Options
-------
+ -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
+crosscompiling (like building a ppc system on x86) isn't possible due to the
+nature and the need of working in a chroot.
+
-c **CLASSES**::
Specify the CLASSES to be used for building the ISO via FAI. By default only
-the classes GRMLBASE and I386 are assumed, resulting in a small base system
-(being about ~150MB total ISO size) for x86 (32bit).
+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.
-F::
-i **ISO_NAME**::
-Specify name of ISO which will be available inside $TARGET_DIRECTORY/grml_isos
+Specify name of ISO which will be available inside $OUTPUT_DIRECTORY/grml_isos
by default.
+ -o **OUTPUT_DIRECTORY**::
+
+Main output directory of the build process of FAI. Some directories are created
+inside this target directory, being: grml_cd (where the files for creating the
+ISO are located, including the compressed squashfs file), grml_chroot (the
+chroot system) and grml_isos (where the resulting ISO is stored).
+
-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,
-stable, testing, unstable.

- -t **TARGET_DIRECTORY**::
+ -t **TEMPLATE_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).
+Specify place of the templates used for building the ISO. By default
+(and if not manually specified) this is /usr/share/grml-live/templates/.
-v **VERSION_NUMBER**::
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 -t /home/mika/grml-live
+ # grml-live -c GRMLBASE,GRML_SMALL,I386 -o /home/mika/grml-live
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 -t /tmp -c GRMLBASE,I386 -s sid -i grml_0.0-3.iso
+ # grml-live -o /tmp -c GRMLBASE,GRML_SMALL,I386 -s sid -i grml_0.0-3.iso
[NOTE]
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 $CHROOT_TARGET,
-$BUILD_TARGET and $ISO_TARGET if you plan to create more persistent output. :)

Main features of grml-live
--------------------------
The main and base class provided by grml-live is named GRMLBASE. It's strongly
recommended to **always** use the class GRMLBASE when building an ISO using
-grml-live, as well as the architecture dependend class which provides the kernel
-(being 'I386' for x86_32 currently only). The following files and directories
-are relevant for class GRMLBASE by default:
+grml-live, as well as the architecture dependent class which provides the kernel
+(being 'I386' for x86_32 and 'AMD64' for x86_64) and a GRML_* class (like
+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
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,I386" inside /etc/grml/grml-live.conf to
-CLASSES="GRMLBASE,I386,FOOBAR" or invoke grml-live using the classes option:
-"grml-live -c GRMLBASE,I386,FOOBAR ...".
+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 ...".
More details regarding the class concept can be found in the documentation of
FAI itself (being available at /usr/share/doc/fai-doc/).

Files
-----
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,I386 ..." only the files from the directories GRMLBASE
-and I386 will be taken, if you use 'grml-live -c GRMLBASE,I386,FOOBAR ...' then
-the files of GRMLBASE, I386 **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.
+"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
+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.

I fscked up my grml-live configuration. How do I reset it to the defaults?

+[NOTE]
+
+Notice that you can also use /etc/grml/fai/config/basefiles/$CLASSNAME.tar.gz if
+you prefer to use /etc as the main configuration directory instead of
+/path/to/nfsroot/.... (Thanks to Thomas Lange for the tip.)
+
+Set up apt-cacher for use with grml-live
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Make sure /etc/grml/grml-live.conf provides according GRML_LIVE_SOURCES and
+FAI_DEBOOTSTRAP:
+
+ # cat /etc/grml/grml-live.conf
+ [...]
+ GRML_LIVE_SOURCES="
+ deb http://localhost:3142/deb.grml.org grml-stable main
+ deb http://localhost:3142/deb.grml.org grml-testing main
+ deb http://localhost:3142/ftp.de.debian.org/debian etch main contrib non-free
+ "
+ [...]
+ FAI_DEBOOTSTRAP="etch http://localhost:3142/ftp.de.debian.org/debian etch main contrib non-free"
+
+Make sure apt-cacher is running (/etc/init.d/apt-cacher restart). That's it.
+All downloaded files will be cached in /var/cache/apt-cacher/ now.
