Unless I'm mistaken, kusu doesn't appear to support non x86{,_64} currently. Does anyone have an idea how difficult it would be to add support for ppc64? I'm thinking to give it a shot, but I'm new to kusu and wondering if there's potential big obstacles I'm overlooking (in particular due to the fact that a x86_64 headnode won't be able to run/compile anything for ppc64).

And while I'm at it, a small bug report: When setting LANG=C, kusu breaks
in various places because the hardcoded strings don't contain the %s etc placeholders for the subsequent % (arguments).
