	You need to look at either of the following locations.  The latter
	is used when <dump-file> contains a absolute path.


	<chroot> (as specified by -t on the command line)
	<directory> (as specified by the "directory" clause in named.conf
		     and defaults to ".")
	<dump-file> (as specified by the "dump-file" clause in named.conf and
		      defaults to "named_dump.db")

		<chroot> = "/choot"
		<directory> = "/var/named"
		<dump-file> = "named_dump.db"

		gives "/choot/var/named/named_dump.db"

		<chroot> = "/var/named"
		<directory> = "."
		<dump-file> = "named_dump.db"

		gives "/var/named/./named_dump.db"

		<chroot> = (not set as -t not used)
		<directory> = "/var/named"
		<dump-file> = "named_dump.db"

		gives "/var/named/named_dump.db"

		<chroot> = "/chroot"
		<directory> = "/var/named"
		<dump-file> = "/data/named_dump.db"
		gives "/chroot/data/named_dump.db"
