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