-Clean up output directories before attempting the build. Packs the chroot
-into a tar archive, and removes chroot and ISO build directories before exiting.
+Clean up all output directories before running the build process. After finishing,
+clean up the Chroot target and Build target directories.
-a **ARCHITECTURE**::
-s **SUITE**::
-Specify the Debian suite you want to use for your live-system. Defaults to
-"squeeze" (being current Debian/stable). Supported values are: etch, lenny,
-squeeze, sid. Debian "squeeze" requires a recent base.tgz
+Specify the Debian suite you want to use for your live-system. If unset defaults
+to "testing". Supported values are: stable, testing, unstable (or their
+corresponding release names like "wheezy"). Please be aware that recent Debian
+suites might require a recent base.tgz
(${GRML_FAI_CONFIG}/config/basefiles/$CLASSNAME.tar.gz) or a recent version of
debootstrap.
Specify place of the templates used for building the ISO. By default
(and if not manually specified) this is /usr/share/grml-live/templates/.
- -T **CHROOT_ARCHIVE**::
-
-Unpack chroot tar archive before starting. Most useful in combination with
--A and -b or -u.
-
-u::

[NOTE]
-If you have enough 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
* DEBORPHAN: get rid of all packages listed in output of deborphan
+* FRESHCLAM: execute freshclam (if it's present) to update clamav definitions
+(increases resulting ISO size ~70MB). By default it's skipped to avoid bigger
+ISO size.
+
* 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
grml-live out-of-the-box so you shouldn't have to configure anything in this
file.

FAQ
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).
+What we have: plain, original Debian wheezy (7.x).
What we want: build a Grml ISO based on Debian/wheezy for the amd64 architecture
using grml-live.

-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 squeeze /tmp/nfsroot/ http://cdn.debian.net/debian
- tar zcf base.tgz ./
-
-Then check out where your NFSROOT is located:
-
- # grep '^NFSROOT' /etc/grml/fai/make-fai-nfsroot.conf
- NFSROOT=/grml/fai/nfsroot
+How do I create a base.tgz?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
-So as /grml/fai/nfsroot is your NFSROOT place the file under
-/grml/fai/nfsroot/live/filesystem.dir/var/tmp/:
+First of all create the chroot using debootstrap:
- mv base.tgz /grml/fai/nfsroot/live/filesystem.dir/var/tmp/base.tgz
+ BASECHROOT='/tmp/basefile'
+ debootstrap wheezy "$BASECHROOT" http://ftp.debian.org/debian
+ tar -C "$BASECHROOT" --exclude='var/cache/apt/archives/*.deb' -zcf base.tar.gz ./
-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:
+[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.
