--- Comment #7 from Steven Stewart-Gallus <sstewartgallus00@xxxxxxxxxxxxxxx> ---
Jann Horn doesn't that require root privileges or certain capabilities? My
whole scenario starts from a nonroot application that sandboxes itself. I
suppose one could argue that one should use a setuid shim or invoke a daemon
that has root privileges such as systemd for these kinds of purposes though.
