Description
-----------
-a **ARCHITECTURE**::
Use the specified architecture instead of the currently running one. This
-allows building a 32bit system on a 64bit host. Please notice that real
+allows building a 32bit system on a 64bit host (though you can't build a 64bit
+system on a 32bit system/kernel of course). Please notice that real
crosscompiling (like building a ppc system on x86) isn't possible due to the
-nature and the need of working in a chroot.
+nature and the need of working in a chroot. Currently supported values: i386
+and amd64.
+
+ -b::
+
+Build the ISO without updating the chroot via FAI. This option is useful for
+example when working on stable releases: if you have a working base
+system/chroot and do not want to execute any further updates (via "-u" option)
+but intend to only build the ISO.
+
+ -B::
+
+Build the ISO without touching the chroot at all. This option is useful if
+you modified anything that FAI or grml-live might adjust via grml's FAI
+scripts. It's like the '-b' option but even more advanced. Use only if you
+really know that you do not want to update the chroot.
-c **CLASSES**::
Specify the CLASSES to be used for building the ISO via FAI. By default only
-the classes GRMLBASE, GRML_SMALL and I386 are assumed, resulting in a small base
-system (being about ~150MB total ISO size). If using a non-I386 system (like
+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
can specify a class providing a grml-kernel (see
-/etc/grml/fai/config/package_config/ for a full list). So instead of GRML_SMALL
-you can also use GRML_MEDIUM and GRML_FULL instead.
+<<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.
-C **CONFIGURATION_FILE**::
The specified file is used as configuration file for grml-live. By default
-/etc/grml/grml-live.conf is used for main configuration. If a file named
+/etc/grml/grml-live.conf is used as default configuration. If a file named
/etc/grml/grml-live.local exists it is used as well (sourced after reading
-/etc/grml/grml-live.conf to allow overriding settings). As a last option the
-specified configuration file is sourced so it is possible to override settings
-of /etc/grml/grml-live.conf as well as of /etc/grml/grml-live.local. Please
-notice that all configuration files have to be adjusted during execution of
-grml-live, so please make sure you use /etc/grml/grml-live.conf as a base for
-your own configuration file. Please also notice that the configuration file
-specified via this option is **not** (yet) supported inside the
-scripts/hooks/classes at /etc/grml/fai/config. Instead use
-/etc/grml/grml-live.conf and/or /etc/grml/grml-live.local for configuration
-stuff used inside /etc/grml/fai/config.
+/etc/grml/grml-live.conf meant as main file for local configuration). As a last
+option the specified configuration file is sourced so it is possible to override
+settings of /etc/grml/grml-live.conf as well as of /etc/grml/grml-live.local.
+Please notice that all configuration files have to be adjusted during execution
+of grml-live, so please make sure you use /etc/grml/grml-live.conf as a base for
+your own configuration file (usually /etc/grml/grml-live.local). Please also
+notice that the configuration file specified via this option is **not** (yet)
+supported inside the scripts/hooks/classes at /etc/grml/fai/config. Instead use
+/etc/grml/grml-live.local for configuration stuff used inside
+/etc/grml/fai/config.
+
+ -d **DATE**::
+
+Use specified date as build date information on the ISO instead of the default.
+The default is the date when grml-live is being executed (retrieved via
+executing 'date +%Y-%m-%d'). The information is stored inside the file
+/GRML/grml-version on the ISO, /etc/grml_version in the squashfs file and in all
+the bootsplash related files. This option is useful if you want to provide an
+ISO with release information for a specific date but have to build it in
+advance. Usage example: '-d 2009-10-30'
-F::
-g **GRML_NAME**::
Set the grml flavour name. Common usage examples: grml, grml-small, grml64.
+Please do NOT use blanks and any special characters like '/', ';' inside
+GRML_NAME, otherwise you might notice problems while booting.
-h::
Specify name of ISO which will be available inside $OUTPUT_DIRECTORY/grml_isos
by default.
+ -I **CHROOT_INSTALL**::
+
+Specify name of source directory which provides files that should become part of
+the chroot/ISO. Not enabled by default. Note: the files are installed under '/'
+in the chroot so you have to create the rootfs structure on your own.
