Emdebian Bootstrapping
======================
Cross-building can get very confusing at times. The confusion only increases
when dealing with a chroot. This document tries to cover some of the reasons,
some of the problems and tries to provide some clarity, at least as far as how
chroots can be used in Emdebian.
There are multiple ways that Emdebian can relate to bootstrapping and chroots.
The most common method of using a chroot within Debian is pbuilder and the
pdebuild wrapper and this is the primary inspiration for using chroots in
Emdebian. Other methods revolve around QEMU or scratchbox and whilst this code
may be able to support such uses later, there are key differences in how and
why this method is separate.
EMDEBIAN PBUILDER CHROOT MODEL
==============================
The Debian pbuilder package exists to ensure package dependencies are complete
and to provide an environment to automate package building on all supported
Debian architectures without cluttering the build machine with every library
and dev package in the entire archive. This is particularly useful when
building GUI packages that can have two dozen dependencies or more. In
Emdebian, this separation between the build system packages and the chroot
packages becomes even more useful because cross-building often involves not
only installing the library and -dev package for the build architecture (e.g.
i386/amd64) but also building and installing the same library and -dev package
(with dependencies) in the TARGET architecture, e.g. arm, with apt-cross and
dpkg-cross. The chaos that could result from trying to upgrade the packages on
an Emdebian buildd system with a duplicate set of cross dependencies is truly
scary.
In the pbuilder model, an Emdebian chroot is the SAME architecture as the
buildd - i386 on i386 etc. This mimics how emdebian-tools normally work.
Packages are then downloaded, patched and cross-built for the target
architecture, just as outside the chroot. This model, the pbuilder model of an
emdebian chroot, concentrates on dependencies rather than the actual
cross-building process. Inside such a chroot, cache files are used as normal to
avoid having to run the cross-compiled code during the build.
The Emdebian chroot is similar in size to a normal Debian pbuilder chroot,
mainly because it is a full build environment, not an installation environment.
This directory contains my experiments with debootstrap, using this pbuilder
model, trying to make a complete Emdebian cross-building environment that can
be compressed to a base.tgz. Changes to the chroot can be discarded, just as
with pbuilder, allowing dependencies to be tested. The main benefit is that
packages can be built without having to install long chains of cross
dependencies via apt-cross or dpkg-cross on the main system. To me, it's the
only way to cross-build GUI suites like GPE against a background of changing
dependencies.
In the pbuilder model, Emdebian builds a chroot for the build architecture
(amd64/i386 etc.) - except that it will run emdebian-tools instead of pbuilder
to create the arm binaries (or whichever architecture is the dpkg-cross
default). I expect the same code to work for arm chroots on amd64 etc, but
mechanisms already exist for those so it's not the priority.
In order to make best use of the existing pbuilder code, these are shell scripts
whereas the rest of emdebian-tools uses perl.
DEPENDENCIES
------------
To emdebianise and cross-build packages, the chroot needs to install
emdebian-tools. This brings in the majority of dependencies to support building
Debian and Emdebian packages. This (current sample) code uses part of the
pbuilder source so that the eventual chroots behave as similarly as possible to
pbuilder and pdebuild in Debian. Therefore, the emdebian pbuilder chroot is NOT
designed or intended to be installed on any embedded device - it is intended for
cross-building packages for Emdebian only. See the SLIND installer for more
information or the emsandbox script in emdebian-tools.
empdebuild depends on pbuilder and installing emdebian-tools within a chroot
causes pbuilder to be installed inside the chroot. Whilst empdebuild and emsandbox
could be split out into a separate package to prevent pbuilder being needed inside
the chroot, there are corner cases where this can be useful providing sufficient
care is taken.
DIFFERENCES TO PBUILDER
-----------------------
1. emdebian-tools handles the 'installaptlines' subroutine.
2. emdebian-tools dependencies handle the installation of build-essential dpkg-dev
and apt that pbuilder normally does separately.
3. emdebian-tools handles the BUILDPLACE via debconf.
4. Other embootstrap options are hardcoded - BUILDRESULT is placed in BUILDPLACE,
APTCACHE also and APTCACHEHARDLINK is set to yes.
5. emdebian-tools provides the emdebianised source package and patches.
EMDEBIAN NATIVE CHROOT MODEL
============================
The same code should also be able to create a native chroot so that the
cross-built packages can be installed alongside each other for more testing.
These chroots have already been tested and instructions exist in the Wiki:
http://wiki.debian.org/EmDebian/CrossDebootstrap
Trying to cross-build inside scratchbox limits you to where scratchbox will
install which is only certain architectures. emdebian-tools is about
cross-building Debian packages using normal Debian tools on a normal Debian
system. Emdebian and emdebian-tools are designed to make building inside
scratchbox redundant because it simply isn't sufficiently flexible. A
scratchbox2 has been mooted but nothing has happened yet.
Cross-build using normal tools (maybe using the chroot as above) and then test
either on a native device or via scratchbox if you really have to.
An Emdebian native chroot would be an arm chroot running on an amd64 system -
indeed it would need to support creation of a chroot *for* any supported Debian
architecture and be able to create and run that chroot *on* any supported
Debian architecture.
This is only the first draft - if there are areas that need further clarification
or updating, please email the debian-embedded mailing list.

