Thanks for clarification, that wasn't clear at the moment I looked at
it. If I knew that, I wouldn't write that RA. One remark, my RA has
possibility to check service aliveness on monitor operation and repair
that service if it hangs. I use it for libvirtd which sometimes become
unresponsive so I need to restart it before all other libvirt-related
resources begin to fail. Fortunately, modern libvirtd can be restarted
without affecting guests. Of course, that is just a hack, and that
should be fixed in libvirtd, but we live in a real world...
