One obvious issue (which is on my todo list) is that prefdm.service
currently has a hard dep on network-up. We need this if the user has
network based auth (e.g. ldap, NIS etc.)

In your SSD case, this accounts for at least 25s delay.

We need to have a little service (or something in drakauth) that
adds/removes the dependency on network-up when a network authentication
mechanism is detected.

Not sure how we handled this in mga1 (possibly not at all!).
