The service verb documents the one- and two-argument forms as
SRV lookups. They should not request TXT records by default.
Only the three-argument DNS-SD form should request TXT metadata.
Reproducer:
Run resolvectl service _mysvc._tcp signed.test in the
TEST-75-RESOLVED environment, where signed.test contains:
_mysvc._tcp SRV 10 5 1234 myservice
_mysvc._tcp TXT "This is TXT for myservice"
myservice A 10.0.0.20
Before:
resolvectl service _mysvc._tcp signed.test printed TXT data
for the plain SRV form:
_mysvc._tcp/signed.test: myservice.signed.test:1234 [priority=10, weight=5]
10.0.0.20
fd00:dead:beef:cafe::17
This is TXT for myservice
After:
The plain SRV form suppresses TXT data. The DNS-SD form still
shows it:
resolvectl service '' _mysvc._tcp signed.test
