I have users on my system using several different locales.
When i upgraded to redhat-6.1 some of them reported that
they could no longer set locale with LANG or LC_* as they
used to. After looking around a bit i noticed that the
LC_ALL variable is set in /etc/sysconfig/i18n which
overrides all the other settings. I would say this is
counter-intuitive to the user to need to unset LC_ALL to
make their old .bash_profiles work. I would like to see
that only LANG (the default lang that can be overridden by
LC_*) was set in /etc/syconfig/i18n
This will be fixed in the next installer release; it will not
write a 'LC_ALL' value to /etc/sysconfig/i18n.
