OK, thanks for your input.  My point was to enable this for people who
don't want to (or can't) use systemtap for various reasons, but I guess
nobody can be *that* lazy to do 'package_app install_command systemtap'
and then cleanup afterwards.

I like your idea of explaining systemtap debugging with libvirt on
wiki/documentation.  I'll try to combine it with additional systemtap
examples and put it all together somehow.  But I need you to check my
grammar, since it tends to be a longer text.

Thanks again and have a nice day,
Martin
