<title>Preconfiguration File Example</title>
9
This is a complete working example of a preconfiguration file for an automated
10
install. Its use is explained in <xref linkend="automatic-install"/>. You
11
may want to uncomment some of the lines before using the file.

<informalexample><screen>
16
#### Modifying syslinux.cfg.
18
# Edit the syslinux.cfg (or similar) file, and add parameters to the end
19
# of the append line(s) for the kernel.
21
# You'll at least want to add a parameter telling the installer where to
22
# get its preseed file from.
23
# If you're installing from USB media, use this, and put the preseed file
24
# in the toplevel directory of the USB stick.
25
# preseed/file=/hd-media/preseed
26
# If you're netbooting, use this instead:
27
# preseed/url=http://host/path/to/preseed
28
# If you're remastering a CD, you could use this:
29
# preseed/file=/cdrom/preseed
30
# Be sure to copy this file to the location you specify.
32
# While you're at it, you may want to throw a debconf/priority=critical in
33
# there, to avoid most questions even if the preseeding below misses some.
34
# And you might set the timeout to 1 in syslinux.cfg to avoid needing to hit
35
# enter to boot the installer.
37
# Language, country, and keyboard selection cannot be preseeded from a file,
38
# because the questions are asked before the preseed file can be loaded.
39
# Instead, to avoid these questions, pass some more parameters to the kernel:
41
# languagechooser/language-name=English
42
# countrychooser/shortlist=US
43
# console-keymaps-at/keymap=us
47
# d-i preseeding is inherently not secure. Nothing in the installer checks
48
# for attempts at buffer overflows or other exploits of the values of a
49
# preseed file like this one. Only use preseed files from trusted
50
# locations! To drive that home, and because it's generally useful, here's
51
# a way to run any shell command you'd like inside the installer,
54
# This first command is run as early as possible, just after
56
#d-i preseed/early_command string wget http://url/to/my.udeb -O /tmp/my.udeb ; udpkg -i /tmp/my.udeb
57
# This command is run just before the install finishes, but when there is
58
# still a usable /target directory.
59
#d-i preseed/late_command string for deb in /hd-media/*.deb; do cp $deb /target/tmp; chroot /target dpkg -i /tmp/$(basename $deb); done
60
# This command is run just as base-config is starting up.
61
#base-config base-config/early_command string echo hi mom
62
# This command is run after base-config is done, just before the login:
63
# prompt. This is a good way to install a set of packages you want, or to
64
# tweak the configuration of the system.
65
#base-config base-config/late_command string apt-get install zsh; chsh -s /bin/zsh
67
#### Network configuration.
69
# Of course, this won't work if you're loading your preseed file from the
70
# network! But it's great if you're booting from CD or USB stick. You can
71
# also pass network config parameters in on the kernel params if you are
72
# loading preseed files from the network.
74
# netcfg will choose an interface that has link if possible. This makes it
75
# skip displaying a list if there is more than one interface.
76
d-i netcfg/choose_interface select auto
78
# If you prefer to configure the network manually, here's how:
79
#d-i netcfg/disable_dhcp boolean true
80
#d-i netcfg/get_nameservers string 192.168.1.1
81
#d-i netcfg/get_ipaddress string 192.168.1.42
82
#d-i netcfg/get_netmask string 255.255.255.0
83
#d-i netcfg/get_gateway string 192.168.1.1
84
#d-i netcfg/confirm_static boolean true
86
# Note that any hostname and domain names assigned from dhcp take
87
# precidence over values set here. However, setting the values still
88
# prevents the questions from being shown even if values come from dhcp.
89
d-i netcfg/get_hostname string unassigned-hostname
90
d-i netcfg/get_domain string unassigned-domain
