# According to documented First Boot Semantics writing "uninitialized" will trigger the full

# On older versions of systemd before first boot semantics were formalised, any non-uuid value
# will trigger a new machine-id to be generated, so "uninitialized" also works.
# Previously this was done here by truncating /etc/machine-id.
