[Fedora-i18n-list] i18n LANG setting in FC3

[Jamie Larsen]

I changed the LANG setting in /etc/sysconfig/i18n to

LANG=zh_TW.Big5 (or zh_TW.UTF-8) from the default LANG=en_US.UTF-8

An "echo $LANG" shows that the LANG setting has been changed to the new 
value.  However, this change is effective only in that session.  When I 
start a new shell, the LANG setting goes back to the default value.  Is 
there any script in FC3 that overwrites i18n settings?
