dnl OpenBSDInstallPrelude(troublesome disk types)
dnl
dnl Installation introduction.  Warns about disk geometry hell if argument
dnl is not empty.
define({:-OpenBSDInstallPrelude-:},

this document in hand and are careful to read and remember the
information which is presented to you by the install program, it
shouldn't be too much trouble.ifelse(X$1,X,,{:-

If the disks connected to your machine are $1,
it is recommended that you know their geometry, i.e. the sector size (note
that sector sizes other than 512 bytes are not currently supported), the
number of sectors per track, the number of tracks per cylinder (also known
as the number of heads), and the number of cylinders on the disk.  The
OpenBSD kernel will try to discover these parameters on its own, and if it
can it will print them at boot time.  If possible, you should use the
parameters it prints.  (You might not be able to because you're sharing your
disk with another operating system, or because your disk is old enough that
the kernel can't figure out its geometry.)-:})-:})dnl
dnl
dnl OpenBSDInstallPart2
dnl Describes the beginning of the installation process, once the
dnl installation media is ready.
define({:-OpenBSDInstallPart2-:},
{:-You should now be ready to install OpenBSD.

The following is a walk-through of the steps you will take while getting
OpenBSD installed on your hard disk.

The installation procedure is designed to gather as much information about
your system setup as possible at the beginning, so that no human interaction
is required as soon as the questions are over.

The order of these questions might be quite disconcerting if you are used to
other installation procedures, including older OpenBSD versions.

If any question has a default answer, it will be displayed in brackets ("[]")
after the question.  If you wish to stop the installation, you may hit
Control-C at any time, but if you do, you'll have to begin the installation
process again from scratch.  Using Control-Z to suspend the process may be a
better option, or at any prompt enter `!' to get a shell, from which 'exit'
will return you back to that prompt (no refresh of the prompt will occur,
though).-:})dnl
dnl
dnl OpenBSDInstallPart3(warn geometry, disk type, disk type, disk type)
dnl
dnl Describes the boot of the ramdisk, the expected disk devices
dnl names, and warns bore the reader with geometry concerns if the
dnl first argument is not empty.
dnl Describes the serial terminal setup.
define({:-OpenBSDInstallPart3-:},

	install tools what disk to install on.  If you cannot read
	the messages as they scroll by, do not worry -- you can get
	at this information later inside the install program.

dnl dot.profile
	After the kernel is done initialising, you will be asked whether
	you wish to do an "(A)utoinstall", "(I)nstall" or an "(U)pgrade".

dnl install.sub (install) hostname
{:-	The first question you will be asked is the system hostname.
	Reply with the name of the system, without any domain part.

dnl install.sub (install) donetconfig
	You will now be given an opportunity to configure the network.
	The network configuration you enter (if any) can then be used to
	do the install from another system using HTTP or FTP, and will
	also be the configuration used by the system after the installation
	is complete.

dnl XXX add a MDVLAN feature and document vlan setup
	The install program will give you a list of network interfaces you
	can configure.  For each network interface you select to configure,
	you will be asked for:

	- the symbolic host name to use (except for the first
	  interface setup, which will reuse the host name entered at the
	  beginning of the installation).

	- the IPv4 settings: address and netmask.  If the IP address
	  should be obtained from a DHCP server, simply enter ``dhcp''
	  when asked for the address.

	- the IPv6 settings (address, prefix length, and default router).
	  You may enter ``rtsol'' when asked for the address for the
	  interface to configure automatically via router solicitation
	  messages.

	After all interfaces have been configured, if there have been
	any IPv4 interfaces setup, you will be asked for the IPv4 default
	route.  This step is skipped if you only have one IPv4 interface
	setup, and it is configured with DHCP.

	The install program will also ask you for your DNS domain name,
	and the domain name servers, unless this information has
	already been obtained from a DHCP server during interface setup.

	You will also be presented with an opportunity to do more
	manual configuration.  If you accept, you will be dropped
	to a shell; when you are done, enter `exit' to return to
	the installation program.

dnl install.sub (install) askpassword root
	You will then be asked to enter the initial root password
	of the system, twice.
	Although the install program will only check that the two
	passwords match, you should make sure to use a strong password.
	As a minimum, the password should be at least eight characters
	long and a mixture of both lower and uppercase letters, numbers
	and punctuation characters.

dnl install.sub (install) questions(): sshd/ntpd
	You will then be asked whether you want to start sshd(8) by
	default, as well as ntpd(8).  If you choose to start ntpd(8),
	you will be asked for your ntp server; if you don't have any
	preferred ntp server, press enter to confirm the default

dnl install.sub (install) questions(): serial console setup
ifelse(MDSERCONS,,,{:-
	If you are installing using a serial console, and since by default,
	the OpenBSD/MACHINE installation will only start terminals on
	the primary display device, the installation program will ask you
	whether you want to also enable an additional terminal on that
	line, and will allow you to select the line speed.
-:})dnl

dnl install.sub (install) user_setup()
	You will now be given the possibility to setup a user account
	on the forthcoming system.  This user will be added to the
	`wheel' group.

