Pacific vs. Pacific-New

While configuring tzdata, the debconf dialog asked:

 Please select the city or region corresponding to your time zone.
 Time zone: 
Huh? WTF is Pacific-New? Looking around one can find #524046 from 2009, where the "pacificnew" zonefile got included without any debate. In fact, the zonefiles appear to be equal in every detail:
$ ls -ligo /usr/share/zoneinfo/US/Pacific{,-New}
352130 -rw-r--r-- 2 2819 Oct 31 15:49 /usr/share/zoneinfo/US/Pacific
352130 -rw-r--r-- 2 2819 Oct 31 15:49 /usr/share/zoneinfo/US/Pacific-New
And even their checksums match.1) That being established, I think it's safe to just choose "Pacific" and be done with it. Who knows when they will remove the Pacific-New zonefile again...

1) Of course they match, they have the same inode, d'oh!
