# Creates a unique machine-id based on a local MAC address which persists over
# reboots, upgrades and reinstallation. For systems with slow loading network
# drivers (no MAC's available) dbus-uuidgen is used which persists over reboot
# and upgrades but not reinstallation. If a MAC is used it is hashed to make it
# anonymous. The machine-id is used by dbus and systemd, and to collect basic
# active-installation statistics on LibreELEC users.