92
# Disable that annoying WEP key dialog.
93
d-i netcfg/wireless_wep string
94
# The wacky dhcp hostname that some ISPs use as a password of sorts.
95
#d-i netcfg/dhcp_hostname string radish
99
d-i mirror/country string enter information manually
100
d-i mirror/http/hostname string http.us.debian.org
101
d-i mirror/http/directory string /debian
102
d-i mirror/suite string testing
103
d-i mirror/http/proxy string
107
# If the system has free space you can choose to only partition that space.
108
#d-i partman-auto/init_automatically_partition select Use the largest continuous free space
109
# Alternatively, you can specify a disk to partition. The device name can
110
# be given in either devfs or traditional non-devfs format.
111
# For example, to use the first disk devfs knows of:
112
d-i partman-auto/disk string /dev/discs/disc0/disc
114
# You can choose from any of the predefined partitioning recipes:
115
d-i partman-auto/choose_recipe select All files in one partition (recommended for new users)
116
#d-i partman-auto/choose_recipe select Desktop machine
117
#d-i partman-auto/choose_recipe select Multi-user workstation
118
# Or provide a recipe of your own...
119
# The recipe format is documented in the file devel/partman-auto-recipe.txt.
120
# If you have a way to get a recipe file into the d-i environment, you can
122
#d-i partman-auto/expert_recipe_file string /hd-media/recipe
123
# If not, you can put an entire recipe in one line. This example creates
124
# a small /boot partition, suitable swap, and uses the rest of the space
125
# for the root partition:
126
#d-i partman-auto/expert_recipe string boot-root :: 20 50 100 ext3 $primary{ } $bootable{ } method{ format } format{ } use_filesystem{ } filesystem{ ext3 } mountpoint{ /boot } . 500 10000 1000000000 ext3 method{ format } format{ } use_filesystem{ } filesystem{ ext3 } mountpoint{ / } . 64 512 300% linux-swap method{ swap } format{ } .
127
# For reference, here is that same recipe in a more readable form:
130
# $primary{ } $bootable{ }
131
# method{ format } format{ }
132
# use_filesystem{ } filesystem{ ext3 }
133
# mountpoint{ /boot }
135
# 500 10000 1000000000 ext3
136
# method{ format } format{ }
137
# use_filesystem{ } filesystem{ ext3 }
140
# 64 512 300% linux-swap
141
# method{ swap } format{ }
144
# This makes partman automatically partition without confirmation.
145
d-i partman/choose_partition select Finish partitioning and write changes to disk
146
d-i partman/confirm boolean true
148
#### Boot loader installation.
150
# Grub is the default boot loader (for x86). If you want lilo installed
151
# instead, uncomment this:
152
#d-i grub-installer/skip boolean true
154
# This is fairly safe to set, it makes grub install automatically to the MBR
155
# if no other operating system is detected on the machine.
156
d-i grub-installer/only_debian boolean true
157
# This one makes grub-installer install to the MBR if if finds some other OS
158
# too, which is less safe as it might not be able to boot that other OS.
159
d-i grub-installer/with_other_os boolean true
160
# Alternatively, if you want to install to a location other than the mbr,
161
# uncomment and edit these lines:
162
#d-i grub-installer/bootdev string (hd0,0)
163
#d-i grub-installer/only-debian boolean false
164
#d-i grub-installer/with_other_os boolean false
166
##### Finishing up the first stage install.
168
# Avoid that last message about the install being complete.
169
d-i finish-install/reboot_in_progress note
172
##### Preseeding base-config.
173
# XXX: Note that most of this will not work right until base-config 2.40.4
176
# Avoid the intorductory message.
177
base-config base-config/intro note
179
# Avoid the final message.
180
base-config base-config/login note
182
# If you installed a display manager, but don't want to start it immediately
183
# after base-config finishes.

