Comment 10 for bug 1743718

I looked at bringing back the old Delta, updating it to the new libvirt and fixing up the issues we had in the past:
1. not be part of the livbirt group (worse than user nobody)
2. remove users on purge

I wonder on the group it should get ...
adduser by default for a --system group picks "nogroup".
Is that safe to use, or do we also want/need to create a libvirt-dnsmasq group?
