-grml-live provides the build system for creating a grml and Debian based Linux
+grml-live provides the build system for creating a Grml and Debian based Linux
Live-CD. The build system is based on

+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.
details of a build process.
CAUTION: grml-live does **not** use /etc/fai for configuration but instead
-provides and uses /etc/grml/fai. This ensures that it does not clash with
-default FAI configuration and packages, so you can use grml-live and FAI
+provides and uses ${GRML_FAI_CONFIG} which is pointing to /etc/grml/fai by default
+(unless overridden using the ''-D'' option). This ensures that it does not clash
+with default FAI configuration and packages, so you can use grml-live and FAI
completely independent at the same time!
[NOTE]
checkout mkdebmirror (see /usr/share/doc/grml-live/examples/mkdebmirror),
debmirror(1), reprepro(1) (see /usr/share/doc/grml-live/examples/reprepro/ for a
sample configuration), apt-cacher(1) and approx(8). To avoid downloading the

-for details).
+base system again and again check out <<create-a-base-tgz,the base tar.gz
+feature>>.
Options
-------
+ -A::
+
+Clean up all output directories before running the build process. After finishing,
+clean up the Chroot target and Build target directories.
+
-a **ARCHITECTURE**::
Use the specified architecture instead of the currently running one. This
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
-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.
+the classes GRMLBASE, GRML_FULL and I386/AMD64 (depending on system
+architecture) are assumed, resulting in a base system of about 350MB
+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 <<classes,the 'CLASSES' section in this document>> for
+details about available classes). So instead of GRML_FULL 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".
+
-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 ${GRML_FAI_CONFIG}/config. Instead use
+/etc/grml/grml-live.local for configuration stuff used inside
+${GRML_FAI_CONFIG}/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'
+
+ -D **CONFIGURATION_DIRECTORY**::
+
+The specified directory is used as configuration directory for grml-live and its
+FAI. By default /etc/grml/fai is used as default configuration directory. If
+you want to have different configuration scripts, package definitions, etc. with
+without messing with the global configuration under /etc/grml/fai provided by
+grml-live this option provides you the option to use your own configuration
+directory. This directory is what's being referred to as ${GRML_FAI_CONFIG}
+throughout this documentation.
+
+ -e **EXTRACT_ISO_NAME**::
+
+The squashfs inside the specified ISO will be extracted and used as the chroot.
+This option is useful for remastering, in combination with -A and -b or -u.
-F::
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 with booting.
+GRML_NAME, otherwise you might notice problems while booting.
-h::
Specify name of ISO which will be available inside $OUTPUT_DIRECTORY/grml_isos
by default.
+ -I **CHROOT_INSTALL**::
+
+Specify name of source directory which provides files that should become part of
+the chroot/ISO. Not enabled by default. Note: the files are installed under '/'
+in the chroot so you have to create the rootfs structure on your own.
+
+ -n::
+
+Skip creation of the ISO file. This option is useful if you want to build/update
+the chroot and/or recreate the squashfs file without building an ISO file.
+
+ -N::
+
+Bootstrap the chroot without building bootloader, squashfs, or finalizing the
+ISO. Use this option if installation of some packages fails, you want to run
+custom commands or similar.
+The main use of this option is to save time by skipping stages which aren't
+necessary for bootstrapping the chroot and which would get executed more than
+once when iterating through the initial bootstrapping.
+Alternatively, use this option as a test run of grml-live. Once you are
+satisfied with the state of your grml_chroot, use grml-live **-u** to build the
+remaining stages and finalize the ISO.
+
-o **OUTPUT_DIRECTORY**::
Main output directory of the build process of FAI. Some directories are created
ISO are located, including the compressed squashfs file), grml_chroot (the
chroot system) and grml_isos (where the resulting ISO is stored).
+ -q::
+
+Build the ISO without (re-)creating the squashfs compressed file using mksquashfs.
+This option is useful if you just want to update parts outside the chroot in the ISO.
+Consider combining this option with the build-only option '-b'.
+
+ -Q::
+
+Build the ISO without generating a netboot package.
+
-r **RELEASENAME**::
Specify name of the release.
-s **SUITE**::
Specify the Debian suite you want to use for your live-system. Defaults to
-"etch" (being current Debian/stable). Supported values are: etch, lenny, sid.
+"squeeze" (being current Debian/stable). Supported values are: etch, lenny,
+squeeze, sid. Debian "squeeze" requires a recent base.tgz
+(${GRML_FAI_CONFIG}/config/basefiles/$CLASSNAME.tar.gz) or a recent version of
+debootstrap.
-t **TEMPLATE_DIRECTORY**::
Update existing chroot instead of rebuilding it from scratch. This option is
based on the softupdate feature of FAI.
+ -U **USERNAME**::
+
+Sets ownership of all build output files to specified username before exiting.
+
-v **VERSION_NUMBER**::
Specify version number of the release.
-z::
-Use ZLIB instead of LZMA compression in mksquashfs part of the build process.
+Use ZLIB instead of LZMA/XZ compression in mksquashfs part of the build process.