+
+ -n::
+
+Skip creation of the ISO file. This option is useful if you want to build/update
+the chroot and/or recreate the squashfs file without building an ISO file.
+
-o **OUTPUT_DIRECTORY**::
Main output directory of the build process of FAI. Some directories are created
ISO are located, including the compressed squashfs file), grml_chroot (the
chroot system) and grml_isos (where the resulting ISO is stored).
+ -q::
+
+Build the ISO without (re-)creating the squashfs compressed file using mksquashfs.
+This option is useful if you just want to update parts outside the chroot in the ISO.
+Consider combining this option with the build-only option '-b'.
+
-r **RELEASENAME**::
Specify name of the release.
-s **SUITE**::
Specify the Debian suite you want to use for your live-system. Defaults to
-"etch" (being current Debian/stable). Supported values are: etch, lenny, sid.
+"lenny" (being current Debian/stable). Supported values are: etch, lenny, sid.
+Debian "squeeze" (current Debian/testing) requires base.tgz
+(/etc/grml/fai/config/basefiles/....tar.gz) or a recent version of debootstrap.
-t **TEMPLATE_DIRECTORY**::
Use ZLIB instead of LZMA compression in mksquashfs part of the build process.
+[[usage-examples]]
Usage examples
--------------
To get a small Debian-unstable and grml-small based Live-CD using
/home/mika/grml-live as build and output directory just use:
- # grml-live -c GRMLBASE,GRML_SMALL,I386 -o /home/mika/grml-live
+ # grml-live -s sid -c GRMLBASE,GRML_SMALL,I386 -o /home/mika/grml-live
+
+To get a medium sized, Debian-unstable and grml-based Live-CD for i386
+architecture using /grml/grml-live as build and output directory just run:
+
+ # grml-live -s sid -a i386 -c GRMLBASE,GRML_MEDIUM,I386
To get a small, Debian-unstable and grml-based Live-CD using /tmp as build and
output directory and use grml_0.0-3.iso as ISO name (placed inside
you should have >=1GB of RAM) just run "mount -o remount,suid,dev,rw /dev/shm"
and use /dev/shm as build and output directory - resulting in very fast build
process. But please be aware of the fact that rebooting your system will result
-in an empty /dev/shm, so please another directory for $CHROOT_OUTPUT,

Main features of grml-live
--------------------------
* multi-arch support (work in progress)
+[[class-concept]]
The class concept
-----------------
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
-extend CLASSES="GRMLBASE,GRML_SMALL,I386" inside /etc/grml/grml-live.conf to
-CLASSES="GRMLBASE,GRML_SMALL,I386,FOOBAR" or invoke grml-live using the classes
-option: "grml-live -c GRMLBASE,GRML_SMALL,I386,FOOBAR ...".
+set CLASSES="GRMLBASE,GRML_SMALL,I386" 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
FAI itself (being available at /usr/share/doc/fai-doc/).
+[[X7]]
+[[classes]]
Available classes
-----------------
-Documentation to be done...
+The package selection part of the classes can be found in
+/etc/grml/fai/config/package_config whereas some further classes are defined for
+example in /etc/grml/fai/config/scripts/ so specific feature sets can be
+selected. The following classes are predefined:
+
+* DEBORPHAN: get rid of all packages listed in output of Deborphan
+
+* GRMLBASE: the main class responsible for getting a minimal subset of what's
+defining a grml system. Important parts of the buildprocess are specified in
+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
+
+* GRML_POWERPC: grml for PowerPC architecture, not supported yet (still work in
+progress)
+
+* GRML_SMALL: minimum sized grml version, known as grml-small
+
+* LATEX: LaTeX(-related) packages like auctex, texlive,...
+(which used to be shipped by grml before the LaTeX removal)
+
+* LATEX_CLEANUP: get rid of several very large LaTeX directories
+(like some /usr/share/doc/texlive-*, /usr/share/doc/texmf,...)
+
+* LOCALES: use full featured locales setup (see /etc/locale.gen.grml). This
+avoids to get rid of /usr/share/locale - which happens by default otherwise - as
+well.
