Then after creating /home/phablet/.display-mir, usc fails to load

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

Something might be broken in our environment after the nested merge.

To reproduce my failures, flash your maguro with 'phablet-flash
cdimage-touch -b --pending'.

Seems there's also a bug when restarting unity8:
