The packagegroup is a problem:

| error: Failed dependencies:
| 	xserver-xorg-extension-glx is needed by packagegroup-core-x11-xserver-1.0-r39.cedartrail
| 	xserver-xorg-extension-dri is needed by packagegroup-core-x11-xserver-1.0-r39.cedartrail
| ERROR: Function failed: do_rootfs (see /media/SSD-RAID/build-danny-cedartrail/tmp/work/cedartrail-poky-linux/opty4gles-image-1.0-r0/temp/log.do_rootfs.10973 for further information)
