Hi! All, It has become necessary to move this box to a different room where a wired ethernet connection is impractical. So, I'm going wireless with it. USB. No problem with that, but . . . What's the easiest way to prevent the wired ethernet (built-in on motherboard) from starting up? I was thinking of just commenting its stanza out of /etc/network/interfaces. Any other more practical (or proper) way that's 100% easily reversable?
FYI: This system is an atypical install of Stretch. Started as terminal only, converted to sysvinit, then added what I wanted. No desktop was ever installed. Only X and a window manager -- Openbox. Boots to terminal where login occurs, then startx, if desired. No display/login manager, no network manager of any kind. Only udev running. No other systemd stuff is. Everything has changed since I last did something like this 10 years ago. So, I just want to check to be sure. Thanks. B
