Thanks for hints, it seems this the way to follow.

Board numbers, customers, locations, etc. are stored in database. That
way it is always known what's going on and the only requirement is to
not allow two same MAC addresses at time. As a customer who doesn't care
about implementation details I would assume that new/repaired device
will behave exactly as before. Of course I'd vote for unique MAC too,
but I'm not the one who decides...

Sure, that's why I like open source projects :)

Even _most_ firmware has a undocumented way how to change MAC address
(it's note only, your point is certainly right :))