Usage examples
--------------
-To get a small, Debian-stable and grml-based Live-CD using /grml/grml-live
+To get a Debian-stable and Grml-based Live-CD using /grml/grml-live
as build and output directory just run:
# grml-live
-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 -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 64bit Debian-testing and grml-small based Live-CD using /srv/grml-live
+as build and output directory use the following command line on your amd64
+system:
-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
-/tmp/grml_isos) just invoke:
-
- # grml-live -o /tmp -c GRMLBASE,GRML_SMALL,I386 -s sid -i grml_0.0-3.iso
+ # grml-live -s testing -c GRMLBASE,GRML_SMALL,AMD64 -o /srv/grml-live
[NOTE]
-If you have about 700MB of free space inside /dev/shm (being a tmpfs, usually
-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 use another directory for $CHROOT_OUTPUT,
-$BUILD_OUTPUT and $ISO_OUTPUT if you plan to create more persistent output. :)
+If you have enough RAM, just run "mount -t tmpfs none /media/ramdisk" to get a
+tmpfs ("RAMDISK"), and use /media/ramdisk as build and output directory - this
+results in a very fast build process. Note that these files will be gone when
+rebooting.

Main features of grml-live
--------------------------
-* create a grml-/Debian-based Linux Live-CD with one single command
+* create a Grml-/Debian-based Linux Live-CD with one single command
* class based concept, providing a maximum of flexibility
* native support of FAI features
-* multi-arch support (work in progress)
-
+[[class-concept]]
The class concept
-----------------
GRML_SMALL, GRML_MEDIUM or GRML_FULL). The following files and directories are
relevant for class GRMLBASE by default:
- /etc/grml/fai/config/scripts/GRMLBASE/
- /etc/grml/fai/config/debconf/GRMLBASE
- /etc/grml/fai/config/class/GRMLBASE.var
- /etc/grml/fai/config/hooks/instsoft.GRMLBASE
- /etc/grml/fai/config/package_config/GRMLBASE
+ ${GRML_FAI_CONFIG}/config/scripts/GRMLBASE/
+ ${GRML_FAI_CONFIG}/config/debconf/GRMLBASE
+ ${GRML_FAI_CONFIG}/config/class/GRMLBASE.var
+ ${GRML_FAI_CONFIG}/config/hooks/instsoft.GRMLBASE
+ ${GRML_FAI_CONFIG}/config/package_config/GRMLBASE
Take a look at the next section for information about the concept of those
files/directories.
If you want to use your own configuration, extend an existing configuration
and/or add additional packages to your ISO just invent a new class (or extend an
existing one). For example if you want to use your own class named "FOOBAR" just
-extend CLASSES="GRMLBASE,GRML_SMALL,I386" inside /etc/grml/grml-live.conf to
-CLASSES="GRMLBASE,GRML_SMALL,I386,FOOBAR" or invoke grml-live using the classes
-option: "grml-live -c GRMLBASE,GRML_SMALL,I386,FOOBAR ...".
+set CLASSES="GRMLBASE,GRML_SMALL,AMD64,FOOBAR" inside /etc/grml/grml-live.local
+or invoke grml-live using the classes option: "grml-live -c
+GRMLBASE,GRML_SMALL,AMD64,FOOBAR ...".
More details regarding the class concept can be found in the documentation of
FAI itself (being available at /usr/share/doc/fai-doc/).
+[[X7]]
+[[classes]]
Available classes
-----------------
-Documentation to be done...
+The package selection part of the classes can be found in
+${GRML_FAI_CONFIG}/config/package_config whereas some further classes are defined for
+example in ${GRML_FAI_CONFIG}/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_FULL: full featured Grml, also known as the "normal", full grml as
+introduced in December 2011 (~350MB ISO size).
+
+* GRML_MEDIUM: medium sized Grml version, used to be known as grml-medium
+until December 2011 (~220MB ISO size).
+
+* GRML_SMALL: minimum sized Grml version, known as grml-small (~110MB ISO
+size).
+
+* GRML_XL: large size Grml version, used to be known as "full grml" until
+December 2011 (~700MB ISO size).
+
+* 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,...)
+
+* SOURCES: retrieve Debian source packages after installation. Files will be
+placed in the output directory under grml_sources.
+
+* XORG: providing important packages for use with a base grml-featured X.org
+setup