+
+* NO_ONLINE: do not run scripts during the chroot build process which require a
+network connection
+
+* RELEASE: run some specific scripts and commands to provide the workflow for an
+official grml release
+
+* REMOVE_DOCS: get rid of documentation directories (like /usr/share/doc,
+/usr/share/man/, /usr/share/info,...)
+* XORG: providing important packages for use with a base grml-featured X.org
+setup

+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.
+
+Difference between squashfs-lzma-tools 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
+Grml builds use the LZMA compression.
+
+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).
+
+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-tools 1:3.3-7: ZLIB as default, no LZMA support/options, file format
+version 3
+
+* squashfs-tools 1:3.2r2-9exp1: LZMA as default, ZLIB support via -nolzma
+option, file format version 3
+
+* squashfs-lzma-tools 4.0-2: ZLIB as default, LZMA support via -lzma option,
+file format version 4
+
+* squashfs-lzma-tools 3.3-1: LZMA as default, ZLIB support via -nolzma option,
+file format version 3
+
+Depending on the kernel version you want to use you need different versions
+squashfs-tools/squashfs-lzma-tools. Yes, that's pretty a mess (don't ask how
+much this sucks for us developers) - though this is supposed to calm down with
+the recent integration of squashfs file format 4 in the mainline kernel. Support
+for LZMA is pending and should dramatically simplify the situation for
+developers as well as users as soon as it's available mainline.
+
+Using squashfs-lzma-tools 4.0-2 on the build system
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+squashfs-lzma-tools 4.0-2 is available via the grml repositories. It provides
+the mksquashfs-lzma and unsquashfs-lzma binaries. The package does NOT conflict
+with Debian's squashfs-tools package (you can install both of them at the same
+time).
+
+The packages can be downloaded from
+link:http://deb.grml.org/pool/main/s/squashfs-lzma-tools/[http://deb.grml.org/pool/main/s/squashfs-lzma-tools/]
+
+It provides support for the new squashfs file format version 4 and therefore
+requires kernel versions newer than 2.6.28-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 instead.
+
+* Kernel 2.6.23-grml[64]: does not work
+* Kernel 2.6.26-grml[64]: does not work
+* Kernel 2.6.28-grml[64]: does not work
+* Kernel 2.6.31-grml[64]: works
+
+[NOTE]
+
+Please use squashfs-lzma-tools >=4.0-2 from Grml if you want to remaster any
+grml release being MORE RECENT than 2009.05.
+
+Using squashfs-tools 1:4.0-1 on the build system
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+squashfs-tools 1:4.0-1 is available in Debian/unstable and Debian/testing. It
+provides the mksquashfs and unsquashfs binaries. The package does NOT
+conflict with the squashfs-lzma-tools 4.0-2 package (you can install both of
+them at the same time).
+The packages can be downloaded from
+link:ftp://ftp.de.debian.org/debian/pool/main/s/squashfs/[ftp://ftp.de.debian.org/debian/pool/main/s/squashfs/]
+
+It provides support for the new squashfs file format version 4 and therefore
+requires kernel versions newer than 2.6.28-grml[64].
+
+It does NOT support LZMA compression. If you need LZMA support please use
+Grml's squashfs-lzma-tools (see section above) instead.
+
+* Kernel 2.6.23-grml[64]: does not work
+* Kernel 2.6.26-grml[64]: does not work
+* Kernel 2.6.28-grml[64]: does not work
+* Kernel 2.6.31-grml[64]: works
+
+[NOTE]
+Please use squashfs-tools 1:4.0-1 only if you want to remaster grml releases
+MORE RECENT than 2009.05 using the ZLIB compression.
+
+Using squashfs-lzma-tools 3.3-1 on the build system
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+squashfs-lzma-tools 3.3-1 from the grml repository supports kernel
+2.6.26-grml[64] and 2.6.28-grml[64] using both LZMA and ZLIB (-nolzma)
+compression. It's the recommended package for building ISOs with grml-live
+currently!
+
+The packages can be downloaded from
+link:http://deb.grml.org/pool/main/s/squashfs-lzma/[http://deb.grml.org/pool/main/s/squashfs-lzma/].
+
+[NOTE]
+Please use squashfs-lzma-tools 3.3-1 if you want to remaster grml release
+2008.11 or 2009.05.
