Well, I do the way /etc/rc.diskless2 does :
...
if [ ! -h /tmp -a ! -h /var/tmp ]; then
mount_null /var/tmp /tmp
fi
...
Sometime, you have to trust someone...
I trust FreeBSD guys ;-)
I'll give the symlink a try but, anyway, I found a way to make the
kernel crash at will. If it crashes, it means it is buggy somewhere
and it needs a fix not a workaround...

I don't have ext2fs...
