 preseed主要包括以下内容

 、本地化

 、网络设置

 、镜像设置

 、账号设置

 、时钟与时区设置

 、分区

 、基本系统安装

 、设置apt

 、选择软件包

 、安装bootloader

 、完成安装

 、预置其他的软件包

 #书写perseed时需要注意的点

 #preconfiguration 文件格式如下

 #<owner> <question name> <question type> <value>

 #确保type与value之间只有一个空格符或者tab

 #多行的话最好是在question name后添加\，而不应该在type与value之间

 #对于debconf 变量，owner前需要加d-i

 #其二，可以通过debconf-utils软件包里面的debconf-get-selections导出debconf数据库和安装程序的cdebconf数据库到另一文件

 #debconf-get-selections --installer > file

 #debconf-get-selections >> file

 #本地化 设置 language country and locale

 #如果预置locale为en_NL在安装后系统默认的locale将是en_US.UTF-,如果想要使用en_GB.UTF-,该值需要分别进行预置

 #d-i debian-installer/language srtring en

 #d-i debian-installer/country string CH

 d-i debain-install/locale string zh_CN.UTF-

 #键盘配置，安装时只提供基本keymap，高级的需要在安装好的系统下才能使用，使用dpkg-reconfigure keyboard-configuration配置

 d-i keyboard-configuration/xkb-keymap select us

 #d-i keyboard-configuration/toggle select No toggling

 #网络设置

 #如果需要禁用网络，则如下

 #d-i netcfg/enable boolean false

 #若网络可用，则netcfg将选择一网口，如果需要跳过显示选择网卡列表，则设置自动选择

 #d-i netcfg/choose_interface select auto

 #如果想直接指定某一网口，则设置如下

 #d-i netcfg/choose_interface select eth0

 #设置链接网口的检测时间,默认时间时3秒

 #d-i netcfg/link_wait_timeout string

 #如果DHCP服务器延迟较高，可以将安装过程中DHCP设置时延变长

 #d-i netcfg/dhcp_timeout string

 #如果需要手动配置网络，则如下配置

 #d-i netcfg/disable_autoconfig boolean true

 #d-i netcfg/dhcp_failed note

 #d-i netcfg/dhcp_options select Configure network manually

 #d-i netcfg/get_nameservers string 192.168.1.1

 #d-i netcfg/get_ipaddress string 192.168.1.42

 #d-i netcfg/get_netmask string 255.255.255.0

 #d-i netcfg/get_gateway string 192.168.1.1

 #d-i netcfg/confirm_static boolean true

 #设置hostname以及domain避免问答

 #d-i netcfg/get_hostname string unassigned-hostname

 #d-i netcfg/get_domain string unassigned-domain

 #手动预置hostname

 #d-i netcfg/hostname string abc

 #non-free需要网络，可以配置其直接连接网络而无需询问

 #d-i hw-detect/load_firmware boolean true

 #需要注意的是，如果netcfg/get_netmask没有预置，netcfg将自动侦测掩码，这种情况下，为了自动安装，变量需要标记为seen，

 #同样，如果netcfg/get_gateway没有设置，netcfg将自动选择一个合适的地址。特殊情况下，可以设置netcfg/get_gateway

 #为none确定不使用网关

 #网络控制台

 #如果需要通过SSH进行远程安装，就需要确保网络console

 #d-i anna/choose_modules string network-console

 #d-i network-console/authorized_keys_url string http://10.133.5.100/ubuntu/openssh-key

 #d-i network-console/password password r00tme

 #d-i network-console/password-again password r00tme

 #镜像设置

 #镜像可用于下载安装程序的额外组件、安装基本系统以及所安装的系统建立/etc/apt/source.list

 #参数mirror/suite决定了安装号的系统使用的套件。

 #参数mirror/udev/suite决定安装程序使用的额外组件的套件。它只在组件通过网络下载病与安装时使用的initrd建立套件相匹配时才有效。

 #通常安装程序会自动安装病使用正确的值，而无需手动设置

 #如果选择FTP，则mirror/country无需设置

 #d-i mirror/protocol string ftp 如果不指出所用协议，则默认为http

 d-i mirror/country string manual

 d-i mirror/http/hostname string http.us.debian.org

 d-i mirror/http/directory string /debian

 d-i mirror/http/proxy string

 #安装套件

 #d-i mirror/suite string testing

 #d-i mirror/udev/suite string testing

 #账号设置

 #root账号的密码和普通用户的用户名和密码都可以预置。可以使用纯文本或者MD5

 #如果需要跳过root用户的创建则

 #d-i passwd/root-login boolean false

 #同样也可以跳过创建普通用户

 #d-i passwd/make-user boolean false

 #设置root密码，负责为空

 #d-i passwd/root-password password 123456st

 #d-i passwd/root-password-again password 123456st

 #同样可以用加密的MD5哈希

 #d-i passwd/root-password-crtpted password [MD5 hash]

 #创建普通账户

 #d-i passwd/user-fullname string Debian User

 #d-i passwd/username string debian

 # 普通用户密码

 #d-i passwd/user-password password insecure

 #d-i passwd/user-password-again password insecure

 # 或者用MD5

 #d-i passwd/user-password-crypted password [MD5 hash]

 # 为第一个用户以指定UID进行创建

 #d-i passwd/user-uid string

 # 将第一用户加入某一group

 #d-i passwd/user-default-groups string audio cdrom video

 passwd/root-password-crypted 和 passwd/user-password-crypted 值可以使用 “!” 作为他们的预置值。这种情况下，对应的帐号关闭。

 它常用于 root 帐号，用其他替代方法允许管理或 root 登录(例如使用 SSH key 认证或 sudo).

