commit 393cde1d79128686953a89275c0841f73be53c4b
Author: Andreas B. Mundt <andi at debian.org>
Date: Wed Aug 27 10:30:01 2014 +0200
Optional PXE installation method using debian-installer and preseeding.
Switch to di-netboot-assistant to simplify PXE booting the
debian-installer.
Add an entry to the boot menu and a preseed file to run an unattended
installation of a basic Debian system. Run FAI as
preseed/late_command at the end of the installation.
Needs testing an polishing, may replace the FAI nfsroot in the long
run.

+d-i clock-setup/ntp boolean true

+
+### Partitioning
+## Partitioning example
+# 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 regular
+
+# 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 :: \
+# 40 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{ } \
+# .
+
+# 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
+
+## Partitioning using RAID
+# The method should be set to "raid".
+#d-i partman-auto/method string raid
+# Specify the disks to be partitioned. They will all get the same layout,
+# so this will only work if the disks are the same size.
+#d-i partman-auto/disk string /dev/sda /dev/sdb
+
+# Next you need to specify the physical partitions that will be used.
+#d-i partman-auto/expert_recipe string \
+# multiraid :: \
+# 1000 5000 4000 raid \
+# \$primary{ } method{ raid } \
+# . \
+# 64 512 300% raid \
+# method{ raid } \
+# . \
+# 500 10000 1000000000 raid \
+# method{ raid } \
+# .
+
+# Last you need to specify how the previously defined partitions will be
+# used in the RAID setup. Remember to use the correct partition numbers
+# for logical partitions. RAID levels 0, 1, 5, 6 and 10 are supported;
+# devices are separated using "#".
+# Parameters are:
+# <raidtype> <devcount> <sparecount> <fstype> <mountpoint> \
+# <devices> <sparedevices>
+
+#d-i partman-auto-raid/recipe string \
+# 1 2 0 ext3 / \
+# /dev/sda1#/dev/sdb1 \
+# . \
+# 1 2 0 swap - \
+# /dev/sda5#/dev/sdb5 \
+# . \
+# 0 2 0 ext3 /home \
+# /dev/sda6#/dev/sdb6 \
+# .
+
+# For additional information see the file partman-auto-raid-recipe.txt
+# included in the 'debian-installer' package or available from D-I source
+# repository.
+
+# This makes partman automatically partition without confirmation.
+d-i partman-md/confirm boolean true
+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
+
+## Controlling how partitions are mounted
+# 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
+
+### Base system installation
+# Configure APT to not install recommended packages by default. Use of this
+# option can result in an incomplete system and should only be used by very
+# experienced users.
+#d-i base-installer/install-recommends boolean false
+
+# The kernel image (meta) package to be installed; "none" can be used if no
+# kernel is to be installed.
+#d-i base-installer/kernel/image string linux-image-486
+
+### Apt setup
+# You can choose to install non-free and contrib software.
+#d-i apt-setup/non-free boolean true
+#d-i apt-setup/contrib boolean true
+# Uncomment this if you don't want to use a network mirror.
+#d-i apt-setup/use_mirror boolean false
+# Select which update services to use; define the mirrors to be used.
+# Values shown below are the normal defaults.
+#d-i apt-setup/services-select multiselect security, updates
+#d-i apt-setup/security_host string security.debian.org
+
+# Additional repositories, local[0-9] available
+#d-i apt-setup/local0/repository string \
+# http://local.server/debian stable main
+#d-i apt-setup/local0/comment string local server
+# Enable deb-src lines
+#d-i apt-setup/local0/source boolean true
+# URL to the public key of the local repository; you must provide a key or
+# apt will complain about the unauthenticated repository and so the
+# sources.list line will be left commented out
+#d-i apt-setup/local0/key string http://local.server/key
+
+# By default the installer requires that repositories be authenticated
+# using a known gpg key. This setting can be used to disable that
+# authentication. Warning: Insecure, not recommended.
+#d-i debian-installer/allow_unauthenticated boolean true
+
+### Package selection
+#tasksel tasksel/first multiselect standard, web-server
+# If the desktop task is selected, install the kde and xfce desktops
+# instead of the default gnome desktop.
+#tasksel tasksel/desktop multiselect kde, xfce
+tasksel tasksel/desktop multiselect
+
+# Individual additional packages to install
+d-i pkgsel/include string fai-client nfs-common
+# Whether to upgrade packages after debootstrap.
+# Allowed values: none, safe-upgrade, full-upgrade
+#d-i pkgsel/upgrade select none
+
+# Some versions of the installer can report back on what software you have
+# installed, and what software you use. The default is not to report back,
+# but sending reports helps the project determine what software is most
+# popular and include it on CDs.
+#popularity-contest popularity-contest/participate boolean false
+
+### Finishing up the installation
+# During installations from serial console, the regular virtual consoles
+# (VT1-VT6) are normally disabled in /etc/inittab. Uncomment the next
+# line to prevent this.
+#d-i finish-install/keep-consoles boolean true
+
+# Avoid that last message about the install being complete.
+d-i finish-install/reboot_in_progress note
+
+# This will prevent the installer from ejecting the CD during the reboot,
+# which is useful in some situations.
+#d-i cdrom-detect/eject boolean false
+
+# This is how to make the installer shutdown when finished, but not
+# reboot into the installed system.
+#d-i debian-installer/exit/halt boolean true
+# This will power off the machine instead of just halting it.
+#d-i debian-installer/exit/poweroff boolean true
+
+### Preseeding other packages
+# Depending on what software you choose to install, or if things go wrong
+# during the installation process, it's possible that other questions may
+# be asked. You can preseed those too, of course. To get a list of every
+# possible question that could be asked during an install, do an
+# installation, and then run these commands:
+# debconf-get-selections --installer > file
+# debconf-get-selections >> file
+
+
+#### Advanced options
+### Running custom commands during the installation
+# d-i preseeding is inherently not secure. Nothing in the installer checks
+# for attempts at buffer overflows or other exploits of the values of a
+# preconfiguration file like this one. Only use preconfiguration files from
+# trusted locations! To drive that home, and because it's generally useful,
+# here's a way to run any shell command you'd like inside the installer,
+# automatically.
+
+# This first command is run as early as possible, just after
+# preseeding is read.
+#d-i preseed/early_command string anna-install some-udeb
+# This command is run immediately before the partitioner starts. It may be
+# useful to apply dynamic partitioner preseeding that depends on the state
+# of the disks (which may not be visible when preseed/early_command runs).
+#d-i partman/early_command \
+# string debconf-set partman-auto/disk "\$(list-devices disk | head -n1)"
+# This command is run just before the install finishes, but when there is
+# still a usable /target directory. You can chroot to /target and use it
+# directly, or use the apt-install and in-target commands to easily install
+# packages and run commands in the target system.
+d-i preseed/late_command string mkdir -p /target/var/lib/fai/config; \\
+ in-target modprobe nfsv4; \\
