Great, thanks for pointing this out. I will certainly look at it.

I forgot to say that if you want to look at writing a new impl the code
is kept in $GIT/src/access/.
The current polkit impl is viraccessdriverpolkit.c. Implementing a new
driver involves creating a new source file with a virAccessDriver
struct that contains pointers to the methods that implement the desired
logic.
