Let me try again (following my own advise w.r.t. to Android which is to be very patient as it boots as all the first-boot optimizations take a long time)…
I am running the 16.06 binary build and the serial console is continually issuing the same warning messages you have highlighted:
[ 240.443188] init: Warning! Service fuse_uicc0 needs a SELinux domain defined; please fix!
[ 240.453947] init: Starting service 'fuse_uicc0'...
[ 240.460297] init: Starting service 'ims_rtp_daemon'...
[ 240.481402] init: Service 'fuse_uicc0' (pid 9839) exited with status 1
[ 240.487137] init: Service 'fuse_uicc0' (pid 9839) killing any children in process group
[ 240.495715] init: Service 'ims_rtp_daemon' (pid 9841) exited with status 1
[ 240.502035] init: Service 'ims_rtp_daemon' (pid 9841) killing any children in process group
However I can confirm that this warning does not interfere with the correct operation of WiFi. My board has booted to UI and once I have worked around bug 417 (using a wired USB mouse instead of a wireless mouse/keyboard), I am able to connect to WiFi and browse to sites using FireFox.
