grml-live provides the build system for creating a grml and Debian based Linux
Live-CD. The build system is based on
-link:http://www.informatik.uni-koeln.de/fai/[FAI] (Fully Automatic
+link:http://fai-project.org/[FAI] (Fully Automatic
Installation). grml-live uses the "fai dirinstall" feature to generate a chroot
system based on the class concept of FAI (see later sections for further
details) and provides the framework to be able to generate a full-featured ISO.
Specify the CLASSES to be used for building the ISO via FAI. By default only
the classes GRMLBASE, GRML_MEDIUM and I386 are assumed, resulting in a small base
system (being about ~180MB total ISO size). If using a non-I386 system (like
-amd64) you should specify the appropriate architecture as well. Additionally you
+AMD64) you should specify the appropriate architecture as well. Additionally you
can specify a class providing a grml-kernel (see
<<classes,the 'CLASSES' section in this document>> for details about available classes).
So instead of GRML_MEDIUM you can also use GRML_SMALL and GRML_FULL.
+[IMPORTANT]
+All class names should be written in uppercase letters. Do not use a dash, use
+an underscore. So do not use "amd64" but "AMD64", do not use "FOO BAR" but
+"FOO_BAR".

[[usage-examples]]
Usage examples
If you want to use your own configuration, extend an existing configuration
and/or add additional packages to your ISO just invent a new class (or extend an
existing one). For example if you want to use your own class named "FOOBAR" just
-set CLASSES="GRMLBASE,GRML_SMALL,I386" inside /etc/grml/grml-live.local or
-invoke grml-live using the classes option: "grml-live -c
+set CLASSES="GRMLBASE,GRML_SMALL,I386,FOOBAR" inside /etc/grml/grml-live.local
+or invoke grml-live using the classes option: "grml-live -c
GRMLBASE,GRML_SMALL,I386,FOOBAR ...".
More details regarding the class concept can be found in the documentation of
this class as well, so unless you have a really good reason you should always
use this class.
-* GRML_FORENSIC: tools for forensic investigations which has been created
-by people from link:http://www.forensic-geeks.org/[forensic-geeks.org].
-
* GRML_FULL: full featured grml, also known as the "normal", full grml.
* GRML_MEDIUM: medium sized grml version, known as grml-medium

Requirements for the build system

Current state of grml-live with squashfs-tools and kernel
---------------------------------------------------------
-To make it easier to track problems this section documents current state of
-grml-live playing together with squashfs-tools / squashfs-lzma-tools (for
-building the compressed file) and the kernel version. Documentation of this
-section is up2date by 7rd of september 2009, please report any bugs you
-encounter.
+Use squashfs-tools >=4.2-1 (available from Grml repositories as well as from

+Difference between squashfs-lzma-tools, squashfs-lzma-tools4 and squashfs-tools
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Whereas the ZLIB compression is much faster in the build process, the LZMA
compression provides a smaller resulting ISO. If you're wondering: the official
Squashfs-tools was introduced in Debian and once provided support for LZMA
compression. Sadly LZMA compression within squashfs-tools became unsupported and
-therefore squashfs-lzma-tools had to be introduced by the Grml team. Different
-kernel versions provide different squashfs file formats (version 3.x for kernel
-versions until 2.6.28-grml[64], since kernel 2.6.31-grml[64] it's the 4.x
-format).
+therefore squashfs-lzma-tools[4] had to be introduced and maintained by the Grml
+team. Different kernel versions provide different squashfs file formats. Kernel
+versions until 2.6.28-grml[64] used the 3.x file format but those outdated
+kernels aren't supported by grml-live automatically anymore nowdays (manual
+handling through SQUASHFS_BINARY possible though). Kernel versions
+2.6.31-grml[64] and 2.6.33-grml[64] use openwrt's squashfs lzma file format
+version 4. Kernel versions starting with 2.6.35-grml[64] use the mainline ondisk
+file format version 4.
If you're wondering which package supports what, here's a short overview:
-* squashfs-tools 1:4.0-1: ZLIB as default, no LZMA support/options, file format
-version 4
+* squashfs-lzma-tools4 4.0-x: ZLIB as default, LZMA support via '-comp lzma'

+grml-live builds featuring kernels >=2.6.35-grml[64]

+2.6.35-grml[64]. It supports LZMA as well as ZLIB compression. Just use the
+defaults for enabling LZMA or use grml-live's '-z' option if you want to use
+ZLIB compression instead.

+
+Execute the following commands (requires root):
+
+ ARCH='amd64' # replace with i386 if necessary
+ SUITE='squeeze' # using the current stable release should always work
+ debootstrap --arch "$ARCH" --exclude=info,tasksel,tasksel-data "$SUITE" "$ARCH" http://debian.netcologne.de/debian
+ cd "$ARCH"
+ rm var/cache/apt/archives/*.deb
+ tar zcf ../"${ARCH}".tar.gz *
+
+And finally place the generated tarball in /etc/grml/fai/config/basefiles/ (note
+that it needs to be uppercase letters matching the class names, so: AMD64.tar.gz
+for amd64 and I386.tar.gz for i386).

+How do I set up an autobuild environment?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to set up a system like link:http://daily.grml.org/[daily.grml.org]
+the Debian package grml-live-buildd provides all you need to start. Start with
+figuring out the cron job script /usr/share/grml-live/buildd/cronjob.sh.
+
+If you want to automatically update the grml-live Debian package on your build
+system based on the git tree of grml-live (so you get bleeding edge of
+development which might is interesting for services like daily.grml.org) the
+provided release_helper.sh script provides everything you need. Execute as root:
+
+ echo "deb file:/home/grml-live-git/grml-live.build-area/ ./" >> /etc/apt/sources.list.d/grml-live.list
+ adduser --disabled-login --disabled-password grml-live-git
+
+Execute 'visudo' to update sudo configuration and add the following line:
+
+ grml-live-git ALL=NOPASSWD: /usr/bin/apt-get
+
+Switch to user grml-live-git and configure the rest:
+
+ su - grml-live-git
+ mkdir grml-live.build-area
+ git clone git://git.grml.org/grml-live.git
+ git config --global user.name "Grml-Live Git Autobuild"
+ git config --global user.email "grml-live-git@$(hostname)"
+
+Finally install a cron job (as user grml-live-git) like:
+
+ 30 00 * * * cd /home/grml-live-git/grml-live.git/ && env AUTOBUILD=1 scripts/release_helper.sh >/home/grml-live-git/grml-live-build.log
+
+Tip: To find out the build date of the installed grml-live package just execute:
+
+ % apt-cache policy grml-live | grep 'Installed.*autobuild'
+ Installed: 0.13.1~autobuild1300450381
+
+and run "date -ud @$STRING" where $STRING is the number behind the "autobuild",
+like:
+
+ % date -ud @1300450081
+ Fri Mar 18 12:08:01 UTC 2011
