change initial keyboard layout of Raspberry Pi

I used debian squeeze as my first try or the raspberry.
First thing I noticed is that the keyboard layout is UK. I am in Germany, so I need to switch this.

After some searching I found this method:
1) ensure you have internet connection (e.g. via ethernet)
2) type:

sudo apt-get install console-data console-tools debconf

After downloading and installing has finished a graphical menu appears.
3) Select “Select keymap from full list”
4) I chose “pc/qwertz/german/standard/latin1-no dead keys”

Work like a charm for me.

In case the installaion ends without the menu or you want to change the layout later again use:
sudo dpkg-reconfigure console-data
