# Attempts to generate a unique machine ID based on one local MAC address
# MACHINEID SHOULD be the same between upgrades/reinstalls
# MAC is hashed so that it cant be reversed making it anonymous
# Used to help with global usage statistics, also used for dbus and systemd
# 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.
# creating machine-id, systemd otherwise does this automatically if not present.
# this we want to avoid to have the same machine-id over reboot, fallback
# to systemd's solution if this dont work here
