Bug description:
[ Impact ]
Users can select some time zones in debconf that the tzdata debconf
script will replace on the next run. See "Original report" for more
explanation. Either those time zones should not be selectable in
debconf or they should not be replaced.
[ Test Plan ]
Select US/Central as time zone and run dpkg-reconfigure:
```
sudo ln -sf /usr/share/zoneinfo/US/Central /etc/localtime
echo "US/Central" | sudo tee /etc/timezone
sudo dpkg-reconfigure -fnoninteractive tzdata
```
The output of dpkg-reconfigure should say that the current default
time zone is still US/Central.
Besides this manual test, test_timezone_conversions is backported to
check that there are no timezones which can be selected, but will be
converted.
[ Where problems could occur ]
Besides added tests, the debconf part of tzdata is touched and could
cause issues. The change does not touch the actual timezones.
[ Original report ]
Other than the fact that Chicago, Illinois is in US Central Timezone,
I have no relationship to Chicago. I am not in Chicago. I do not want
to be in Chicago. I am in the Central Timezone. I am physically closer
to other cities mentioned in tzdata. Selecting America/Chicago versus
US/Central is not easier for me nor is it more intuitive. I
understand that the upstream tzdata package goes a long way in
documenting all of the weirdness associated with timezones and
different localities' treatment of timezones and daylight "savings"
time. However, from an end-user perspective, the distribution should
place no special importance or preference on one timezone
specification or another. Likewise, if a user chooses a timezone, the
system should never change it.
To reproduce the issue:
# Manually select US/Central
me@ubuntu:~$ sudo dpkg-reconfigure tzdata
[sudo] password for me:
Current default time zone: 'US/Central'
Local time is now: Wed Apr 27 16:05:02 CDT 2011.
Universal Time is now: Wed Apr 27 21:05:02 UTC 2011.
# Validation that selection was accepted
me@ubuntu:~$ cat /etc/timezone
US/Central
me@ubuntu:~$ md5sum /etc/localtime /usr/share/zoneinfo/US/Central
