/var is typically expected to be created by /etc/rc.d/var not
initdiskless.  However, if you want to do that, you need mtree,
newsyslog, and touch which are in /usr so /usr needs to be mounted.
Using a unified root without all this separate mounting of /usr
nonsense we currently document will make this all work and save you main
in many cases.
