allows building a 32bit system on a 64bit host (though you can't build a 64bit
system on a 32bit system/kernel of course). Please notice that real
crosscompiling (like building a ppc system on x86) isn't possible due to the

architecture) are assumed. Additionally you can specify a class providing a
(grml-)kernel (see <<classes,the 'CLASSES' section in this document>> for
details about available classes). So instead of GRML_FULL you can also use e.g.
Specify the Debian suite you want to use for your live-system. If unset defaults

suites might require a recent base.tgz
(${GRML_FAI_CONFIG}/config/basefiles/$CLASSNAME.tar.gz) or a recent version of
debootstrap.
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 dependent class which provides the kernel
-(being 'I386' for x86_32 and 'AMD64' for x86_64) and a GRML_* class (like
-GRML_SMALL or GRML_FULL). The following files and directories are
-relevant for class GRMLBASE by default:
+(being 'I386' for x86_32, 'AMD64' for x86_64 and 'ARM64' for arm64) and a GRML_*
+class (like GRML_SMALL or GRML_FULL).
+The following files and directories are relevant for class GRMLBASE by default:
${GRML_FAI_CONFIG}/config/scripts/GRMLBASE/
${GRML_FAI_CONFIG}/config/debconf/GRMLBASE
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 (or extend an
-existing one). For example if you want to use your own class named "FOOBAR" just
-set CLASSES="GRMLBASE,GRML_SMALL,AMD64,FOOBAR" inside /etc/grml/grml-live.local
-or invoke grml-live using the classes option: "grml-live -c
-GRMLBASE,GRML_SMALL,AMD64,FOOBAR ...".

+your amd64 build, et CLASSES="GRMLBASE,GRML_SMALL,AMD64,FOOBAR" inside
+/etc/grml/grml-live.local or invoke grml-live using the classes option:
+"grml-live -c GRMLBASE,GRML_SMALL,AMD64,FOOBAR ...".
More details regarding the class concept can be found in the documentation of
FAI itself (being available at /usr/share/doc/fai-doc/).
* DEBORPHAN: get rid of all packages listed in output of deborphan
-* FILE_RC: instead of using systemd as init system use file-rc instead. file-rc
-was the init system used by Grml until and including stable release 2014.11,
-starting with beginning of 2016 Grml switched to systemd instead. If you want to
-build a live system in the old style using file-rc instead of systemd then enable
-this class. Please notice that the Grml team no longer provides support for it
-though.
-
* 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.
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 stretch (9.x).
+What we have: plain, original Debian bookworm (v12).
-What we want: build a Grml ISO based on Debian/stretch for the amd64 architecture
+What we want: build a Grml ISO based on Debian/bookworm for the amd64 architecture
using grml-live.

First of all create the chroot using debootstrap (requires root):
BASECHROOT='/tmp/basefile' # path where the chroot gets generated
- SUITE='stretch' # using the current stable release should always work
- debootstrap --exclude=info,tasksel,tasksel-data "$SUITE" "$BASECHROOT" http://ftp.debian.org/debian
+ SUITE='bookworm' # using the current stable release should always work
+ debootstrap --exclude=info,tasksel,tasksel-data,isc-dhcp-client,isc-dhcp-common "$SUITE" "$BASECHROOT" http://deb.debian.org/debian
tar -C "$BASECHROOT" --exclude='var/cache/apt/archives/*.deb' -zcf "${SUITE}".tar.gz ./
[TIP]
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.
+Also building an ARM64 base.tgz requires an arm64 system.
Finally place the generated tarball in /etc/grml/fai/config/basefiles/ (note
that it needs to be uppercase letters matching the class names, so: e.g.
-AMD64.tar.gz for amd64 and I386.tar.gz for i386).
+AMD64.tar.gz for amd64, I386.tar.gz for i386 or ARM64.tar.gz for arm64).
Then executing grml-live should use this file as base system instead of executing
debootstrap. Check out the output for something like:
