Thanks.

	http://www.openbsd.org/cgi-bin/man.cgi?query=hier

That's an exceptionally useful page.
I was looking for something like that with 'apropos'.

For the archive:

	/tmp/		Temporary files; the contents of /tmp are not
			preserved across a system reboot.
	
	/var/tmp/	Temporary files that are kept between system
			reboots.
