I just created a package namend grml-fixes. From the package description:
This package includes some fixes for the grml system.
There are for example some problems with (upstream/debian)
shell scripts and the zsh. Therefor this package fixes
them until they are fixes upstream.
Now we are again a step closer to the big goal to be once able to run 'apt-get install grml' on a plain Debian system and get a full-featured grml-system out of it. :-)
