Since I am running a cached namesever, this data is lost when the
machine is booted.  I guess I am asking is there anyway to keep a
file on disk which is the result of continuous operation of uptime
thus not requiring "so many lookups from other servers" after the
machine has been rebooted.

For example, here is my named.boot file


; #ident	"@(#)cmd-inet:etc/named.boot	1.2"
;
;	boot file for name server
;
directory	/etc/inet
cache		.               	root.cache
primary		rn.com			rn.zone
primary		miles.com		miles.zone

and root.cache contains:
