Stephen and others who have been following this thread or who has been having this problem after adding the Knoppix package repository to your sources.list file I found out the real reason why things get defaulted back to german.
The fix is much better / more elegant than my previous fix.
Here's what need to do:
You need to open and edit the following file:
/etc/init.d/knoppix-autoconfig
Look for the following section:
Simply change the "de" at the end to "us".Code:### localization
# Allow language specification via commandline. The default language
# will be overridden via "lang=de" boot commandline
LANGUAGE="$(getbootparam lang 2>/dev/null)"
[ -n "$LANGUAGE" ] || LANGUAGE="de"
This should fix the problem.
