The /etc/nsswitch.conf file suggests otherwise, it's far from clear:

# Example - obey only what nisplus tells us...
#services:   nisplus [NOTFOUND=return] files
#networks:   nisplus [NOTFOUND=return] files
#protocols:  nisplus [NOTFOUND=return] files
#rpc:        nisplus [NOTFOUND=return] files
#ethers:     nisplus [NOTFOUND=return] files
#netmasks:   nisplus [NOTFOUND=return] files

The "obey only" suggests files will not be consulted.  The behaviour of
Joe's computer seems to indicate that kind of thing, too.

Looking in the nsswitch.conf man file, I see:

The ACTION value can be one of:

return      Return a result now.  Do not call  any  further  lookup

It's not the "return", but "NOTFOUND" that's the key. The status values are described separately, elsewhere.

An mdns resolver should return either NOTFOUND or SUCCESS for .local lookups, and UNAVAIL for all other lookups.