Files
-----
Notice that grml-live ships FAI configuration files that do not use the same
namespace as the FAI packages itself. This ensures that grml-live does not clash
with your usual FAI configuration, so instead of /etc/fai/fai.conf (package
-fai-client) grml uses /etc/grml/fai/fai.conf instead. For more details see
+fai-client) grml uses ${GRML_FAI_CONFIG}/fai.conf instead. For more details see
below. To get an idea how another configuration or example files could look like
check out /usr/share/doc/fai-doc/examples/simple/ (provided by Debian package
fai-doc). Furthermore /usr/share/doc/fai-doc/fai-guide.html/ch-config.html
/etc/grml/grml-live.conf
-Main configuration file for grml-live. All the important steps can be configured
-at this stage.
+Main configuration file for grml-live which should be considered as a reference
+configuration file only. Please use /etc/grml/grml-live.local for local
+configuration instead.
- /etc/grml/fai/fai.conf
+ /etc/grml/grml-live.local
+
+All the local configuration should go to this file. This file overrides any
+defaults of grml-live. Configurations via /etc/grml/grml-live.local are preferred
+over the ones from /etc/grml/grml-live.conf. If you want to override settings
+from /etc/grml/grml-live.local as well you have to specify them on the grml-live
+commandline.
+
+ ${GRML_FAI_CONFIG}/fai.conf
Main configuration file for FAI which specifies where all the configuration
-files and scripts for FAI/grml-live can be found. By default it is set to
-FAI_CONFIGDIR=/etc/grml/fai/config, a directory shipped by grml-live
-out-of-the-box so you shouldn't have to configure anything in this file.
+files and scripts for FAI/grml-live can be found. By default the configuration
+variables are FAI_CONFIG_SRC=file:///etc/grml/fai/config and
+GRML_FAI_CONFIG=/etc/grml/fai/config - both pointing to a directory shipped by
+grml-live out-of-the-box so you shouldn't have to configure anything in this
+file.
- /etc/grml/fai/make-fai-nfsroot.conf
+ ${GRML_FAI_CONFIG}/make-fai-nfsroot.conf
This file is used by make-fai-nfsroot(8) only. Usually you don't have to change
anything inside this file. If you want to modify NFSROOT though you can adjust
it there.
- /etc/grml/fai/NFSROOT
+ ${GRML_FAI_CONFIG}/NFSROOT
This file specifies the package list for creating the NFSROOT.
- /etc/grml/fai/apt/sources.list
-
-This file specifies which mirrors should be used for retreiving the Debian
-packages used for creating the main chroot (including all the software you would
-like to see included). If you want to use a local mirror you either have to
-adjust this file or use the GRML_LIVE_SOURCES variable inside
-/etc/grml/grml-live.conf which modifies /etc/grml/fai/apt/sources.list
-on-the-fly then.
-
- /etc/grml/fai/config/
+ ${GRML_FAI_CONFIG}/config/
The main directory for configuration of FAI/grml-live. More details below.
- /etc/grml/fai/config/class/
+ ${GRML_FAI_CONFIG}/config/class/
This directory contains files which specify main configuration variables for the
FAI classes.
- /etc/grml/fai/config/debconf/
+ ${GRML_FAI_CONFIG}/config/debconf/
This directory provides the files for preseeding/configuration of debconf
through files.
- /etc/grml/fai/config/hooks/
+ ${GRML_FAI_CONFIG}/config/hooks/
This directory provides files for customising the build process through hooks.
Hooks are user defined programs or scripts, which are called during the
installation process.
- /etc/grml/fai/config/package_config/
+ ${GRML_FAI_CONFIG}/config/package_config/
Directory with lists of software packages to be installed or removed. The
different classes describe what should find its way to your ISO. When running
-"grml-live -c GRMLBASE,GRML_SMALL,I386 ..." only the configuration of GRMLBASE,
-GRML_SMALL and and I386 will be taken. If you use 'grml-live -c
-GRMLBASE,GRML_SMALL,I386,FOOBAR ...' then the files of GRMLBASE, GRML_SMALL,
-I386 **plus** the files from FOOBAR will be taken. So just create a new class to
+"grml-live -c GRMLBASE,GRML_SMALL,AMD64 ..." only the configuration of GRMLBASE,
+GRML_SMALL and and AMD64 will be taken. If you use 'grml-live -c
+GRMLBASE,GRML_SMALL,AMD64,FOOBAR ...' then the files of GRMLBASE, GRML_SMALL,
+AMD64 **plus** the files from FOOBAR will be taken. So just create a new class to
adjust the package selection according to your needs. Please notice that the
directory GRMLBASE contains a package list defining a minimum but still
reasonable package configuration.
- /etc/grml/fai/config/scripts/
+ ${GRML_FAI_CONFIG}/config/scripts/
Scripts for customising the ISO within the build process.
- /etc/grml/fai/files/

