Hi Emil, Point 1 will be left for future patch. Current error message is following. Error: Permission denied. Hint:Try to run this test program as root. I am thinking change it. Error message will be: Error: Permission denied. Hint:Try to run this test program as root or in TTY.

Add auth mechanism and request run outside of X environment (switching to TTY should work). Then adjust the suggestion s/run as root/run in TTY/ ? > 2. As root, BO export/import failed on render node as expected.
