The problem is that "trusted" attributes (in this case are visible and accessible only to processes that have the CAP_SYS_ADMIN capability. The current "skipUnless" guard is wrong: being root (UID 0) doesn't necessarely imply you have CAP_SYS_ADMIN. For instance this test (and thus "make test") will always fail in a Docker container unless it's started with "--cap-add SYS_ADMIN" (which, in general, is not the best thing to do).