Available log files
-------------------
-grml-live itself logs to /var/log/grml-live.log. Unless you set ZERO_LOGFILE in
-/etc/grml/grml-live.conf the output is appended to the file. If you set the
-ZERO_LOGFILE configuration option the logfile will be truncated on each new
-invocation of grml-live.
-
-The FAI part of grml-live logs to /var/log/fai/$HOSTNAME/ - so the
-default being /var/log/fai/grml/.
+Starting with grml-live version 0.17.0 you should find log files in a directory
+named 'grml_logs' in the output directory (next to grml_isos, grml_chroot,...).
-If you are using the grml-live buildd you will find the logs of the grml-live
-run at /var/log/grml-buildd.stdout and /var/log/grml-buildd.stderr.

+How do I deploy grml-live on a plain Debian installation?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The easiest way to get a running grml-live setup is to just use Grml.
+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 squeeze (6.0) with debian-backports
+enabled. (This is important for squashfs-tools.)
+
+What we want: build a Grml ISO based on Debian/wheezy for the amd64 architecture
+using grml-live.

+What is $GRML_FAI_CONFIG?
+~~~~~~~~~~~~~~~~~~~~~~~~~
-or check out the link:http://www.informatik.uni-koeln.de/fai/[FAI-homepage] for
-further details.
+The variable '$GRML_FAI_CONFIG' is pointing to the directory /etc/grml/fai by
+default. To provide you a maximum of flexibility you can set up your own
+configuration directory (e.g. based on /etc/grml/fai) and use this directory
+running grml-live with the '-D <config_dir>' option. Now '$GRML_FAI_CONFIG'
+points to the specified directory instead of using /etc/grml/fai and all the
+configuration files, scripts and hooks will be taken from your
+'$GRML_FAI_CONFIG' directory.
+[[how-to-debug]]
I've problems with the build process. How to start debugging?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Check out the logs inside /var/log/fai/... If you don't have the time to debug
-the problem in further detail or don't know how to proceed just send a copy of
-your config, logs and the commandline with a short problem description to
-<mika@grml.org>:
+Check out the logs inside the directory 'grml_logs' next to your grml_chroot,
+grml_isos,... directories.

+grml-live you can get commercial support via
+link:http://grml-solutions.com/[Grml Solutions].
+[[install-local-files]]
+How do 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/
+ grml-live ...
+
+[[local-debian-mirror]]
Can I use my own (local) Debian mirror?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Sure. Just adjust the variables GRML_LIVE_SOURCES and FAI_DEBOOTSTRAP (if not
-already using NFSROOT's base.tgz) inside /etc/grml/grml-live.conf according to
-your needs. Please don't forget that you should use the grml servers as well
-(see default configuration) so all the grml packages can be downloaded as well.
+Yes. Set up an according sources.list configuration as class file in
+${GRML_FAI_CONFIG}/config/files/etc/apt/sources.list.d/ and adjust the variable
+FAI_DEBOOTSTRAP (if not already using NFSROOT's base.tgz) inside
+/etc/grml/grml-live.conf[.local]. If you're setting up your own class file don't
+forget to include the class name in the class list (grml-live -c ...).
-If you want to use a local (for example NFS mount) mirror additionally, just
-adjust MIRROR_DIRECTORY and MIRROR_SOURCES inside /etc/grml/grml-live.conf as
-well.
+If you want to use a local (for example NFS mount) mirror additionally then
+adjust MIRROR_DIRECTORY in /etc/grml/grml-live.conf[.local] as well.
-Unless you specify GRML_LIVE_SOURCES and/or FAI_DEBOOTSTRAP the default from
-/etc/grml/fai/apt/sources.list and /etc/grml/fai/make-fai-nfsroot.conf will be
-taken. If you customise the variables in /etc/grml/grml-live.conf then the two
-files will be adjusted during runtime automatically.
+If you want to use a HTTP Proxy (like apt-cacher-ng), set APT_PROXY. Example:
-If MIRROR_DIRECTORY and MIRROR_SOURCES are specified the local mirror will be
-taken as first entry in the generated sources.list so it's prefered over
-non-local mirrors. Using a fallback mirror (via providing several mirrors in
-GRML_LIVE_SOURCES as used by default) is a recommended setting.