TODO for bootstrap / pbuilder config.
(no particular order)
note: pbuilder bug - default mirror does not include deb-src version.
also: gnupg needs the user directory and to be run once for
dpkg-source! :-(
also need apt-get build-dep if using emchain
copy build log and built files out of jail/ before compressing
define parameters - inherit from pbuilderrc
These chroots have already been tested and instructions
exist in the Wiki. http://wiki.debian.org/EmDebian/CrossDebootstrap
dpkg filter to remove unneeded files:
1. /var/lib/dpkg/info/*.symbols
2. /var/lib/dpkg/available-old
3. /var/lib/dpkg/status-old
modify dpkg to drop /var/log/dpkg.log
or simply mount /var/log, /var/cache in RAM.
modify apt to remove unwanted files:
/var/cache/apt/(src)?pkgcache.bin
always run apt-get clean
always drop files in /var/lib/apt/lists/
Split out /usr/share/X11/locale/ (1.3Mb)
Drop /usr/lib/xorg/modules/libscanpci.so (2Mb)
X fails to start without:
/usr/lib/xorg/modules/libpcidata.so

Root filesystem tarballs created with emsandbox need minimal
configuration on the embedded device before the first boot.
.
Supports customisation of package selection and of files created
within the root filesystem.

Description: multiple repository bootstrap based on apt
debootstrap replacement with multiple repository support
using apt to handle all dependency issues and conflicts.
.
Includes support for foreign architecture multistraps that need
only minimal configuration on the final device. Supports cleaning
up the generated bootstrap filesystem to remove downloaded packages
and hooks to modify the files in the bootstrap filesystem after
the packages have been unpacked but before being configured.
.
Unlike debootstrap, multistrap relies on working versions of
dpkg and apt outside the final filesystem.

<title>DESCRIPTION</title>
<para>Note that <command>empdebuild</command> does not support all the
options available to <command>pbuilder</command>.
</para>
<para><command>empdebuild</command> is an Emdebian version of pdebuild, building
Emdebian packages in a chroot using code from pbuilder. The Emdebian chroot includes the
cross-building toolchain from Emdebian for the requested architecture and includes
support for installing cross versions of package dependencies via
<command>apt-cross</command> with all the advantages of a chroot - identification of
missing dependencies and the ability to build packages without installing the dependencies
on the main system, e.g. to support a buildd.
</para>
<note>
<title>empdebuild is a build chroot</title>
<para><command>empdebuild</command> creates a chroot for the same architecture as
the system running <command>empdebuild</command> and then installs a cross-building
toolchain from Emdebian using the <command>dpkg-cross</command> default
architecture or the specified architecture. This has some important results:
</para>
<orderedlist>
<listitem>
<para>The chroot is a Debian system running <filename>emdebian-tools</filename>
and is equivalent to a typical installation of emdebian-tools
<emphasis>after</emphasis> <command>emsetup</command> has been completed
successfully. This includes installing perl and debconf inside the chroot.
</para>
</listitem>
<listitem>
<para>A suitable Emdebian toolchain will be installed in the chroot.
</para>
</listitem>
<listitem>
<para>The same cache files are needed inside the chroot as would be needed on the
main system - cross-built binaries <emphasis role="bold">cannot</emphasis> be run
within the the chroot. All the normal emdebian patch files will be needed.
</para>
</listitem>
<listitem>
<para>This is a full build system with native and cross compilers, development
packages, autotools and subversion. It is <emphasis role="bold">NOT</emphasis>
suitable for installation on any device. Use <command>emsandbox</command>
instead.
</para>
</listitem>
<listitem>
<para>The chroot disables the installation of recommended packages by
apt using the Install-Recommends "false" option.
</para>
</listitem>
</orderedlist>
</note>
<para>Use <command>emsandbox</command> to create cross chroots (where the
chroot is built for a different architecture to the system running the chroot),
e.g. to prepare a rootfs for installation on an arm device using emdebian-tools
installed on i386, amd64 etc. See <command>emsandbox</command> (1).
</para>