	Enter the desired login name, or `n' if you do not want to
	add a user account at this point.  Valid login names are
	sequences of digits and lowercase letters, and must start
	with a lowercase letter.  If the login name matches this
	criteria, and doesn't conflict with any of the administrative
	user accounts (such as `root', `daemon' or `ftp'), you
	will be prompted with the users descriptive name, as well
	as its password, twice.
	As for the root password earlier, the install program will only
	check that the two passwords match, but you should make sure to
	use a strong password here as well.

	If you have chosen to setup a user account, and you had chosen
	to start sshd(8) on boot, you will be given the possibility to
	disable sshd(8) logins as root.
dnl install.sub (install) set_timezone
ifelse(MDTZ,,,
{:-
	You may now be given the opportunity to configure the time zone
	your system will be using (this depends on the installation
	media you are using).

	alarmed, the time zone will be configured at the end
	of the installation.

dnl install.sh ask whether to use DUIDs before the md_prep_disklabel loop
	The installation program will now tell you which disks it can
	install on, and ask you which it should use.
	Reply with the name of your root disk.

	You will the be asked if you want to use DUID notation in
	/etc/fstab, instead of traditional device names. You are strongly
	advised to use DUIDs, as they allow you to move your disks to
	different controllers, or change their bus identifiers, without
	having to modify /etc/fstab every time your configuration changes.-:})dnl

dnl
define({:-OpenBSDInstallPart5-:},
{:-	Next the disk label which defines the layout of the OpenBSD
	partitions must be set up.  Each file system you want will
	require a separate partition.

	You will be proposed a default partition layout, trying
	to set up separate partitions, disk size permitting.

	You will be given the possibility to either accept the proposed
	layout, or edit it, or create your own custom layout.  These last
	two choices will invoke the disklabel(8) interactive editor,
	allowing you to create your desired layout.

	Within the editor, you will probably start out with only the
	'c' partition of fstype 'unused' that represents the whole disk.
	This partition can not be modified.$1

	You must create partition 'a' as a native OpenBSD partition, i.e.
	one with "4.2BSD" as the fstype, to hold the root file system.$2

	In addition to partition 'a' you should create partition 'b' with
	fstype "swap", and native OpenBSD partitions to hold separate file
	systems such as /usr, /tmp, /var, and /home.

	You will need to provide a mount point for all partitions you
	{:-define-:}.  Partitions without mount points, or not of 4.2BSD fstype,
	will neither be formatted nor mounted during the installation.

	For quick help while in the interactive editor, enter '?'.  The
	`z' command (which deletes all partitions and starts with a
	clean label), the `A' command (which performs the automatic
	partition layout) and the `n' command (to change mount points)
	are of particular interest.

	Although the partitions position and size are written in exact
	sector values, you do not need a calculator to create your
	partitions!  Human-friendly units can be specified by adding `k',
	`m' or `g' after any numbers to have them converted to kilobytes,
	megabytes or gigabytes. Or you may specify a percentage of the
	disk size using `%' as the suffix.

dnl Notes for various installation methods.
dnl
define({:-OpenBSDURLInstall-:},
{:-	To install via FTP or HTTP:
		To begin an FTP or HTTP install you will need the following
		pieces of information:
		1) Proxy server URL if you are using a URL-based FTP or
		   HTTP proxy (squid, CERN FTP, Apache 1.2 or higher).
		   You need to {:-define-:} a proxy if you are behind a
		   firewall that blocks outgoing FTP or HTTP connections
		   (assuming you have a proxy available to use).
		2) The IP address (or hostname if you configured
		   DNS servers earlier in the install) of an FTP or HTTP
		   server carrying the OpenBSD OSREV distribution.
		   The installation program will try to fetch a list
		   of such servers; depending on your network settings,
		   this might fail.  If the list could be fetched, it
		   will be displayed, and you can choose an entry from
		   the list (the first entries are expected to be the
		   closest mirrors to your location).
		3) The directory holding the distribution sets.
		   The default value of pub/OpenBSD/OSREV/MACHINE
		   is almost always correct on FTP servers; for HTTP
		   servers there is no standard location for this.
		4) For FTP installs only, the login and password for the

		Unlike all other installation methods, there is no way
		to know the names of the files on tape.  Because of this,
		it is impossible to check that the files on tape match
		the machine architecture and release of OpenBSD/MACHINE.

		Moreover, since tape filenames are not known, the file
		checksums can not be verified.  Use this installation
		method only if there is no better option.

		In order to install from tape, the distribution sets to be

dnl ========== Autoinstall instructions
dnl (usually used by arch/install)
dnl
dnl OpenBSDUnattendedInstallation()dnl
define({:-OpenBSDUnattendedInstallation-:},
{:-dnl
Preparing an unattended installation of OpenBSD:
------------------------------------------------

If the installation system detects that it booted from the network,
and isn't interrupted within 5 seconds, it attempts a fully-automatic
installation.  In this mode the installer runs dhclient(8) on the
network interface the system booted from, and upon success retrieves
a response file via HTTP.  The "next-server" DHCP option specifies the
hostname part of the URL, as in "http://<next-server>/install.conf".

