Subject: [PATCH] host/rootfs: Set no_new_privs in PID 1
Date: Fri, 05 Dec 2025 11:01:30 -0500	[thread overview]
Message-ID: <20251205-no-new-privs-v1-1-56cbdf7de44f@gmail.com> (raw)

This prevents any program on the host from gaining privileges via
execve(), ever.  There are currently no such programs on the host so
this should be a no-op for now.
