one more nsupdate question..

[Jack Tavares]

That is unfortunate.
 
I was pretty sure I was out of luck, but I wanted to ask to make sure I wasn't missing
some "trick" somewhere.
 
I know that if I use a 
prereq yxrrset
for the record that the MX references
 
ie:
prereq yxrrset madman.test.net. A
update add test.net.500 in MX 123 madman.test.net.
 
I at least get a NXRRSET error, which is a little better.
 
Thanks

Unfortunately, since nsupdate uses the DNS protocol, and the protocol
has very limited error-reporting details, there's nothing nsupdate can
do to improve on this.  The DNS protocol has about a half dozen error
codes, and none of them are specific to this.