You can also retrieve the response file from another source, a local
disk for example.  If you wish to do that, enter the shell, retrieve
the response file, store it as /install.conf, and start the automatic
installation by leaving the shell and entering 'A' for "(A)utoinstall"
at the prompt.

The response file format is very simple.  It contains key/value pairs
separated by an equals sign '=', where the key is a substring of the
question or the plural of a thing in multiple-choice questions, and
the value is what would have been entered at the interactive prompt.
Empty lines, and lines beginning with a '#' character are ignored.

Here is a minimal response file:

  system hostname = openbsd
  # generated with: encrypt -- secret
  password for root = ${:--:}2a${:--:}06${:--:}4Q.5e2eIJYyMn2J/HTR6N.gJ4tpBsSXgYrhVnxlomfhVGHOcnu3KW
  location of sets = http

(Passwords should always be encrypted using encrypt(1), although the
installer also accepts cleartext passwords.)

The "system hostname" key above matches the following full question
asked during an interactive installation:

  System hostname? (short form, e.g. 'foo')

Take "network interfaces" for an example of a multiple-choice question,
which could be asked during an interactive installation:

  Available network interfaces: re0 re1
  Which one do you wish to configure? [re0]

In a response file, this multiple-choice question is identified by
only the ``thing'' which is available: "network interfaces" in this
case.  To configure these two interfaces the response file might
contain:

  network interfaces = re0 re1
  IPv4 address for re0 = dhcp
  IPv4 address for re1 = dhcp

While the installation is in progress the installer will redirect all
output to the file /install.log, which can also be found on the freshly
installed system after the initial reboot.  If the installation is
successful the system will reboot automatically; otherwise, you will
be dropped back into the shell where you can look at the /install.log
file or try again.

dnl XXX: do we want this?
dnl A more complete example of a response file is distributed with the
dnl OpenBSD installation sets for amd64, which is recommended to use as a
dnl starting point and reference for writing your own.

define({:-OpenBSDUpgrade-:},
{:-Warning! Upgrades to OpenBSD OSREV are currently only supported from the
immediately previous release.  The upgrade process will also work with older
releases, but might not execute some migration tasks that would be necessary
for a proper upgrade.

The best solution, whenever possible, is to backup your data and reinstall
from scratch. As a minimum, if the toolchain (the ``comp'' set) was installed,
you should remove all files within /usr/{:-include-:} before attempting to
upgrade.

To upgrade OpenBSD OSREV from a previous version, start with the general
instructions in the section "Installing OpenBSD".

Boot from $1.
When prompted, select the (U)pgrade option rather than the (I)nstall
option at the prompt in the install process.

You will be presented with a welcome message and asked if you really wish
to upgrade.

The upgrade script will ask you for the existing root partition, and
will use the existing filesystems defined in /etc/fstab to install the
new system in.  It will also use your existing network parameters.

From then, the upgrade procedure is very close to the installation
procedure described earlier in this document.  Note that the upgrade
procedure will not let you pick neither the ``etc{:--:}OSrev.tgz'' nor the
``xetc{:--:}OSrev.tgz'' sets, so as to preserve your files in `/etc' which
you are likely to have customized since a previous installation.

However, it is strongly advised that you unpack the etc{:--:}OSrev.tgz and
xetc{:--:}OSrev.tgz sets in a temporary directory and merge changes by hand, or
with the help of the sysmerge(8) helper script, since all components of
your system may not function correctly until your files in `/etc' are
updated.-:})dnl

	directory.  Otherwise, you will have to download them from one of
	the OpenBSD FTP or HTTP mirror sites, using an FTP client or a web
	browser.  In either case, take care to do "binary" transfers, since
	these are images files and any DOS cr/lf translations or Control-z
	EOF interpretations will result in corrupted transfers.
	
	You will also need to go to the "tools" directory and grab a
	copy of the rawrite.exe utility and its documentation.  This
	program is needed to correctly copy the bootable filesystem
	image to the floppy, since it's an image of a unix partition
	containing an ffs filesystem, not an MSDOS format diskette.

	Note that if you are using NT, 2000, or XP to write the

	is also available in the "tools" directory.  Grab it and

define({:-OpenBSDXferFloppyFromUNIX-:},
{:-Creating a bootable floppy disk using SunOS, Solaris or other Un*x-like
system:

	First, you will need obtain a local copy of the bootable filesystem
	image as described above.  If possible use the sha1(1) command to
	verify the checksums of the images vs. the values in the SHA256 file
	on the mirror site.

	Next, use the dd(1) utility to copy the file to the floppy drive.
	The command would likely be, under SunOS:
		dd if=floppy{:--:}OSrev.fs of=/dev/rfd0c bs=36b

	If you are using another operating system, you may have to adapt