<refsect1 id="commands">
<title>COMMANDS</title>
<para>Options for <command>dpkg-buildpackage</command> can be given

<para>When setting up any chroot, debconf is set to use the default values

<para>Updates the Emdebian environment, including emdebian-tools and

or toolchain packages that fail to install, allow the update to continue as
normal, then login to the chroot with the <option>--save-after-login</option>
option. If the problem relates to a package named <filename>$PACKAGE-$ARCH-cross</filename>
not <filename>$PACKAGE-$ARCHTYPE</filename> ($ARCHTYPE for arm = arm-linux-gnu), this
package is handled by <command>dpkg-cross</command> and <command>apt-cross</command>.
Use <command>apt-cross -a $ARCH -v -i $PACKAGE</command> (omit the -$ARCH-cross suffix)
to update such packages ahead of the Emdebian repository. Use
<command>apt-get dist-upgrade</command> and <command>emsetup -a $ARCH --yes</command>

the updated packages will be saved alongside the updated chroot.

<title>unpack_debootstrap</title>
<para>Specialized routine that replaces the normal second stage of
debootstrap (you may consider it a series of hacks if you prefer).
unpack uses dpkg to extract the files from the .deb package and
process the control information. Unlike <command>dpkg</command>
<option>--unpack</option>, the unpack routine does
<emphasis role="bold">NOT</emphasis> run any maintainer scripts which
would inevitably fail in a cross built environment.
Instead, it updates the relevant dpkg status and database files
in the root filesystem and leaves the package in the unpacked state.
</para>
<para>unpack_debootstrap also sets up the busybox applets - future
versions may split this functionality into a separate function.
</para>
<para>unpack_debootstrap also performs checks on /usr/sbin/invoke-rc.d
and /usr/sbin/update-rc.d - future versions may split this functionality
into a separate function.
</para>
<para>Finally, unpack_debootstrap removes all .deb package files
from /var/cache/apt/archives. The remaining task (dpkg --configure -a)
is performed via emsecondstage.</para>

<title>DESCRIPTION</title>
<para><command>emsandbox</command> supports customised generation of
basic root filesystems from cross-built Emdebian packages, ready for
unpacking and configuring on an embedded device.
</para>
<para>Note that <filename>emsandbox</filename> does not support all the
options available to <filename>debootstrap</filename>. Some of the
debootstrap options that are supported are implemented as machine
specific configuration files in your Emdebian work directory.
(See <option>--machine</option> and <option>--variant</option>.)
</para>
<para><filename>emsandbox</filename> is a wrapper for debootstrap to prepare
an Emdebian root filesystem, using Emdebian packages and a native chroot
via 'debootstrap --foreign' and code from pbuilder.
</para>
<para>The Emdebian rootfs, as generated by <command>emsandbox</command>
is not fully configured - packages are unpacked and certain support
files are created but none of the packages are configured (not even
the pre-install scripts). This last stage is the only process that
<emphasis>must</emphasis> be run on the actual device
<emphasis>before the first boot</emphasis>, using the <command>emsecondstage</command>
script which requires a working <command>chroot</command> environment.
Typically, <command>emsecondstage</command> is run from some kind of
minimal bootloader environment that has sufficient support for mounting
subsystems like proc and filesystems like the root filesystem partition
and can chroot into the root filesystem. This method means that the
majority of the work of creating the root filesystem can be done on
the build machine.
</para>
<para>The tarball created by <command>emsandbox</command> should be
copied onto the target device and unpacked using:
</para>
<programlisting>
# cd /mnt/target/dir
# tar -xzpf emdebian-arm.tgz
</programlisting>
<para>Immediately after unpacking, start the package configuration
by running <command>./emsecondstage</command> on the target device.
(Configuration involves running the cross-built binaries and is the
only part of the process that must be run on the target device.)
</para>
<para><command>emsecondstage</command> should <emphasis>always</emphasis>
be run from the directory into which it was installed.

