Apparently if you have a Lion 10.7.2 Server set up as an OD Master, and you’re backing it up using Time Machine, and at some point you attempt to do a full system restore using Time Machine… the resulting restore will be non-functional because Time Machine currently can’t handle open /var/db files). This was info was sent to me from a friend that I trust, who said he confirmed it with an Apple Enterprise Tech after it happened to him.
