Bug#570341: console-setup: will not configure the console when installed with apt

[Sven Joachim <svenjoac@gmx.de>]

Package: console-setup
Version: 1.53
Severity: normal

When installing console-setup with apt, it will never configure the
console, even if you do it on tty1:

,----
| Richte console-setup ein (1.53) ..
| We are not on the Linux console, the console is leaved unconfigured.
`----

(You want to s/leaved/left/ in the error message, I'm not going to file
another bugreport for that.)

That's because apt sets up a special pty for dpkg to enable logging its
output, so dpkg is not running on tty1.