+
+Using squashfs-tools 1:3.3-7 on the build system
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+squashfs-tools 1:3.3-7 is available through
+http://grml.org/squashfs/squashfs-tools_3.3-7_i386.deb (for x86) or
+http://grml.org/squashfs/squashfs-tools_3.3-7_amd64.deb (for amd64) [both build
+on and for Debian/etch but working with testing and unstable as well].
+
+Please notice that squashfs-tools 1:3.3-7 does NOT support LZMA compression at
+all (so you won't be able to remaster release 2008.11 and 2009.05 using LZMA for
+example). The -nolzma option of mksquashfs is not available therefore (even
+though grml-live will deactivate it for you automatically anyway). Please use
+squashfs-lzma-tools instead.
+
+* Kernel 2.6.23-grml: does NOT work, please use squashfs-tools 1:3.2r2-9exp1
+ instead if you still want to use kernel 2.6.23 (not
+ recommended)
+* Kernel 2.6.26-grml: works (without LZMA compression only of course!)
+* Kernel 2.6.28-grml: works (without LZMA compression only of course!)
+
+Using squashfs-tools 1:3.2r2-9exp1 on the build system
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+squashfs-tools 1:3.2r2-9exp1 is available via the grml-testing repository,
+running:
+
+ # aptitude install squashfs-tools=1:3.2r2-9exp1
+
+or directly via downloading the files
+http://grml.org/squashfs/squashfs-tools_3.2r2-9exp1_i386.deb (for x86) or
+http://grml.org/squashfs/squashfs-tools_3.2r2-9exp1_amd64.deb (for amd64).
+
+Using with ZLIB compression (SQUASHFS_OPTIONS='-nolzma' or -z
+option in grml-live cmdline):
+
+* Kernel 2.6.23-grml: works
+* Kernel 2.6.26-grml: works
+* Kernel 2.6.28-grml: supposed to work (not verified though)
+
+Using with LZMA compression:
+
+* Kernel 2.6.23-grml: works
+* Kernel 2.6.26-grml: does NOT work, please use ZLIB mode instead or switch
+ to Debian package squashfs-lzma-tools 3.3-1 (see section above).
+* Kernel 2.6.28-grml: does NOT work, please use ZLIB mode instead or switch
+ to Debian package squashfs-lzma-tools 3.3-1 (see section above).

+[[deploy-on-debian]]
+How do I deploy grml-live on a plain Debian installation?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The easiest way to get a running grml-live setup is to install grml or
+grml-medium using grml2hd (for example inside KVM, Virtualbox, VMware,... if you
+don't want to run it on a physical system). Of course using grml-live on a
+plain, original Debian installation is supported as well. So there we go.
+
+What we have: plain, original Debian Lenny (5.0).
+
+What we want: build a grml-medium ISO based on Debian/squeeze for the i386
+architecture using grml-live.
+
+[IMPORTANT]
+
+If you encounter any problems while booting the resulting ISO please be aware of
+<<current_state,the 'current state of grml-live with squashfs-tools and kernel'

+[[install-local-files]]
+How to I install further files into the chroot/ISO?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Just point the configuration variable CHROOT_INSTALL to the directory which
+provides the files you would like to install. Note that the files are installed
+under '/' in the chroot - so you have to create the rootfs structure on your
+own. Usage example:
+
+ echo "CHROOT_INSTALL=\$GRML_FAI_CONFIG/chroot_install" >> /etc/grml/grml-live.local
+ mkdir -p /etc/grml/fai/chroot_install/usr/src/
+ wget example.org/foo.tar.gz
+ mv foo.tar.gz /etc/grml/fai/chroot_install/usr/src/

non-local mirrors. Using a fallback mirror (via providing several mirrors in
GRML_LIVE_SOURCES as used by default) is a recommended setting.

+[[create-a-base-tgz]]
How do I create a base.tgz for use as NFSROOT?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
First of all build the chroot system:
mkdir /tmp/nfsroot && cd /tmp/nfsroot
- debootstrap etch /tmp/nfsroot/ http://ftp.de.debian.org/debian
+ debootstrap lenny /tmp/nfsroot/ http://cdn.debian.net/debian
tar zcf base.tgz ./
Then check out where your NFSROOT is located:
