kickstart LANG issue

[Tom Brown <tom ng23 net>]

Hi

In my kix file i have LANG set to the following

lang en_GB
langsupport --default=en_GB en_GB

however on install the box is

# env | grep LANG
LANG=en_GB.UTF-8

# cat /etc/sysconfig/i18n
LANG="en_GB.UTF-8"
SUPPORTED="en_GB.UTF-8:en_GB:en"

How can i make it so the default LANG is en_GB and not UTF-8 ?

thanks
