Bug Description

On a current intrepid setup, installing openjdk-6-jre-headless pulls in several packages that might not be suitable for a server setup : avahi-daemon, dbus, consolekit, dbus-x11...

They are pulled in through the libnss-mdns Recommends, as well as 24 other packages. Complete list follows:
avahi-daemon libavahi-common3 libavahi-common-data libavahi-core5 libdaemon0 libdbus-1-3 libexpat1 dbus consolekit libck-connector0 libdbus-glib-1-2 libglib2.0-0 libglib2.0-data libpam-ck-connector dbus-x11 bind9-host libbind9-40 libcap2 libdns43 libisc44 libisccfg40 libisccc40 liblwres40 libxml2 xml-core sgml-base perl perl-modules

As we want to promote usage of Java-based software on Ubuntu server, we might need a basic openjdk-6-jre-headless package that can be used as a dependency for a Java server package without pulling in too many packages.

I propose to downgrade the libnss-mdns recommend to a suggest (for openjdk-6-jre-headless), resulting in going from 37 dependencies for that runtime on a bare install to a more healthy 9.

According to the changelog, this Recommend was added for 6b09-1~pre1, but I am not sure it qualifies for something you want to find on all but specific setups ?

Proposed patch follows.

mdz tested the program from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=477211 and apparently it works fine without libnss-mdns installed. Matthias, does that change the situation here? Is this due to a mismatch between system nsswitch.conf and the available non-default-bit packages in a biarch environment, rather than being something we need to worry about in the normal case?

do we want to force installation of 32bit libraries?

Not really, but I think this would be more sensible than the jdk -> libmdns dep; the jdks have absolutely nothing to do with mdns whatsoever, they just use libc's resolver like any other app.

The only difference will all other packages using libc's resolver is that they are more likely to be used as 32-bits apps under 64-bits.

Ideally, we would express something like "libmdns depends on lib32mdns if you have ia32-libs".

Or perhaps we should simply make sure that if this happens, some sensible message is thrown instead of silently failing the name resolution queries?

yes, that would be helpful for the -gcj packages as well.
