When installing Postfix on a brand new NetBSD 1.4 system, I
noticed a /var/spool/postfix/etc directory, which is used neither
by a stock Postfix nor by the NetBSD Postfix package.  This
directory comes from the base.tgz file:

drwxr-xr-x root/wheel         0 1999-05-03 15:06 ./var/spool/postfix/etc

I noticed this extra directory with a i386 install, I didn't
check the other ports.
