These 'cat' calls should all really be reported as diagnostics
rather than just sent to stdout directly. We should probably
just use the standard 'Slurp' module from CPAN.

eg, put a 'use Slurp' at the top of the script then
replace those 2 lines with

   my $hookdata = slurp($hook->{name});
   diag "hook script: $hook->{name} '$hookdata'";

s/invocated/invoked/  (and in a few other places later)

As mentioned in the previous patch, it is probably best to wrap the
entire test block in a

  SKIP: {
     my $uri = $conn->get_uri();
     skip 12, "Not using QEMU/LXC driver" unless
          $uri eq "qemu:///system" or $uri eq "lxc:///";

     ....all test cases...
  }

Daniel
