The Sato shutdown icon just runs "halt" which the rootless X user does not have permission to run, so it does not work on atom-pc for example.
The rootless X image doesn't even boot into graphics at the moment. A segmentation fault in X is preventing that...
Apparently, x86 images only have problems booting into X. arm/ppc/mips core-image-sato images boot just fine...
The segfaults for x86 are due to the fact that xf86-video-vmware needs to access the I/O ports but it cannot without root privileges. It should work just fine on real HW (atom-pc for example) since xf86-video-intel uses KMS.
