At the start of the install linuxmce asks me if my networking information is correct. It is and I tell it to continue. Later it asks if I want to run a DHCP server. I already have a server doing that for my network so I say no. A console window then appears and packages start being fetched and installed. It is at this point linuxmce decides its had enough of a working network connection and promptly disables it by adding a reference to eth0:0 in /etc/network/interfaces.
Why does it do this and how can I stop it?
