Исправление intelfx, (текущая версия) :
Насколько я понимаю, стандарт (RFC 3927) так рекомендует.
If the host has access to persistent information that is different for each host, such as its IEEE 802 MAC address, then the pseudo-random number generator SHOULD be seeded using a value derived from this information. This means that even without using any other persistent storage, a host will usually select the same IPv4 Link-Local address each time it is booted, which can be convenient for debugging and other operational reasons.

Собственно, в systemd решили использовать для этих целей комбинацию MAC и адреса сетевой карты на шине.
