network/interfaces mapping

[sergio <debian-russian@sergio.spb.ru>]

Граждане, обясните мне пожайуста почему:
$ /etc/network/map-scheme wifi
YANKA
$ sudo ifup -v wifi
Running mapping script /etc/network/map-scheme on wifi
Ignoring unknown interface wifi=YANKA.
$

всё сделал как в мане написано.. имхо. или я чего-то не понимаю..
