IIUC this basically acts as a synchronization point during shutdown:
no guest will be torn down before it has been reached, and the daemon
will not be shut down either. On a default install, this is where
libvirt-guests.service would have a chance to perform the ON_SHUTDOWN
action, but the local admin or management application can replace
that with their own custom implementation.

This configures the remote side of the connection.

Server-side, and not specific to any hypervisor.

These are for access to a local daemon, not remote access. And again
it's the server configuring what clients should be allowed to connect
to it.


Assuming I've gotten all of the above right :) then it seems to me
that all these files need to go in one of the server-side packages.

I think we should just have a libvirt-daemon-common package that
includes what you currently have put into the libvirt-daemon-client
package plus these files, and have all hypervisor drivers depend on
it directly. Which would basically keep things as they are: right now
installing libvirt-daemon-driver-qemu results in these files begin
present because they're part of the libvirt-daemon package, and after
this change the same would be true except for the monolithic daemon
not coming along for the ride.
