$OpenBSD: README,v 1.4 2025/09/01 04:51:04 helg Exp $ These tests must be run as root, on a system with free vnd0 and vnd1 slots. The system must be single-user or set to a securelevel < 1 for all tests to pass. It is also advised that /mnt be unmounted, and clean. The NFS tests create an entry in /etc/exports and start NFS server daemons for a loopback mount.
