Comment # 3 on bug 960464 from Jan Engelhardt

The way this currently works is such that the unprivileged user starts
cdemu-daemon, requiring that the user has permissions on /dev/vhba_ctl.
cdemu-daemon will then sit on the user's dbus bus and listens for cdemu-client
requests.

As to how the user gains rw permissions for /dev/vhba_ctl���

I am not totally sure we can just chmod a+rw it like /dev/fuse. What's the
security teams take on it?
