GPS doesn't work. Tested using the GPS Test app.

Log highlights:

Additional information, from dmesg:

After fixing the previous error by creating the /data/gps directory on post-fs-data instead of post-fs, the error has changed:

D/libgps ( 2908): configuration_update: Waiting for IPC connection - timeout
E/libgps ( 2908): LIBGPS: Cannot communicate (write) with a GPSD
E/libgps ( 2908): IPC Communication Error 1, ../../../../tmp/14477502_250069/proprietary/deliverables/android/gps_interface/gpsi_client/GpsiClient.cpp:2213 configuration_update

Looks like I forgot to add the GPS daemon (gpsdaemon) and the creation of the GPS directories in /data/ that were in the stock init.connectivity.bcm43xx.rc. Addressed with this commit, however looks like GPS isn't working.
