# Automatic Service Start
#
# By default, this script automatically starts the Docker daemon and enables the docker
# service after installation if systemd is used as init.
#
# If you prefer to start the service manually, use the --no-autostart option:
#
# $ sudo sh install-docker.sh --no-autostart
#
# Note: Starting the service requires appropriate privileges to manage system services.