# This shell library requires perl and pbuilder (which means bash!) !
# Draws in POSIX shell functions from emrootfslib to be able to call
# in functions from first_stage_install within debootstrap. The only
# reasons to continue putting new functions in here are if:
# 1. the functions are only useful to create cross-building chroots OR
# 2. the functions need to call pbuilder code directly.
# There should be no need to call pbuilder code within scripts that
# generate a root filesystem.
# Intended solely for use on the build machine. Do not use these functions
# in second_stage_install !

empdebuild - cross-building chroot Emdebian package builder
version $OURVERSION
Syntax: sudo empdebuild [OPTIONS] [COMMAND]
Only one command can be actioned at any one time.
Options must precede the command to take effect.
Commands:
-?|-h|--help|-version: print this help message and exit
--create|create: create a cross-building base .tgz for unstable
--update|update: update the base .tgz and save changes
--build|build: build the current package in the chroot
(needs to be run in the top source directory)
--autobuild|autobuild PACKAGE: build the specified package in the chroot
(used by the autobuilder)
--login|login: Login to the chroot to run tests or fix problems.
--clean|clean: Clean up all build sub directories.
Options:
--arch: Override the default cross-build architecture (from dpkg-cross).
--testing: Override the default suite (unstable) to use testing
instead. This is a fallback option for use during
toolchain transitions in unstable.
--save-after-login: Allow changes made within the chroot login to persist.
--login-after-fail: In case of error, try to log in to the new chroot.
-- OPTIONS dpkg-buildpackage options
(except: -uc -us [default] -a [ignored])
Although based on pbuilder, empdebuild cannot support the full range of
pbuilder commands or options. In addition, creating a cross-building chroot for
testing involves a variety of changes to the creation of a similar chroot for
unstable so testing is only supported as an override, rather than using the
pbuilder method of a --distribution option.
When testing local changes made with emdebuild, use 'empdebuild --build' which
will use the .diff.gz from the current working directory.
Once the local changes are complete and are committed to Emdebian SVN, you
can use 'empdebuild --autobuild PACKAGE' to ensure that the patches are
usable for the autobuilder.
Options to dpkg-buildpackage can be specified after the -- option.
Note that '-uc' and '-us' are set by default and '-a' will be ignored
(because arch is controlled separately). Options are passed down to
emdebuild unchanged.

$PROG - cross-built chroot Emdebian rootfs builder
version $OURVERSION
Syntax: sudo $PROG [OPTIONS] [COMMAND]
Commands:
-?|-h|--help|--version: print this help message and exit
--create|create: create a cross-built base tarball for ARCH
Options:
-a|--arch: Override the default cross-build architecture (from dpkg-cross).
-s|--script FILENAME: Override the default package set and second-stage install.
-S|--suite NAME: Override the default suite [unstable]
-m|--machine NAME: Specify a machine name for customisation hooks
-v|--variant NAME: Specify a machine variant name for customisation hooks
--machine-path PATH: Specify a path to replace the $WORK/machine default
Although based on debootstrap, $PROG cannot support the full range of
debootstrap commands or options.
Some customised $PROG scripts are provided with emdebian-tools. The
default uses the standard Emdebian 'busybox' package with 'dpkg' and 'apt'.
Replacement scripts need to be full debootstrap suite shell scripts that specify
how to complete the first and second stage installations. If the script uses
'busybox', the second-stage install function must be compatible with the
shell applet in busybox - avoid bashisms!
Overriding the default suite also configures the root filesystem to look
for updates within the specified suite.

$PROG - emdebian roots installer
Syntax: sudo $PROG
sudo $PROG [COMMAND]
Commands:
-?|-h|--help|-version: print this help message and exit
Although based on debootstrap, $PROG cannot support the full range of
debootstrap commands or options.
The standard Emdebian rootfs uses the 'busybox' package with 'dpkg' and
'apt'. Replacement scripts need to be full debootstrap suite shell
scripts that specify how to complete the first and second stage
installations. If the script uses 'busybox', the second-stage install
function must be compatible with the shell applet in busybox - avoid
bashisms!
Machine specific customisation hooks need to be shell scripts
(not bash) located in /debootstrap/machine/config.sh in the top level
directory of the rootfs. If you used 'emsandbox --machine ...' to
create the rootfs, the config.sh script for your machine and variant
has already been installed and will be executed by $PROG.
If the root filesystem used the 'unpack' method, $PROG only has to
apply the machine specific customisation hooks.

