Description: 
 grml-live  - build system for creating a grml (based) live-cd
Changes: 
 grml-live (0.0.10) unstable; urgency=low
 .
   * Drop patches which are part of FAI 3.2.3 now. Depend on
     FAI version 3.2.3 therefor.
   * FAI 3.2.3 has a new log schema, adjusted grml-live accordingly.
     Quoting the NEWS file of FAI:
     - LOGDIR is now /var/log/fai/$HOSTNAME/$FAI_ACTION_date+time
     - LOGDIR is /tmp/fai during an installation (not dirinstall), and
       will be copied to the path above at the end of an installation
   * Log the executed FAI, squashfs and mkisofs command lines to
     /var/log/grml-live.log.
   * New option '-C <configuration_file>' for specifying a configuration
     file. Needs heavy testing though, because the files are updated
     during runtime it isn't as easy as expected to be. :-/
   * Support $ZERO_FAI_LOGFILE inside grml-live configuration for removing
     old FAI logs.
   * Do not enable apt-listbugs if the binary is not available.
     [Testing: issue340]
   * Add keychain package to GRML_SMALL.
   * Add new packages to GRML_MEDIUM:
     - grml-live
     - keychain
     - lzma-modules-2.6.23-grml
     - squashfs-modules-2.6.23-grml (we build the module external now)
   * Add new packages to GRML_FULL:
     - aosd-cat
     - grml-live
     - lzma-modules-2.6.23-grml
     - squashfs-modules-2.6.23-grml (we build the module external now)
   * Support loading of squashfs module via
     /etc/grml/fai/live-initramfs/grml-script.init-top
   * Make sure we have pinning for grml-stable and grml-testing
     repositories via /etc/grml/fai/apt/preferences, not matter where
     the packages come from (web vs. local mirror/cache for example).
   * Remove base.tgz from chroot directory.
   * Do not create /etc/sysconfig/network-scripts and
     /etc/sysconfig/provider any longer in cleanup script.
   * Fix typo in bootsplash f3 (thanks, jimmy).
   * Switch order of 'lang=us apm=power-off' to 'apm=poweroff' in
     isolinyx/syslinux/grub configuration because getbootparam
     of grml-autoconfig requires a whitespace inside /proc/cmdline.
   * Support grml2ram bootoption inside isolinyx/syslinux/grub
     configuration.

No, apt-get install apt-listbugs wants a bunch of packages:

After unpacking 8790kB of additional disk space will be used.

Closing the bugreport, http://hg.grml.org/grml-live/rev/bbf7a227376b should fix 
the bug for all upcoming ISOs.

thanks for your report and feedback, Alexander!

Wouldn't it be better to include apt-listbugs?
