webvirt-novncd and webvirt-socketiod get read-only system directories, no access to /home and /root, no new privileges, no kernel tunables, modules or cgroups, and only Unix, IPv4 and IPv6 sockets; socketiod also a private /tmp. novncd keeps the shared /tmp, where a VM's VNC Unix socket may be. They keep what they need: a pty and its console worker, TCP and Unix sockets, ssh with its configuration, writes under /srv/webvirtcloud and the service user's ~/.ssh. The units installed by the update steps bring this.
