Setbacks in Debian land

Another 'reminder' post :
Allright, you're ready to install a Debian distro right from the internet... Things are going well until the program chooses the lan to install itself instead of your standard pppoe ADSL connection! Meaning either you didn't read the info displayed or your modem response to DHCP Discover is privileged... (probably both of them)

Ok, stay calm and wait for the end of the procedure.
pppoeconf will not be sufficient to save the day. You'll have to edit the /etc/network/interfaces, comment out 'iface eth0 inet dhcp' and add 'iface eth0 inet ppp provider . Bring up eth0... That's all :)
