Disable Wired Ethernet at Boot
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.
