Bug#37307: bad logic in /usr/sbin/tzconfig

[Stephen Lee <sl2001@iname.com>]

Package: libc6
Version: 2.1.1-2

/usr/sbin/tzconfig:

>TIMEZONE="`/usr/bin/tzselect`"
>if [ -z "$TIMEZONE" ]; then
>    echo "$TIMEZONE" > /etc/timezone
>    rm -f /etc/localtime ; ln -s /usr/share/zoneinfo/$TIMEZONE /etc/localtime
>else
>    echo "$OLDTIMEZONE" > /etc/timezone
>    rm -f /etc/localtime ; ln -s /usr/share/zoneinfo/$OLDTIMEZONE
/etc/localtime
>fi

This does not config the correct timezone when tzselect successfully returns.

I am using Debian potato.
