There's a bz:

https://bugzilla.redhat.com/show_bug.cgi?id=1584663

which along the way has had private comments - I probably should add the
bz to at least one of the patches, but I think because of the (probably
unnecessary) private comments in the bz, I was hesitant to do so.

I tried a different mechanism and Jano pointed out:

https://www.redhat.com/archives/libvir-list/2018-December/msg00667.html

that previous attempts were rejected due to the arbitrary text.

And I don't think it would be palatable to add N 'text' options to the
XML that map to the same N 'text' options in the mount command. So this
was the next best option as far as I saw it. That'd be one of those
never ending tasks to add the favorite option.
