hostname, resolve, tmp, and var scripts. The latter three are new and were repo copied. These scripts no longer depend on being booted with and NFS root instead attempt to automaticly create mfs /tmp and /var volumes if the they are not writable. This behavior can be overridden in /etc/rc.conf. Reviewed by: luigi, pjd
