Hrm, tried to enable dropbear on the current 14.2beta, but it seems the dropbearkey utility to generate SSH host keys is missing, so the initscript bugs out. I'll generate keys manually using ssh-keygen (which is in the system) later.
Also, wifi seems strange - I couldn't connect to my network by selecting it in Network Manager and then entering the key: The connection profile was created, but without saving the key. Only worked after I edited that existing connection and added the WPA key there a second time (tried several times, so I'm pretty certain I entered the wifi password correctly at least once).
