Bug#65933: Setting clock to UTC sometimes doesn't work

[Niccolo Rigacci <rigacci@iname.com>]

Package: boot-floppies
Version: 2.2.15
Subject: Setting


When dbootstrap executes "Configure the Base System", if you
choose to set the clock to local time, the string "UTC=no" is
placed in /etc/default/rcS. This is OK.

But if you re-execute "Configure the Base System" and choose to
set the clock to UTC, the value in /etc/default/rcS is not
updated.

I suggest to place an "else" clause in configure_timezone_step2()
function in boot-floppies/utilities/dbootstrap/tzconfig.c
