 The following "tags" are possible:
-- "cgroups-missing" — the kernel was compiled without cgroup support or access
-  to expected interface files is restricted
 - "var-run-bad" — /var/run is not a symlink to /run
 - "overflowuid-not-65534" — the kernel user ID used for "unknown" users (with
   NFS or user namespaces) is not 65534
