rofi-netctl

#!/usr/bin/env bash
# This is just a very simple and naive interface to netctl
# It works for what I need for now
# It is desirable to be able to manage netctl-auto via systemd w/o rp
# See https://wiki.archlinux.org/index.php/Polkit#Allow_management_of_individual_systemd_units_by_regular_users
# This scripts requires the above to be implemented
