Nss-mdns is a plugin for the gnu name service switch (nss) functionality of the gnu c library (glibc) providing host name resolution via multicast dns.

this transitional package exists to upgrade amd64 systems from lib32nss-mdns:amd64 to libnss-mdns:i386. because direct cross-architecture dependencies are not yet supported, it depends on an intermediate package, libnss-mdns-i386, which is only available on i386.
