-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 ./

-So as /grml/fai/nfsroot is your NFSROOT place the file under

+  debootstrap squeeze "$BASECHROOT" http://cdn.debian.net/debian

-  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.

+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.
