freebsd stable - Jan 2012 - Installworld broken with an NFS /tmp

I've found the following thread from 2009 which matches what I've just
come
across while trying to install 9-RELEASE to disk on a machine with an NFS root.

http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2009-07/msg00084.html

I've just worked around this by nullfs mounting the local disk's /tmp
over
the existing (nfs) /tmp, but is there a better way of doing this - an
environment variable to specify an alternate to /tmp perhaps?


Thanks.

To "solve" the sillyrename problem visible during installworld,
I just add the following to rc.conf (nfs) once and for all:

tmpmfs="YES"
varmfs="YES" # why? probably needs for /var/tmp
