[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
grml-live out-of-the-box so you shouldn't have to configure anything in this
file.
- ${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.
-
- ${GRML_FAI_CONFIG}/NFSROOT

-This file specifies the package list for creating the NFSROOT.

${GRML_FAI_CONFIG}/config/
The main directory for configuration of FAI/grml-live. More details below.

Of course using grml-live on a plain, original Debian installation is supported
as well. So there we go.

What we want: build a Grml ISO based on Debian/wheezy for the amd64 architecture
using grml-live.

[[create-a-base-tgz]]
-How do I create a base.tgz for use as NFSROOT?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-First of all build the chroot system:
+How do I create a base.tgz?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
- mkdir /tmp/nfsroot && cd /tmp/nfsroot
- debootstrap squeeze /tmp/nfsroot/ http://cdn.debian.net/debian
- tar zcf base.tgz ./
+First of all create the chroot using debootstrap:
-Then check out where your NFSROOT is located:
+ BASECHROOT='/tmp/basefile'
+ debootstrap squeeze "$BASECHROOT" http://cdn.debian.net/debian
+ tar -C "$BASECHROOT" --exclude='var/cache/apt/archives/*.deb' -zcf base.tar.gz ./
- # 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:
+[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.
