Re: [libvirt PATCH 0/4] remote: switch to modular daemons by default

This series first improves driver probing when using modular

Currently when URI is NULL, we connect to virtproxyd and it looks
at which UNIX sockets exist and what binaries exist, to decide which
modular hypervisor daemon to connect to.
This means the common case results in all traffic going via virtproxyd.
Moving the logic out of virtproxyd into the remote client means we can
avoid using virtproxyd by default.
With this, we can now switch to the modular daemons by default. The
latter change primarily impacts how autostart works
When running as root we simply connect to whatever UNIX socket exists
and rely on systemd to autostart if needed. Whether the UNIX sockets
are for the modular daemon or libvirt doesn't matter - we'll look for
both. Defaults are dependent on the distros' systemd presets. I intend
to get Fedora / RHEL-9 presets changed to use the modular daemons.
I'll need to do the same for the SUSE presets, along with adjusting zypper
patterns that include libvirtd, and other downstream tweaks. Additional testing
may uncover other issues I haven't considered. I don't _think_ apparmor will
prevent things from working since there are no profiles for the modular daemons.
But yes, I'll need to work on some profiles :-).
