STEPS TO REPRODUCE
1. Configure a qemux86 image by adding the following line in conf/local.conf in order to enable weston compositor in the image:
 CORE_IMAGE_EXTRA_INSTALL += "wayland weston"

2. $ bitbake core-image-sato

3. Launch the qemu image:
$ runqemu tmp/deploy/images/bzImage-qemux86.bin tmp/deploy/images/core-image-sato-qemux86.ext3 

4. Connect to the qemu via ssh and kill xinit:
root@qemux86:~# killall xinit

5.a) Run weston:
root@qemux86:~# weston



EXPECTED RESULT
Weston is displayed on top of X without any configurations.

ACTUAL RESULT
Instead, the following errors appear:

OTHER COMMENTS:
I have changed the permissions from 775 to 0700 for the XDG_RUNTIME_DIR, but I still have the errors regarding the weston.ini file which isn't created and also the missing shared objects files.