# This config script provides a method of adjusting the tarball
# contents immediately after the second stage install has completed.
# The script is copied into the tarball and unpacked to:
# $TARGET/machine/config.sh
# NOTE: At this stage, the ./debootstrap/ directory has already been
# removed. Do not rely on the tarball itself being available either.
# If any other files or scripts are needed by your additions to this
# script, you must ensure that setup.sh includes them into the tarball.
# It may be easier to create a normal Debian package that can do the
# job for you.
# This example file can act as a skeleton for your own scripts.
# Copy into $WORK/machine/$MACHINE/$VARIANT/ and edit.
# ($WORK is your emdebian working directory, as set in debconf.)

# This is a standard shell conf file, included directly into embootstrap
# This example file can act as a skeleton for your own scripts.
# Copy into $WORK/machine/$MACHINE/$VARIANT/ and edit.
# ($WORK is your emdebian working directory, as set in debconf.)
# Use 'default' as the variant directory if no other variants exist.
# packages.conf is intended to be the principal place for adjusting
# the emsandbox tarball to suit the needs of specific machine variants.
# setup.sh and config.sh can fine tune the results but in order to avoid
# reinventing the wheel, if more than a few machines need similar
# adjustments to the same files, future versions of packages.conf will
# collate those into a single configuration parameter available to all.
# More options and parameters will be added in due course, including
# support for additional sources for /etc/apt/sources.list and single
# parameter changes to certain files like /etc/inittab.
# Due to limitations in the current debootstrap support, the only way
# of adding packages to the first stage is by providing a
# customised suite script. Even if emsandbox migrates to using a tool
# from Stag to overcome shortcomings in debootstrap, support for
# packages.conf, setup.sh and config.sh will remain.
# INCLUDE adds a comma separated list of package names to the list
# of packages added to the tarball and installed in the second stage.
# Currently, debootstrap has problems with multiple repositories so
# either upload this package to the same repository as your other
# packages or create an apt-proxy that can serve as a local repository,
# set it in PROXY and specify a usable mirror for the device in MIRROR.
# DEFAULT: empty
INCLUDE=
# SCRIPT overrides the default emsandbox suite-script that debootstrap
# uses to determine the base and required packages and the all important
# sequence in which the packages can be installed. SCRIPT can be overridden
# on the emsandbox command line.
# DEFAULT: /usr/share/emdebian-tools/emdebian.crossd
SCRIPT=
# MIRROR overrides the default emsandbox mirror. This repository will
# will be set in /etc/apt/sources.list and will also be used by
# debootstrap to obtain all packages for the tarball unless
# PROXY is also set.
# DEFAULT: http://www.emdebian.org/emdebian/
MIRROR=
# PROXY specifies a separate repository to pass to debootstrap that may
# be local or otherwise not intended for use once the tarball is installed
# Use MIRROR to set the same value in debootstrap and /etc/apt/sources.list
# If PROXY is specified without MIRROR, the default emsandbox MIRROR will
# be written into /etc/apt/sources.list
# DEFAULT: empty
PROXY=
# It is often useful to include a kernel image and/or modules or extra
# files but these may be in generated or variable paths - e.g. including
# a version string or in another part of the filesystem. To include these
# files in the emsandbox tarball, write out a list of paths into a file in
# $WORK/machine/$MACHINE/$VARIANT and read the contents into the
# setup.sh script. The files copied or unpacked into the $BUILDPLACE
# will then be included into the tarball.
# If there are extra files with absolute paths that do not change
# between releases, specify them in EXTRA. Absolute paths only -
# wildcards supported by 'cp' are allowed. Files are copied into
# $BUILDPLACE unchanged to be processed by setup.sh (if it exists).
EXTRA=
# TARBALL_NAME overrides the default name (emdebian-$ARCH) of the tarball
# Do not specify a path here, just a filename with the .tgz suffix
# DEFAULT: emdebian-$ARCH.tgz where $ARCH is specified to emsandbox or
# as the dpkg-cross default architecture.
