    Add patch: 602_nx-X11_initgroups.full.patch. Fix calling setuid and setgid without setgroups or initgroups. There is a high probability this means it didn't relinquish all groups, and this would be a potential security issue to be fixed. Seek POS36-C on the web for details about the problem. (Fixes: #293).
