Well human error would help :)  But also allowing the container to have
all the privileges it needs to do lvm+mounting means that anything in
the continer could mess with the host.

If it's also a throw away test host, then there's nothing to worry
about.

Nothing *should* go wrong :)  It's just that by having access to the
host disk devices, any malware/bugs in the container can easily hose
your host, replace your /sbin/init, etc.
