Here's one use case - it might not be super-common, but it can't be
solved another way by the system administrator. snmpd can only bind
to one address, so to use it for both v4 and v6 need to run it twice
with different configurations; so you can use this in the config file:
addr="192.0.2.1"
listen on $addr
And for the second copy, snmpd_v6_flags="-D addr=2001:db8::1234".

Indeed, and the particular example of httpd2 would give us even
more confusion between base httpd and Apache httpd than we already
have.
