@pkgsysconfdir@/hosts is a file which may be used
to define static host name to IP address mappings for multicast
DNS. This is especially useful when publishing DNS-SD services
on behalf of other hosts. See for more information.
The file format is similar to the one of
/etc/hosts: on each line an IP address and the
corresponding host name. The host names should be in FQDN form,
i.e. with appended .local suffix.
