Hi,

By default, 'hostinfo' does only show the specific entries for that 
host. I believe it could be reworked to walk through the included 
default config as well, though I'm not sure if there would be any side 
impacts there (I don't think so).

As a workaround for now, for a specific host you can issue a "hostinfo 
clone=<name>" request, which should actually include the .default. 
entries applicable to it. The output format, however, is one-per line. 
(This is the interface used by certain binaries when they're doing a 
one-off lookup for a specific host from xymond.)

HTH,
