The d-bus daemon fails to start for emenlow & NUC bsps with the following error message.

With the d-bus failure X, sshd, avahi and other daemons also fail to start.

I tried to debug to see what is happening, and found out that the rootfs is mounted readonly causing all these failures.

Looking at the recent log looks like this commit in poky is the one which made rootfs mounting readonly:

    initrdscripts: mount / as read-only when live-booting
    
    So that the root filesystem can be fsck'd properly, mount it read only.  Either
    initscripts or systemd will re-mount as read-write in early boot.

A brief chat with Saul on jabber, gave information that a revert of this commit is posted on ML. and sgw is looking to pull it in his mut branch. If the revert goes in poky, then this issue should get resolved.
