#Script Name : interactive_setup
|
|
#Description : This script guides you through creating a custom container on UnifiOS 3.0+ using systemd-nspawn.
|
|
# It includes steps for configuring the container, ensuring persistence across firmware updates,
|
|
# and installing custom services such as pihole (Not Yet) or adguard home.
|
|
# The process involves installing systemd-container and debootstrap and using them to create
|
|
# a base debian system in /data/custom/machines directory.
