pre-reload zone check

[Marten Lehmann]

Hello,

since BIND is very strict and refuses to serve complete zones if 
something isn't correct in there, I would like to do a test on a 
zonefile before I'm reloading BIND, so the zone doesn't go offline in 
case of an error. How can I do this? Or is there a way to tell BIND to 
serve at least those entries of a zone that are fine, so only certain 
entries aren't available, but not the whole zone?

Regards
Marten
