Assunto: Re: [DNG] Quick start guide to uprading to Devuan and configuringminimalism
After the reboot (half way through the instructions), those with a Wifi
network card won't be able to continue (install xfce4, and so on...)
because they won't be in x-windows anymore, and the network-manager app
needs x-windows to work, ergo, no internet connection :(
