Please create a ticket at: http://bugzilla.redhat.com More specifically: https://bugzilla.redhat.com/enter_bug.cgi?product=Fedora Mention this changeset: http://git.kernel.org/?p=linux/kernel/git/acme/linux-2.6.git;a=commit;h=34d2ea084a3bce03d73ffe64350db2813f07260c It will make the -k argument work. There is another that will look automatically at this location, but I haven't merged yet, will post here when done. - Arnaldo