+[[add-additional-debian-packages]]
How do I add additional Debian package(s) to my CD/ISO?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
and specify it when invoking grml-live then:
- # grml-live -c GRMLBASE,GRML_SMALL,I386,MIKA
+ # grml-live -c GRMLBASE,GRML_SMALL,AMD64,MIKA
+[[reset-grml-live-configuration]]
I fscked up my grml-live configuration. How do I reset it to the defaults?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
rm -rf /etc/grml/fai /etc/grml/grml-live.conf
dpkg -i --force-confnew --force-confmiss /path/to/grml-live_..._all.deb
-[NOTE]
-
-If you don't control your /etc using a version control system (VCS) yet it's a
-good chance to start using it now. Check out

+[[create-a-base-tgz]]
+How do I create a base.tgz?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
-How do I create a base.tgz for use as NFSROOT?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+First of all create the chroot using debootstrap:
-First of all build the chroot system:
+ BASECHROOT='/tmp/basefile'
+ debootstrap squeeze "$BASECHROOT" http://cdn.debian.net/debian
+ tar -C "$BASECHROOT" --exclude='var/cache/apt/archives/*.deb' -zcf base.tar.gz ./
- mkdir /tmp/nfsroot && cd /tmp/nfsroot
- debootstrap etch /tmp/nfsroot/ http://ftp.de.debian.org/debian
- tar zcf base.tgz ./
+[TIP]
+By default debootstrap builds a chroot matching the architecture of the running
+host system. If you're using an amd64 system and want to build an i386 base.tgz
+then invoke debootstrap using the '--arch i386' option. Disclaimer: building an
+AMD64 base.tgz won't work if you are using a 32bit kernel system of course.
-Then check out where your NFSROOT is located:
+Then move the base.tar.gz to /etc/grml/fai/config/basefiles/$CLASSNAME.tar.gz.
+Use e.g. I386 as $CLASSNAME for i386 chroots and AMD64 for amd64 chroots.
- # grep '^NFSROOT' /etc/grml/fai/make-fai-nfsroot.conf
- NFSROOT=/grml/fai/nfsroot
-
-So as /grml/fai/nfsroot is your NFSROOT place the file under
-/grml/fai/nfsroot/live/filesystem.dir/var/tmp/:
-
- mv base.tgz /grml/fai/nfsroot/live/filesystem.dir/var/tmp/base.tgz
-
-or even better use /etc/grml/fai/config/basefiles/$CLASSNAME.tar.gz instead.
-Use I386 as $CLASSNAME for i386 builds and AMD64 for amd64 builds.
-
-Now running "grml-live ..." will use this file as main system instead of
-executing debootstrap. Check out the output for the following lines if using
-NFSROOT:
+Now executing grml-live should use this file as base system instead of executing
+debootstrap. Check out the output for something like:
[...]

- Unpacking Debian base archive
- Extracting /grml/fai/nfsroot/live/filesystem.dir/var/tmp/base.tgz
- Calling task_mirror

+[[basetgz]]
+How do I create a base tar.gz (I386.tar.gz or AMD64.tar.gz)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Don't forget to restart approx (/etc/init.d/approx restart). That's it.
-All downloaded files will be cached in /var/cache/approx now.
+Execute the following commands (requires root):
-I've a question which isn't answered by this document
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ ARCH='amd64' # replace with i386 if necessary
+ SUITE='squeeze' # using the current stable release should always work

+ tar zcf ../"${ARCH}".tar.gz *
-Don't hesitate to ask on IRC (channel #grml on irc.freenode.org) or just drop me
-a mail: <mika@grml.org>
+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).