 下面的命令可用于生成密码的 MD5 值。

 mkpasswd -m sha-

 #时钟与时区设置

 #设置硬件时钟是否为UTC

 d-i clock-setup/utc boolean true

 #设置为某一时区

 #设置在安装过程中是否以NTP为时间基准

 d-i clock-setup/ntp boolean true

 # 使用的NTP服务器

 #d-i clock-setup/ntp-server string xxx

 #分区设置

 分区可以参考一下以下资料

 #http://www.cnblogs.com/silenceli/p/3472222.html

 #https://wiki.ubuntu.com/Enterprise/WorkstationAutoinstallPreseed

 #使用预置进行硬盘分区受限于 partman-auto 提供的支持。您可以选择使用磁盘上已有的空闲分区或者整个磁盘。磁盘的布局将取决于所使用的预定义方案，用户自定义的方案文件或预置文件包含的方案。

 #已经支持包括 RAID、LVM 和加密高级分区设置的预置，但对于非预置安装的分区仍然弹性不足。

 #下面的例子仅提供了使用方案的最基本信息。详细的内容清参考文件 partman-auto-recipe.txt 和 partman-auto-raid-recipe.txt，它们含在 debian-installer 软件包里。这两个文件也可以从 debian-installer source repository##获取。注意不同发布版支持的功能会有所改变。

 #http://anonscm.debian.org/gitweb/?p=d-i/debian-installer.git;a=tree;f=doc/devel

 # If the system has free space you can choose to only partition that space.

 # This is only honoured if partman-auto/method (below) is not set.

 #d-i partman-auto/init_automatically_partition select biggest_free

 # Alternatively, you may specify a disk to partition. If the system has only

 # one disk the installer will default to using that, but otherwise the device

 # name must be given in traditional, non-devfs format (so e.g. /dev/hda or

 # /dev/sda, and not e.g. /dev/discs/disc0/disc).

 # For example, to use the first SCSI/SATA hard disk:

 #d-i partman-auto/disk string /dev/sda

 # In addition, you'll need to specify the method to use.

 # The presently available methods are:

 # - regular: use the usual partition types for your architecture

 # - lvm: use LVM to partition the disk

 # - crypto: use LVM within an encrypted partition

 d-i partman-auto/method string lvm

 # If one of the disks that are going to be automatically partitioned

 # contains an old LVM configuration, the user will normally receive a

 # warning. This can be preseeded away...

 d-i partman-lvm/device_remove_lvm boolean true

 # The same applies to pre-existing software RAID array:

 d-i partman-md/device_remove_md boolean true

 # And the same goes for the confirmation to write the lvm partitions.

 d-i partman-lvm/confirm boolean true

 d-i partman-lvm/confirm_nooverwrite boolean true

 # You can choose one of the three predefined partitioning recipes:

 # - atomic: all files in one partition

 # - home: separate /home partition

 # - multi: separate /home, /usr, /var, and /tmp partitions

 d-i partman-auto/choose_recipe select atomic

 # Or provide a recipe of your own...

 # If you have a way to get a recipe file into the d-i environment, you can

 # just point at it.

 #d-i partman-auto/expert_recipe_file string /hd-media/recipe

 # If not, you can put an entire recipe into the preconfiguration file in one

 # (logical) line. This example creates a small /boot partition, suitable

 # swap, and uses the rest of the space for the root partition:

 #d-i partman-auto/expert_recipe string \

 # boot-root :: \

 #    ext3 \

 # $primary{ } $bootable{ } \

 # method{ format } format{ } \

 # use_filesystem{ } filesystem{ ext3 } \

 # method{ format } format{ } \

 # use_filesystem{ } filesystem{ ext3 } \

 # mountpoint{ / } \

 # . \

 #   % linux-swap \

 # method{ swap } format{ } \

 # .

 # The full recipe format is documented in the file partman-auto-recipe.txt

 # included in the 'debian-installer' package or available from D-I source

 # repository. This also documents how to specify settings such as file

 # system labels, volume group names and which physical devices to include

 # in a volume group.

 # This makes partman automatically partition without confirmation, provided

 # that you told it what to do using one of the methods above.

 d-i partman-partitioning/confirm_write_new_label boolean true

 d-i partman/choose_partition select finish

 d-i partman/confirm boolean true

 d-i partman/confirm_nooverwrite boolean true

 #其他分区方式可以查看

 #https://www.debian.org/releases/stable/i386/apbs04.html.zh-cn#ftn.idp56652848

 #分区挂载控制

 #文件系统一般使用 UUID 作为关键字挂载; 这使得在设备名变更的情况下仍然可以正常挂载。UUID

 #本身很长不容易阅读，因此，安装程序也可以依照您的意愿使用传统设备名或者指定标签(label)挂载文件系统。假如安装程序使用标签方式，那些没有标签

 #的文件系统仍然使用 UUID 方式挂载。

 #具有固定名称的设备，比如 LVM 逻辑卷，将继续使用它们自己的名字而不是 UUID 方式挂载。

 #传统设备名会根据内核在引导时发现的次序进行调整，这将导致挂载错误的文件系统。与此类似，假如您插入一个新磁盘或 USB 设备，标签也可能有冲突发生。这样系统启动后会出现一些随机的情况。

 # The default is to mount by UUID, but you can also choose "traditional" to

 # use traditional device names, or "label" to try filesystem labels before

 # falling back to UUIDs.

 #d-i partman/mount_style select uuid

 #基本系统的安装

 #本阶段的安装并没有多少东西需要预置。仅有一个与内核安装相关的问题。
