'Twas brillig, and Damien Lallement at 24/01/12 14:06 did gyre and gimble:

+
+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!).
