Problems with lofs on Sun-3/4, SunOS 4.0, 4.0.1

[Rayan Zachariassen]

In the root filesystem, create /var/tmp (/var already exists as a mount
pt), and make /tmp -> var/tmp.  Then remember there might be files in
there if you are ever puzzled by some size vs usage discrepancy in / while
you have /var mounted.
