permanently available.

*

. 现在就用 apt-ftparchive 来创建 Packages 和 Release 文件:
o

sudo apt-ftparchive packages $BUILD/pool/extras/ > $BUILD/dists/breezy/extras/binary-i386/Packages

sudo apt-ftparchive -c $APTCONF release $BUILD/dists/breezy > $BUILD/dists/breezy/Release

*

apt-conf 是个看起来像这样的文件:

APT::FTPArchive::Release::Origin "Ubuntu";
APT::FTPArchive::Release::Label "Ubuntu";
APT::FTPArchive::Release::Suite "breezy";
APT::FTPArchive::Release::Version "5.10";
APT::FTPArchive::Release::Codename "breezy";
APT::FTPArchive::Release::Architectures "i386";
APT::FTPArchive::Release::Components "main restricted extras";
APT::FTPArchive::Release::Description "Ubuntu Breezy";

1.

给 Release 文件签 gpg:

sudo gpg --output $BUILD/dists/breezy/Release.gpg -ba $BUILD/dists/breezy/Release

*

. 现在可以来生成光盘镜像文件:

sudo mkisofs -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -J -hide-rr-moved -o $IMAGE -R $BUILD/

*

$IMAGE 表示您的光盘镜像文件

*

. 最后,可以用 cdrecord 或其它刻录工具来刻录您的 CD 了:

sudo nice -18 cdrecord dev=ATA:1,1,0 speed=12 --blank=fast -v -gracetime=2 -tao $IMAGE

that will burn the image on the second cd drive; if your cd-burner is the first or only cd-drive, change dev argument to [ATA]1,0,0. I strongly recommend using rewritable media -- I've burned a LOT of coasters on this project.

好了,搞定! 如果谁感兴趣,我写了一个小脚本(很简单)来自动完成这个步骤。我想我正好可以放在这儿
