I also edited /etc/make.conf to include the line "MK_ZONEINFO=no" as per the
instructions in the file /usr/ports/misc/zoneinfo/pkg-descr.  However, in my
5.5 distribution, /usr/share/examples/etc/make.conf has no mention of this
variable (in fact my 7.0 FreeBSD computer has no mention of MK_ZONEINFO in
this file either).  So my question is - will the zoneinfo get clobbered if
and when I ever reinstall world?  Where can I find a comprehensive list of
available make options that can be put into make.conf?
