questions regarding modular daemons

[Jim Fehlig]

Hi All,

I've procrastinated long enough and finally decided to switch to modular daemons 
in openSUSE Factory libvirt package. For the most part, the Factory spec file 
mimics the upstream one. I enabled with_modular_daemons and would like to 
confirm the results of my testing.

When upgrading an existing installation running the monolithic daemon, the 
monolithic daemon is still enabled after the upgrade. I suppose this behavior is 
expected, and fine IMO.

However, when installing the "modularized" packages on a system with no prior 
installation, the monolithic daemon is still installed and potentially enabled 
in posttrans. Having both the monolithic and modular daemons installed, along 
with all associated systemd socket and service files, is a bit confusing to 
users IMO. E.g. should one enable libvirtd sockets, virtqemud sockets, both?

Is the intention, over time, to remove the monolithic daemon? Perhaps we could 
start by isolating the monolithic daemon in the libvirt-daemon subpackage and 
moving the other daemons (virtproxyd, virtlogd, virtlockd, etc) to a new 
subpackage? The modular daemons could then drop the libvirt-daemon dependency, 
allowing installation without the monolithic daemon.

TIA for your comments.

Regards,
Jim
