How to get your own live-cd - the easy, fast and simple way
-----------------------------------------------------------
-To get a small, Debian-stable and grml based live-cd:
+To get a small, Debian-stable and grml based live-cd using /dev/shm/
+as build and output directory:
+
+ # grml-live
- # TARGET="/grml/grml_uncompressed"
- # CDDIR="/grml/grml_cd"
- # grml-live -c GRML -t $TARGET
- # mksquashfs $TARGET/* $CDDIR/live/grml.squashfs -noappend
- # cd $CDDIR

- -boot-info-table -c boot/isolinux/boot.cat \
- -b boot/isolinux/isolinux.bin -o /grml/grml.iso .
+[NOTE]
-(TODO: provide the content of /grml/chroot/grml_cd through the package
-grml-live, in the meanwhile get the content from a current grml-ISO)
+If you have about 700MB of free space inside /dev/shm (being a tmpfs, usually
+you 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. :)
The class concept
-----------------
according to your needs. This gives you flexibility and strength without losing
the simplicity in the build process.
-The main and base class provided by grml-live is named GRML. It's strongly
-recommended to **always** use the class GRML when building an ISO using
+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 (being 'I386' for x86_32
currently only). The following files and directories are relevant for class GRML
by default:
- /etc/grml/fai/config/scripts/GRML/
- /etc/grml/fai/config/debconf/GRML
- /etc/grml/fai/config/class/GRML.var
- /etc/grml/fai/config/hooks/instsoft.GRML
- /etc/grml/fai/config/package_config/GRML

+ /etc/grml/fai/config/class/GRMLBASE.var
+ /etc/grml/fai/config/hooks/instsoft.GRMLBASE
+ /etc/grml/fai/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. For example
-if you want to use your own class named "FOOBAR" just extend CLASSES="GRML" inside
-/etc/grml/grml-live.conf to CLASSES="GRML,FOOBAR" or invoke grml-live using
-the classes option: "grml-live -c GRML,FOOBAR ...".

/etc/grml/fai/apt/sources.list
File with lists of software packages to be installed or removed. The different
classes describe what should find its way to your ISO. When running 'fai -v -C
-/etc/grml/fai -cGRML dirinstall ...' only the files from the directory GRML/
-will be taken, if you use 'fai -v -C /etc/grml/fai -cGRML,FOOBAR dirinstall ...'

-create a new class to adjust it to your needs. Please notice that the directory

-configuration.

This directory provides the files used for building the initramfs/initrd via
* any Debian based system should be sufficient (if not please send a bug
report), for example a grml2hd harddisk installation ships all you need
-* enough free disk space, at least 700MB are required for a minimal grml-live
-run (~400MB for the chroot [$CHROOT_TARGET], ~150MB for the build target
-[$BUILD_TARGET] and ~150MB for the resulting ISO [$ISO_TARGET]).

+run (\~400MB for the chroot [$CHROOT_TARGET], \~150MB for the build target
+[$BUILD_TARGET] and \~150MB for the resulting ISO [$ISO_TARGET] plus some
+temporary files)
* fast network access for retreiving the Debian packages used for creating the
chroot (check out "local mirror" and "NFSROOT" to workaround this problem as far
Known TODOs
-----------
-* extend the grml-live wrapper script so it runs all the necessary command in a
-single run (boot/isolinux, mksquashfs and mkisofs stuff is missing currently)
+* do not use /dev/shm/ als default target directory (which one do we want to use
+instead?)
-* really support signed apt repositories
+* add support for amd64 [gebi?] + ppc [formorer?] (and identify all packages
+that are arch specific so we have a clean package list in all classes)
+
+* support different grml-flavours through classes right out-of-the-box (being:
+grml, grml64, grml-small for at least x86, amd64 and ppc)
+
+* support setting grml-live configuration on the command line to provide
+different flavours using the commandline only
+
+* really support signed apt repositories (currently it's deactivated via fai's
+dirinstall for some packages)
* explain (and provide configuration for) the use of NFSROOT
* support setting stuff like ISO name, version,... (especially for stuff inside
x86_files/boot/isolinux)
-* identify all packages that are arch specific
+* support "final builds" (including stuff like md5sums)
-* support different flavours and architectures of Debian (currently it defaults
-to Debian/stable x86_32)
+* use hooks of FAI as far as possible in all grml-live scripts
-* use hooks of FAI in grml-live script?
-
-* the GRML class(es) should send output as used inside FAI as well (so it's not
-as verbose unless you specify it)
+* the grml-live class(es) should send output as used inside FAI as well (so it's
+not as verbose unless you specify it, make it configurable)
* provide possibility for cleanup of all created build directories
+* support hooks to further allow customisation of the build process
+
+* support nocolor-option for /etc/grml/fai/grml/grml_cleanup_chroot