#base-config base-config/start-display-manager boolean false
186
###### Time zone setup.
188
# Controls whether or not the hardware clock is set to GMT.
189
base-config tzconfig/gmt boolean true
191
# If you told the installer that you're in the United States, then you
192
# can set the time zone using this variable.
193
# (Choices are: Eastern, Central, Mountain, Pacific, Alaska, Hawaii,
194
# Aleutian, Arizona East-Indiana, Indiana-Starke, Michigan, Samoa, other)
195
base-config tzconfig/choose_country_zone/US select Eastern
196
# If you told it you're in Canada.
197

198
# East-Saskatchewan, Saskatchewan, Mountain, Pacific, Yukon, other)
199
base-config tzconfig/choose_country_zone/CA select Eastern
200
# If you told it you're in Brazil. (Choices are: East, West, Acre,
202
base-config tzconfig/choose_country_zone/BR select East
203
# Many countries have only one time zone. If you told the installer you're
204
# in one of those countries, you can choose its standard time zone via this
206
base-config tzconfig/choose_country_zone_single boolean true
207
# This question is asked as a fallback for countries other than those
208
# listed above, which have more than one time zone. You can preseed one of
209
# the time zones, or "other".
210
#base-config tzconfig/choose_country_zone_multiple select
212
###### Account setup.
214
# To preseed the root password, you have to put it in the clear in this
215
# file. That is not a very good idea, use caution!
216
#passwd passwd/root-password password r00tme
217
#passwd passwd/root-password-again password r00tme
219
# If you want to skip creation of a normal user account.
220
#passwd passwd/make-user boolean false
221
# Alternatively, you can preseed the user's name. Note that the username
222
# will be derived from this; it cannot be overridden currently. The
223
# username will be the (lowercase) first name of the full name.
224
#passwd passwd/user-fullname string Debian User
225
#passwd passwd/username string
226
# And their password, but use caution!
227
#passwd passwd/user-password password insecure
228
#passwd passwd/user-password-again password insecure
232
# This question controls what source the second stage installation uses
233
# for packages. Choices are cdrom, http, ftp, filesystem, edit sources list
235
base-config apt-setup/uri_type select http
237
# If you choose ftp or http, you'll be asked for a country and a mirror.

#base-config apt-setup/non-free boolean true
246
#base-config apt-setup/contrib boolean true
248
# Do enable security updates.
249
base-config apt-setup/security-updates boolean true
251
###### Package selection.
253
# You can choose to install any combination of tasks that are available.
254
# Available tasks as of this writing include: Desktop environment,
255
# Web server, Print server, DNS server, File server, Mail server,
256
# SQL database, manual package selection. The last of those will run
257
# aptitude. You can also choose to install no tasks, and force the
258
# installation of a set of packages in some other way.
259
# XXX: this will not work until tasksel 2.12 is available
260
tasksel tasksel/first multiselect Desktop environment
261
#tasksel tasksel/first multiselect Web server, Mail server, DNS server
263
###### Mailer configuration.
265
# During a normal install, exim asks only two questions. Here's how to
266
# avoid even those. More complicated preseeding is possible.
267
exim4-config exim4/dc_eximconfig_configtype select no configuration at this time
268
# It's a good idea to set this to whatever user account you choose to
269
# create. Leaving the value blank results in postmaster mail going to
271
exim4-config exim4/dc_postmaster string
273
###### X Configuration.
275
# Preseeding Debian's X config is possible, but you probably need to know
276
# some details about the video hardware of the machine, since Debian's X
277
# configurator does not do fully automatic configuration of everything.
279
# X can detect the right driver for some cards, but if you're preseeding,
280
# you override whatever it chooses. Still, vesa will work most places.
281
#xserver-xfree86 xserver-xfree86/config/device/driver select vesa
283
# A caveat with mouse autodetection is that if it fails, X will retry it
284
# over and over. So if it's preseeded to be done, there is a possibility of
285
# an infinite loop if the mouse is not autodetected.
286
#xserver-xfree86 xserver-xfree86/autodetect_mouse boolean true
288
# Monitor autodetection is recommended.

#xserver-xfree86 xserver-xfree86/config/monitor/lcd boolean true
292
# X has three configuration paths for the monitor. Here's how to preseed
293
# the "medium" path, which is always available. The "simple" path may not
294
# be available, and the "advanced" path asks too many questions.
295
xserver-xfree86 xserver-xfree86/config/monitor/selection-method select medium
296
xserver-xfree86 xserver-xfree86/config/monitor/mode-list select 1024x768 @ 60 Hz
298
###### Everything else.
300
# Depending on what software you choose to install, or if things go wrong
301
# during the installation process, it's possible that other questions may
302
# be asked. You can preseed those too, of course. To get a list of every
303
# possible question that could be asked during an install, do an
304
# installation, and then run these commands:
305
# debconf-get-selections --installer > file
306
# debconf-get-selections >> file
308
# If you like, you can include other preseed files into this one.
309
# Any settings in those files will override pre-existing settings from this
310
# file. More that one file can be listed, separated by spaces; all will be
311
# loaded. The included files can have preseed/include directives of their
312
# own as well. Note that if the filenames are relative, they are taken from
313
# the same directory as the preseed file that includes them.
314
#d-i preseed/include string x.cfg
315
# More flexably, this runs a shell command and if it outputs the names of
316
# preseed files, includes those files. For example, to switch configs based
317
# on a particular usb storage device (in this case, a built-in card reader):
318
#d-i preseed/include_command string if $(grep -q "GUID: 0aec3050aec305000001a003" /proc/scsi/usb-storage-*/*); then echo kraken.cfg; else echo otherusb.cfg; fi
