Okay, thanks for explaining this. I was clearly providing bad advice
based on my flawed understanding of the situation O:-)

I think the distinction is not as obvious to someone who's not
intimately familiar with the inner workings of libvirt. And the files
in question are stored in a directory called "lock-driver", not
"lock-plugin", so I'd say we're not entirely consistent about it
internally either :)


There's another naming question that I've been thinking about: the
libvirt-daemon-driver-foo convention made perfect sense when the
(monolithic) daemon would load the various drivers, but as we
progress further towards a fully modular future it starts to become
awkward.

For example, you will have a system where libvirt-daemon-driver-qemu
is installed but libvirt-daemon is not. That feels weird.


I don't have a great solution for this. My instinct would be to have
a libvirt-daemon-foo for each foo:// that libvirt supports, and then
probably libvirt-daemon-foo-bar or libvirt-daemon-foo-plugin-bar for
each bar backend/implementation of foo://. But for the various
hypervisor drivers, those names are already taken...

Any ideas?
