Thanks for spotting this. The version used is identical to the 0.24 release on github (http://github.com/vincenthz/ocaml-dbus).  Vincent works for Citrix and he's happy to waive the need for us to respin the source CD just to include this, but we'll fix the build system to include it on future source CDs.

The engineering team took a look at this, and didn't think there was a reason why the input stuff should be having anything to do with libpci. Indeed, it turned out that input_{server,client} don't actually reference anything provided by libpci, so it won't be dynamically linked against it. libpci shows up in the output of ldd because of a bug in a configure script used to build the daemon. 

You can demonstrate this simply by running sed on the binary to remove libpci from the list of expected libraries, e.g. "sed -i 's/libpci.so.3/libnsl.so.1/' input_{server,client}" [libnsl is used here simply because it is not used by input_server/client and happens to have the same length name.]  If you run the sed script and reboot you should see that input_server/client binaries still load correctly (as they were never actually being dynamically linked against libpci) and that there is no loss of functionality.  Hence, input_server/client don't use any GPL libraries.

We expect to release all of the extra bits and pieces like this as GPL and submit them for consideration for the XCI tree, and are working on appropriate legal signoff. Stay tuned...

Citrix XenClient Product Team.

Hi,

Other package that is missing is ocaml-dbus
(http://projects.snarc.org/ocaml-dbus/) used by the
xenclient-toolstack.
