override.conf

# what's more frustrating than using `screen` to a serial console then running `less` or `vim` and having it
# not use your full window width & height like a NORMAL ***ING TERMINAL EMULATOR

# this belongs in /etc/systemd/system/serial-getty\@ttyS0.service.d/override.conf 
# If your terminal is something other ttyS0, adjust as needed.
# This is for Systemd (Debian Jessie and above, ubuntu Xenial/ Zesty, etc.
# There's a non-systemd equivalent in /etc/login.defs I think
